The solution for this problem has The lOOCly 12 iS als@ plOVded' Will e nnln been found in eliminating the large single ber Of llIlObStlnCted ports 1S, su'iiloient in moving valve element and substituting a lie aggregate. t0 Cere for the maximum pos- 'number of small ports, and cooperating sible flow through the Openings 8 past l) valve elements, each of which need have an VelVeS l0- Tlle Shell v01 Cylinder 19 may be lee extremely small movement, while the aggre- .provided substantially as shown, to extend gate valve port opening will be ampie. for doi'vnwardlyand around the elements 6 and the maximum demand of the pump. l l2 in order to protect the same.
To the end of the tube 5 is secured the In operation: shell or chambered body 6 by threaded en- -Vhen the tube 5 is reciprocated the fol- 110 lowing action takes place: The lower end of this tube, it will be understood is immersed; upon its downward movement, the water passes through the ports 8, the valve elements 10 moving from their seats into the housings 11, due to the force of the inrushing water. The water passes from ports 8 into space 16 thence through ports 18 upwardly in tube 5. lhis action continues during` the downward movement of tube 5. Upon the reverse movement of tube 5, that is, the upward movement of tube 5, the water .Within the tube will normally cooperate with the elements 10 to cause them to seat Von their respective seats 9, so that no water can flow from tube 5 bach to the well. It will be noted that the movement of each element 10 from open to closed position and vice versa, is extremely short and that therefore there is practically no momentum, or shock, or jar upon the reversal of the tube 5, and yet the aggregate of the openings controlled by the valve elements, is such as to permit a comparatively large volume of flow upon the downstrolre of tube 5. As this movement is short and is distributed through a. large number of valve elements, it follows that there is practically no inertia, as of a large body, to overcome and the opening and closing of the ports 8, are, as a result, eX- tremel';7 rapid.
lt happens that, due to the momentum of the column of water traveling up through pipe 5, the water continues to travel upwardly after the movement of pipe 5 is reversed, that is, after it begins to descend. If the reciprocating movements are suliiciently rapid, there may be a continued upward movement of water through pipe 5. The upward strokes therefore tend merely to boost oraccelerate the vupward flow. ln such case, the valve elements open only when the pressure outside the ports 8 is greater than the pressure inside said ports. When these pressures are equalizcd-the valves close bv the action of gravity.
It will be understood however that the action of the valve elements is not necessarily dependent upon a reciprocating movement of the body containing the ports and valve seats with wiich the valve elements cooperate The construction is equally applicable to a stationary structure containing a valve controlled chamber, in which there is a variation of pressure within said chamber. Devices of'this class are described in a. number of patents to Humphrey, for reciprocating column pumps, for example, Patent No. 1,037,009 dated Aug. 27, 1912 and Patent No. 1,243,296 dated Oct. 16, 1917. In these pumps a column of water is made to reciprocate in a stationary play pipe; the initial movement of the outstroke being caused by the expansion of a primary medium. The
momentum of the water column, after the normal expansion of the primary medium, causes a diminution of pressure to the rear of the column which in turn causes the introduction of fresh water through a non-return valve structure. The return stroke of the water column and the force of the momentum thereof is utilized in compressing a fresh primary charge. rEhe rise in pressure resulting from the return stroke also causes the closure of the non-return valve or valves. Vhere the valve comprises a large moving part, considerable time is required to cause the closure, and the force of the moving volume of water also causes considerable shock to the moving parts. It will thus be seen that the construction in accordance with the present invention is admirably adapted for the conditions last above recited, and for overcoming the obiections referred to.
What I claim is 1. In avalve construction, the combination of a shell formation provided with a plurality of apertures extending through the wall thereof, said apertures having valve seats associated therewith, ball valves adapted to cooperate with said seats, and means surrounded by the said shell formation providing housings independently thereof for said ball valves.

In a valve construction, the combination of a conical shell formation provided with a plurality of apertures extending through the wall thereof, said apertures having valve seats associated therewith, ball valves adapted lto cooperate with said seats, and means surrounded by the said shell formation providing housings independently thereof for said ball valves.
3. In a foot valve, the combination of a pairof shells, one positioned within the other, each shell provided with a plurality of ports, the ports of the outer shell provided with valve seats and the inner shell provided with housings for valve elements, and valve elements adapted to move to and from the valve seats.
4. In aV valve construction, the combina.- tion of a pair of shells, one positioned within the other, each shell provided with a plurality of ports, the ports of the outer shell provided with valve seats and the inner shell provided with housings for valve elements, and valve ball elements adapted to move to and from the valve seats. Y
5. In a valve construction, the combination of a pair of shells, one positioned within the other, each shell provided with a plurality of ports, the ports of the outer shell provided'with valvel seats and the inner shell provided with housings for valve elements, valve elements adapted to move to and from, the valve seats, and means for assembling the shells to secure proper register between the respective housings and valve seats.
6. ln a valve construction, the combination of a pair of ohambered formations one formation projecting into the other, each provided with a plurality of ports, the ports of one formation registering substantially with the ports of the other formation, one formation provided With valve seats surrounding its ports, the other formation provided With valve housings Communicating with its ports, and valve ball elements movable in said housings to and from Said valve seats.
7. In a reciprocating valve structure, the
combination of a pair of ohamloered forma- 15 tions one formation projecting into the other, each provided with a plurality of ports, the ports of one formation registering substantially with the ports of the other formation, one formation provided with valve seats surrounding its ports, the other formation provided With valve housings inclined to the horizontal and communicating Withits ports, and valve ball elements movable in said the structure, to and from said valve seats.
