Filed Oct. 27, 1958, Ser. No. 769,775

19' Claims. (Cl. 230-149) While my invention relates to elastic fluid compressors in general, it applies more specifically to a multiple stage cammed, cam chambered and bladed, pressure stage compounded, rotary cam chambered, elastic fluid compressor, operative in conjunction with an internal combustion turbine unit motive power assembly applicable to an automotive vehicle.

Such an assembly could be similar to that of my recent patent application Serial No. 743,873, filed June 23, 1958, now Patent No. 2,915,876 issued December 8, 1959, wherein my pressure variable ratio reversible transmission coupler, Patent No. 2,799,182, issued July 16, 1957, and my multiple drive and pinion geared, pressure stage compounded compressor Patent No. 2,876,947, issued March 10, 1959, were used, and which latter may be made interchangeable with present invention compressor. Above patents are obtainable from the US. Patent Oflice.

Providing a pair of, axially oppositely located, annular shaped, cored cavity type of compressor stator heads, with one located adjacent either end of, the outer stator member of the compressor, and of the compressor rotor, and forming a front head lubricating fluid reservoir and a rear head compressed elastic fluid accumulator manifold. Providing means for axially pressure balancing said rotor between said stator heads. Providing means for radially pressure balancing, each multiple blade between its respective cam and the bottom of its respective blade slot. Providing means for lubricating each 1st stage blade from a broached groove forming a part of its blade slot. Providing cooperative access means, forming a part of each 1st stage blade for intermittently supplying elastic fluid to the respective adjacent 1st stage cam chamber. Providing a plurality of rows, one row for each 1st stage cam, of access ports with one row initiating adjacent a trailing edge of each lst stage cam and therefrom extending diagonally through the rim of said rotor, at a location between an outer and an inner cam land, to adjacent the leading edge of the adjacent 2nd stage cam and for simultaneously, with such supplying of such elastic fluid to such respective 1st stage cam chamber, discharging compressed elastic fluid therefrom into the adjacent respective 2nd stage cam chamber, by and through such, self contained short coupled, row of access ports. Providing means, through multiple porting extending radially in and multiple wicking extending axially in said compressor rotor, for dynamically lubricating the compressors rotative and slidable parts during the rotation of its rotor. Providing an elongated, one direction rotatable in-common driving shaft, which latter extends throughout the entire motive power assembly mentioned, forms the turbine rotor shaft, the compressor rotor driving shaft, a power delivery coupler driving gear driving shaft, and, is adjustably journalled upon an opposed pair of roller bearings, with one of the latter mounted in each of the stator heads. Also providing other minor improvements as will be disclosed hereinafter.

With reference to the figures of the accompanying drawings: Fig. 1 illustrates several transverse sections through an opposed dual cammed type of my compressor, and as the right upper 45 section would appear on the dotted and solid line 1-1 of Fig. 8, as the right lower 45 section would appear on the dotted and solid line 1'-1', as the right intermediate lower 72 section and the left onehalf section would appear on the dotted line 1"-1", and as the right intermediate upper 18 section would appear on the dotted and solid line 11' of said Fig. 8; Fig. 2 is an enlarged detail section of the 1st stage blading as on the left side of Fig. 4; Fig. 3 is an enlarged detail section of the 1st stage blading at a point slightly closer than as in the right side of Fig. 4; the latter figure is a transverse section through the opposed dual cammed type of compressor on the dotted line 4--4 of Fig. 8, excepting with the compressor rotor rotated from position it is in Fig. 1; Fig. 5 is a detail section of the coupler fluid supply connection as on the dotted line 55 of Fig. 1; Fig. 6 is an enlarged detail illustrating a method of mounting resilient coil springs in and providing pressure equalizing holes in either the 2nd and/or the 3rd pressure stage blades; Fig. 7 is an enlarged detail section of one of the last pressure stage discharge, non-return, check valves as on the broken line 7-7 of Fig. 1, when the 3rd pressure stage is the last pressure stage, otherwise such discharge valves could be in a similar relation location to the 2nd stage blades, if the compressor were two pressure stage compounded and/or could be in a similar relation location to the 1st stage blades, if the compressor was of single stage construction; Fig. 8 is jointly a longitudinal broken away plan and section of the compressor of Fig. 1, and a portion of the adjacent internal combustion turbine, at its left end, and a portion.

With reference to the symbols of the drawings, similar symbols represent and indicate similar parts in the several figures: The numeral 1 indicates the elongated, turbine rotor 1R, shaft which extends throughout the unit motive power assembly as the common driving shaft thereof for rotatively driving the compressor rotor 3R, of the compressor 3, and the sun-gear SG of my, previously mentioned patented, combined hydrodynamical and quadruple compounded planetary gearing driven, pressure variable ratio reversible, combined torque convertor and automatically operative power delivery transmission coupler 5. The internal combustion turbine 2 is similar to my previously mentioned turbine Patent No. 2,915,876 and is secured together concentrically, to shaft 1 rotation axis, to and with the compressor 3 by the stud-bolts 2b. This one direction rotatable shaft 1 is rotatively journalled upon the opposed pair of adjustable tapering roller bearings 1B and 1B (Fig. 8) respectively mounted in the cored forward head FH and rear head RH of the compressor 3, and is shouldered against the shaft snap ring 1r by the inner race of bearing 13, and is adjustable axially by the multiple of annular shaped shims AS, adjacent the inner race of bearing 1B, and is further journalled upon the set of needle-bearings 4NB, in the stator 48 of coupler 5 and upon the roller bearing 58, in the end of the coupler casing 5C. The latter is rotatively journalled upon said stator 43 and the shaft 1 respectively upon the opposed pair of adjustable tapering roller bearings 5B and 5B. The coupler end of shaft 1 is provided with the external helical spline lHS which rotatively drives the coupler sun-gear SG and also provides the latter and the coupler planet-gear-carrier PGC with an axial thrust to the right in Fig. 8. The intermediate portion of shaft 1 is provided with an external spline 18 for slidably receiving and rotatively driving the compressor rotor proper 3R and the worm W, which latter rotatively drives a transversely extending pump drive shaft DS through the worm-wheel WW, see Fig. 1.

If the compressor is of triple pressure stage form, Figs. 1, 4, 8 and 9, it is then provided with: an elongated outer rotor OR which is flanged adjacent one end thereof integral with the rotor proper 3R and is provided externally to OR, and extending throughout the length thereof, with a multiple of indented and/or concave shaped 1st pressure stage cams C; and is provided internally to OR with a similar number, in a similar radial plane, of indented 2nd pressure stage cams C"; and wherein, between adjacent edges of adjacent 1st stage cams C, and similarly between adjacent 2nd stage cams C respectively, an outer and an inner cylindrical land ridge R' and R" is provided in the same radial plane with one another, and which lands R are a close rotative fit within theouter stator bore OSB, while the lands R" are a similar fit over the periphery of the inner stator IS; wherein OR is also provided with several rows of access ports AP, with one row extending diagonally, from each trailing edge of each C into the leading edge of each adjacent C", through the rim of OR between adjacent lands R and R"; and wherein OR is further provided with several axial holes H extending therethroughout, with one located between each adjacent land R and R" and containing felt wicking, and each provided with a row of semi-radially extending lubricating fluid, distributing holes LH and may also be provided with a radially extending fluid pressure supply hole PH, located in the flange of rotor SR and connecting H with one of the, axially extending, fluid pressure supply holes PH symmetricaly spaced within the inner rotor IR; and, wherein the 2nd stage cams C" are relatively shorter than the 1st stage cams C and are the same length as stator IS, which latter extends from the flange of SR to th projecting boss PB on RH.

The inner rotor IR, in such case, is then provided with:

an elongated annular shaped body portion integral with the rotor proper SR and provided externally thereto with a multiple of elongated 3rd pressure stage cams C' of equal number to and in the same radial plane with cams C and C", and which cams C are provided with a multiple of land ridges R which are a close rotative fit within the inner stator bore ISB; wherein the fluid pressure supply holes PH are symmetrically spaced within and extend axially in 3R; and, wherein the latter is internally splined axially, and is axially slidable over and rotatively driven by the spline of shaft 1. In such triple pressure staged compressor, the inner stator IS thereof is I elongated and of annular shape and extends from the rotor flange to the rear head projecting boss PB and is provided with: a series of elongated body and thread fitting stud-bolts 3b which may secure it, concentrically to shaft rotation axis with and to the rear stator head RH boss PB; a multiple of rectangular shaped 2nd stage blade slots BS each extending throughout the length of the outer surface of IS and each adaptable to slidably receive its respective 2nd pressure stage slidable blade SB, and a similar multiple of rectangular shaped 3rd pressure stage blade slots BS each extending throughout the inner surface of IS and each adaptable to slidably receive its respective 3rd pressure stage slidable blade SB', and, wherein the rotative degrees of location of each multiple blade slot of each pressure stage ispredetermined and is in accordance with the number of blades used in each pressure stage, but wherein such number should normally be equal throughout the pressure stages; wherein I8 is also provided with multiple rows of diagonally radially extending therethrough access holes h, located one row between each adjacent pair of 2nd and 3rd pressure stage blade slots, and through which to discharge compressed elastic fluid from adjacent 2nd to adjacent 3rd pressure stage cam chambers respectively CC and CC, which latter are formed between each respective cam C" and the outer surface of IS, and respectively between each respective cam C and the inner surface of IS; and wherein the latter is further provided, adjacent the rotor flange end thereof, with an annular shaped rectangular recess AR which is filled with felt wicking and is in communication, through oppositely located axially extending leak-off holes L0 in rotor 3R flange, with an annular shaped pressure balancing recess in the adjacent projecting boss PB of the front stator head FH, see Fig 8, and, which holes L0 and balancing recess will be described hereinafter. As the 3rd stage cam chambers CC happens to be the last pressure stage cam chambers in this case, then each cam chamber C is provided with a non-return, spring loaded, axially ex tending discharge check-valve DV, which latter are each located in the rear stator head RH in a predetermined location in respect to each last pressure stage blades and each opens away from its respective cam chamber into the cored cavity accumulator manifold AM in the rear head RH, and is provided with an extremely small, valve closing, compression clearance space in its cam chamber.

The compressor outer stator OS is elongated and annular shaped and consists of: two oppositely located outer end diameters that fit closely within adjacent counterbores CB, one in each stator head FH and RH, for retaining OS concentrically in line axially with and to such heads FH and RH by the series of symmetrically spaced studbolts 3b, which latter are shouldered against the outside or RH, extend throughout OS, including its numerous outer cooling fins CF, and are threaded into FH; an inner bore OSB extending throughout OS and adaptable to slidably and rotatively receive the outer rotor OR with its multiple of cam land ridges R; a multiple of rectangular shaped lst pressure stage blade slots BS extending throughout the length of said bore OSB and each slot adaptable to slidably receive its respective 1st pressure stage slidable blade SB which together are located in a predetermined manner as described hereinafter in accordance with the number of blades to be used in each pressure stage; a multiple of elastic fluid supply inlet manifolds IM each extending axially in OS and located, in a predetermined manner, with one adjacent each 1st pressure stage blade slot BS and each IM connected via a closed manifold means, which may be a fluid pressure tight annular shaped manifold IM' and/ or copper tubing CT, to an in-common throttle valve manifold TVM, having a throttle valve TV, whereby the supply to each IM may be controlled by such TV and the supply of elastic fluid to the latter may be through and an air filter means; and, a multiple of rows of diagonally extending access holes DH, with one row extending between each 1st pressure stage blade slot BS and the adjacent inlet manifold IM, and which holes DH will be described in detail hereinafter.

Wherein the indented multiple cams C of the lst pressure stage in conjunction with the lst pressure stage multiple blades SB and with the bore of the outer stator OS form the multiple 1st stage rotatable cam chambers CC, also wherein the total displacement of the 1st pressure stage, of this positive displacement rotary compressor, controls the total output capacity of the compressor during each revolution of its rotor 3R. Therefore the formula for the computed capacity of the compressor would be; an individual displacement of one 1st pressure stage cam chamber CC'X (number of 1st stage indented cams CX number of 1st stage blades SB). Therefore, as an example, assuming the individual displacement of CC to be 6.5 cub.", then X (cams C to be 6, X blades SB to be 6)=234 cub. total rated displacement of compressor 3 during each revolution of its rotor 3R. Also as the 1st pressure stage blades SB, were previously mentioned as being located in their respective blade slots BS in the bore of OS in a predetermined manner in accordance with the number of blades SB used in such 1st pressure stage, the clockwise degree of location recommended when the multiple of blades SB used in such lst pressure stage is: Two blades90 and 270; three blades60, 180 and 300; four blades 45, 135, 225 and 315; five blades 36, 108, 180, 252 and 324; and, six blades- 30, 90, 150, 210, 270 and 330.

Inasmuch as the last pressure stage discharge valves DV are constructed and located so as to require practically nill compression loss, and as a single and/or a two stage pressure compounded compressor, of this type, will compress air to 11 atmospheres and would obviously be less expensive to build and maintain, the latter type is illustrated in Fig. 10.

The lst stage blade slots BS are each provided with: a semi-circular broached groove BG extending therethroughout and which may each be connected through annular groove AG" and diagonal access hole AH to the annular groove AG, in FH casting, and thereby providing each blade SB with a closed circuit fluid supply from 3R, which fluid is distributed intermittently through holes Dh through SE, to both sides of latter; a series of diagonally extending access holes DH, in OS, connecting a similar series of radially extending semi-circular slots SS, in each SB, with the adjacent IM for intermittently supplying elastic fluid to leading end of each CC during the normal radial sliding of each SB; and, a plurality of elongated threaded guide bolts GB, Fig. 3, one for each blade spring CS and aligning with latter where threaded through OS, and, through which threaded holes such springs may be conveniently exchanged.

With reference to Figs. 3, 6 and 10, all the compressor blades SB, SB and SB should be crowned, and should each be provided with a plurality of pressure equalizing holes PE, PE and PE respectively, extending from such crowns, via a spring chamber bore in each blade, into the blade slot at opposite end from the cam, whereby with air pressure applied at the cam ends of such blades and retainer spring pressure, from springs CS, CS and CS respectively, applied at the blade slot ends thereof, if air pressure tends to separate blades from cams, then such pressure tends to equalize at cam and slot ends of blades so springs return blades to contact with cams, thereby resulting in a minimum friction bearing of blades against cams.

Inasmuch as any lubricating fluid which is introduced into the 1st stage cam chambers CC, from any source, will lubricate the 1st stage cams C and blades SB, and will then be carried over into CC", CC and AM, and must be returned to reservoir FR, such return means is provided in the form of an automatically operative trap float valve FV, Figs. 1, 4 and 9, which should be accessible and be provided with: a plurality of stud-bolts b for bolting the body of FV to a projecting boss of RH; a vented throughout float valve stem FV, guided in the threaded bonnet TB and seating towards. the outlet to connection tubing T leading to FR in FH; a bellshaped, closed top open bottom, float F, pressed over and soldered to FV and floatable within float chamber PC which latter is in communication through slotted access SA with AM; and, whereby whenever fluid rises higher on outside than on inside of F, then the latter will be lifted from its seat and vice versa.

In Figs. 1 and 8, for purposes of axially pressure balancing 3R between the annular projecting bosses PB of PH and RH, the rotor 3R is provided with: a pair of axially opposite annular shaped recesses AR, each a close rotative fit over its respective boss PB; a pair of radially oppositely located 1eak-oif holes LO extending.

axially through a flange portion of 3R and connecting the annular recess AR, in front end of IS, with the adjacent recess in the face of the front boss PB; whereby when pressure in CC and CC" displaces 3R for.- ward away from IS and against front PB, the latter becomes a thrust bearing which is amply lubricated, and such pressure leaks by front end of IS, thence through holes LO into recess of front boss PB, and, thereby tends to equalize forward thrust of SR as well as the pressures in recess AR and front boss recess. When the compressor is of two pressure stage form, as in Fig. 10, then; the inside diameters of both bosses PB and recesses AR as well as IS may all be equal; an annular portion of 3R may then extend to rear, from flange thereof, a close fit inside of IS and may be lubricated from holes PH; and, thereby resulting in front end of IS also becoming a thrust bearing amply lubricated. When the compressor is of single stage form, not illustrated, then; IS complete is eliminated, the outside diameters of both bosses PB and recesses AR may then remain as before but the inside diameters thereof may be increased to old outside diameters of IS; both ends of 3R may then be flanged over such bosses PB and latter may become thrust bearings amply lubricated from front boss PB, with rear PB lubricated through axial holes H; the rear side of 3R flange may extend straight inward to its hub; and, the holes PH need only to extend from front end of 3R to its flange.

Miscellaneous applicable details: In the figures, any complete arrows indicate direction of rotation of parts, while any incomplete arrows indicate direction of fluid flow and/or the direction of sectional views. In Figs. 1 and 8, the helix angle of worm W should cause latter to bear against rotor 3R. In Figs. 1, 4, 7, 9 and 10, the last stage discharge valves DV are each coil spring CS-loaded, are slidable axially in chamber bore CB, discharge into AM, are provided with threaded bonnet TB and are removeable from RH. In Figs. 1, 4, 8, 9 and 10, the automatically operative pressure regulator PR, consists of; a slidable piston SP, in PR bore, supplied with fluid under pressure at one end thereof from base of AM via connection tubing CT, and opposed at its opposite end, by an adjustable load coil spring CS, and connected at this latter end via a spring wire SW and a swivel pin bell-crank BC to an air supply throttlevalve TV of TVM, and whereby, whenever the fluid pressure is greatest on SP in PR, then TV is closed, and vice versa, and, wherein setting of CS may be above 12 atmospheres. In Figs. 4 and 8: as the cored cavity in RH forms AM, then the outlet valve OV, thereof AM, not illustrated in detail, should be a combined multiple disc strainer and solenoid coil operative checkvalve, openable whenever an ignition switch is turned on and vice versa. In Fig. 8; the cored cavity in FH forms a static head lubricating fluid reservoir FR, and is provided with the combined vented filler plug and oil depth rod FP, the drain plug Dp, and, two series of non-rotative spring seal rings SR in hub of 1R, and SR in shaft 1. In Figs. 1, 8 and 10, the compressor 3 is lubricated throughout dynamically by lubricating fluid rotatively carried in the axial pressure supply holes PH in rotor 3R thereof, and wherein the quantity of fluid carried in each PH depends upon the location of the top of the eccentric central access BA, in FH, in respect to top of top PH, and, also wherein during rotation of worm wheel WW latter will throw fluid over top of EA bottom into lower holes. PH. In Figs. 1, 8 and 10: depending upon the fluid pressure desired in the axial holes H, the latter may each be supplied from one of the holes PH through the relatively long radially extending hole PH, Fig. 1, if a higher pressure is required; and/or, if a lower pressure is required, may each be supplied from two opposite holes PH, each normally provided with a pair of oppositely axially located radial holes RH each extending into the inner annular groove AG, Fig. 8, one in each opposite boss PB, thence radially through the connection holes Ch into the outer annular grooves AG, one of each in each PB; and, thence through relatively short radial holes, similar to PH, Fig. 10, one in each end of 3R into both ends of their respective hole H, and, wherein the opposite recesses AR and bosses PB are simultaneously lubricated from grooves AG and AG. Whenever it becomes necessary to use over two manifolds IM, then in lieu of using two annular shaped tube manifolds CT, as in Fig. 9, only one annular shaped fluid pressure tight manifold IM need be used, as in Fig. 10, for connecting manifolds IM to TVM, and, in the latter case IM encloses four adjacent cooling fins CF. With reference to Figs. 1, 8, 9 and 10, while two oppositely located grooves BG could be supplied with lubricating fluid directly from PR; in normal practice each BG may be connected at one end thereof to the annular groove AG", on the rear side of PH, Fig, 8, thence via the semi axial and radial access hole AH in FH to the inner annular groove AG in the front boss PB, thence via two opposite radial holes RH into two radially opposite axial holes PH. With reference to Figs. 1 and 8, the compressor 3 is secured, concentrically with shaft rotation axis, to turbine stator 2 by the multiple of stud-bolts 2b and by the flanged boss P3 of PH bearing radially against adjacent cooling fins CF of 2; and, is secured, concentrically with shaft rotative axis, to coupler 5, of the unit motive power assembly, by being bolted, with multiple of bolts 4b, to the heat treated and ground flanged stator 45 of such coupler 5; also, wherein Figs. 1, 5 and 8 illustrate connection means for supplying fluid towithin 5, through tubing TF, for pressure variable ratio reversing of 5; and, furthermore as latter is similar to my previously mentioned Patent No. 2,799,182, and the turbine 2 is similar to my previously mentioned Patent No. 2,915,876, the symbols of neither will be further described herein. With refereuce to Figs. 1, 8, 9 and 10, any fluid that bleeds into the lower manifolds IM during period 3R is idle, will be induced back into 1st stage through SS of blades SB, thence through 2nd and 3rd stages into AM, and, thence returned to FR via float-valve FV, Fig. 4, so will not be lost.

With reference to Fig. 8; the unit motive power assembly, including the compressor '3, may be supported between the car frames by opposite pairs of front and rear brackets, similar to PE and RB respectively, secured to FH and RH; and, a shield 5s may be secured to latter and extend to rear over the top of coupler 5 for protecting latter.

In order to quickly understand the operation of this type of compressor, it should first be understood that simultaneously with the supply of elastic fluid to one end of any rotatable cam chamber, that compressed elastic fluid is being discharged from the opposite end of this same cam chamber, and this fact applies regardless of the number of cam chambers in each stage and/or the number of pressure stages in the compressor. Starting with the rotative parts in position as in Fig. 1 and assuming the compressor has been operating, then in tracing one side sequence only: filtered air under atmospheric pressure from TVM is induced into left upper CC through; left CT, IM, DH and SS, in series; simultaneously therewith compressed air is discharged from left lower CC through lower access ports AP into right lower CC; simultaneously therewith compressed air is discharged from right upper CC into right lower CC through adjacent holes h; and, simultaneously therewith compressed air is discharged from right upper CC into AM through the adjacent discharge valve DV opening into AM.

While any number of indented cams for each stage, and any number of pressure stages may be used in my compressor, I would recommend either four and/or six cams for each stage, in preferably a two pressure stage compressor of this type, for the usual automotive vehicle internal combustion turbine motive power assembly in conjunction therewith.
