VARIABLE RADIATOR.
Application ma January aim. man R0. 407.
to large changes in temperature, due either to changes in the temperature of the surrounding medium, or to changes in speed and this is particularly so in the case oi dirigibles and aeroplanes. I
To overcome this objection it has been proposed to make the radiating capacity of radiators intended for these purposes, variable, so that it becomes possible to maintain the circulating 'water at the most suitable temperature compatible with the maximum. out-put of the motor.
It has also been proposed to arrange I valves controlled by thermostat devices in conduits within the radiator to regulate the proportion of the circulating water which passes through the radiator .tubes, the remainder of the water being by-pa through the conduits. In these radiators the side framemembers of the radiator may form the conduits or the latter may be con- I5 ing the invention. I if longitudinal sectional rotatable member 0 is fastened to incorporated in the stituted by pipes or other hollow formations body of the radiator.
The accompanying drawing shows bymway of example one form of apparatus-em dy- Fig. 1 thereof is a view. z
Fig. 2 a transverse sectional view on line 2 2,'Fig. 1 looking in the direction of arrow B, an Fig. 3 a side elevation. 7 As will be seen from Fi 1, the radiator comprises a' central body, ivided into two chambers by means of a diaphragm supporting a' ve N controlled from the exterior byameberEQ The valve N may be of any suitable and convenient form and inthe drawingit is shown inthe form of a rotary valve 'avin an outer bell-shaped. member. X, fastene seas to make a water-tight joint with the wall Y of the centralbody and a rotatablymounted bell-shaped mem r C seating on the inner surface of the member X. The
ssed to such an extent that a shaft F 'which passes to the outside of theradiator,
through a water-tight gland G, where it is connected to a control lever'H. .A spring J serves tokeep the rotatable member iinxcontact withthe innerv surface of the member X. Both members X. and C are provided Y with a number of holes D and D respec- .so formed and disposed that, by a I rotary movement of the inner member C, the
tivey,
two sets of holes may be brought completely into or out of register JVlth one another or to any intermediate position. The first chamber communicates with the second by way of a group of radiator tubes M in such a manner that when the valve N is closed the whole of the water circulati between P and-0 is obliged to'pass-throu g fi the tubes M and the water thereof is exposed over a large radiating surface.-
. If the surrounding temperature drops or if the travelling speed increases to that the water is' cooled to too great an extent, it is 'suflicient'to 'gradually" open the valve N to remove a gradually increasing proportion'of the circulating water from the cooling influence. It is possible too e Water flowing from 0 remains exactly atthe desired temperature. If the valve is of a suitable size and is fully opened, the flow of water across the radiating tubes M may practically cease.
To'tensure that the steam which may be 7 generated inside the radiator can escape and n'the said valve radiating action becomes too great and the] that the radiator may be em ied of the whole of its water'content,.t e radiatin tubes M are connected to a'. central tank provided with two valved unions theupper "one Z servin as an. outlet for steam, and
the lowerone the removal of the water becomes necessary. 5 The tank Z, which isv of annular shape, encircles the tubes and'is in aplane normal to the same; said tubes passing through holes in, the tank Z. and being soldered thereto. The tubes M communicate with the tank Z by holes K. h
, as an outlet for water when- It will-be understood that man other constructions of radiator are possi le without departing from the scope of the present invention.
,Haying new particularly described and ascertained the nature of my" said invention, and in. w manner the same is to be performed, I declare that what I claim is 1. A variable radiator, comprising a byfor operating said'valve so as to control at will the quantity of circulation water which passes through said by-pass from one chamber directly to the other and thereby vary the quantity of .water passing through said tubes.
2, A variable radiator, comprisin a bypass; a valve in the by-pass dividing the interior thereof into two chambers and embodying a perforated bellrshaped member fixed in the by-pass, and a perforated movable member associated therewith; a group of coolingtubes providing communication to which the movable valve member is" between said chambersiand with respect to which tubes the by-pass is centrally disposed; a shaft; mounted in the by-pass and secured, said shaft projecting exteriorly of the by-pass at one end; and means connected to the exterior end of the shaft for rotating the movable valve member and bringing its perforations into or out of registration with those of the fixed member so as to controlat will the quantity of circulation water which passes directly from one chamber to the other and thereby vary the quantity of water passing through said tubes. 7
3. A variable radiator, comprising a bypass; a valve in the by-pass ,dividlng the inter-tor thereof into two chambers; a group of cooling tubes providing communication between said chambers'and with respect to which tubes the by-pass is" centrally disposed; means external to the radiator for operating said valve so as to control at will the quantity of circulation water which passes through said by-pass from one cham- D berdirectly to the other and thereby vary the quantity of water passing through said tubes; and a tank with which all of the tubes communicate having separate outlets for discharging steam and water from the tubes.
4. A variable radiator, comprising a bypass; a valve in the by-pass dividing the interior thereofinto two chambers; a group of cooling tubes providing communication between said chambers and with respect to which tubes the by-pass is centrally disposed; means external to the radiator for operating said valve so as to control at will the quantity of circulation water which passes through said by-pass from one chamber directly to the other and thereby vary the quantity of water passing through said tubes; and an annular tank encircling the tubes and with which all of them communicate, said tank being disposed in a plane normal to the tubes and having separate outlets for discharging steam and water from the tubes.
5. A variable radiator, comprisin a bypass; a valve in the by-pass dividing the interior thereof into two chambers; a group of cooling tubes providing communication between said chambers and with respect to which tubes the by-pass is. centrally disposed; means external" to the radiator for operating said valve so as to control at will the quantity of circulation water which passes, through said by-pass from one chamber directly to the other and thereby varythe amount of water passing through said tubes; and a tank external to the tubes and with which all of them' communicate, said tank having separate outlets for discharging steam and water from. the tubes, the steam' outlet having a check valve.
