VALVE Filed Dec. 22. 1931 ATTORN EY INVENTOR F. W. EYLQRJ.

BY wwM WITNESSES: I m M Patented Nov. 5, 1935 UNITED STATES PATENT OFFICE a claims. (or. est-231) My invention relates to compressors, and particularly to intake and discharge valves for compressors.

It is an object of my invention to provide compressor intake and discharge valves by means oi a plate and two resilient sheet members having movable flaps which are placed adjacent to the plate, one on each side thereof.

It is another objectv of my' invention to provide a compressor valve such as described above so that the aforesaid valve sheets placed on each side of the valve plate are identical, and, therefore, interchangeable, so that only one stamping die is necessary and so that only one kind of valve sheet it need be kept in stock. It is a further object of my invention to provide intake and discharge valves for a compressor which have few moving parts, and which are of exceptionally long life relative to existing valves the low pressure side of the compressor.

20 particularly when utilized in high-speed compressors.

The features of the invention which I believe tobe new are particularly pointed out in the appended claims. For a full understanding of the t principles of the invention and the best mode of applying the same, reference may be had to the accompanying drawing, in which,

Fig. 1 is a front elevational view of a portion of an assembled compressor containing an em- 30 bodiment of my invention. v

Fig. 2 is a top plan view of the compressor shown in Fig. 1,

Fig. 3 is a sectional view, taken on line m-m of Fig. 2, illustrating a portion of a compressor 35 embodying my invention, and

Fig. 4 is an exploded perspective view of the compressor shown in Fig. 1, showing in the order of assembly the various parts of the compressor which are utilized in my invention.

40 In order to accomplish the objects of my invention, a compressor is essentially constructed in the following'manner. A valve plate is disposed between the compressor head and cylinder, and is provided with intake and discharge ports.

45 Two interchangeableresilient sheets having resilient flaps and port apertures-cut .therein are disposed-adjacent to the valve plate, one on each side thereof, with the resilient flaps and port apertures properly arranged with respect to the 50 inlet and discharge ports of the valve plate, so that the ports of the valve plate which connect with the high and low pressure sides of the compressor are opened or closed in response to conditions within the compressor, namely, suction or 5 discharge of the compressor. a

The improved form of the compressor head and valve plate, and the preferred form of valve discs which are utilized in my invention are described and claimed in the application of Frank Conrad and Christian Aalborg, for compressors, Serial 5 No. 581,260, filed December 15, 1931, and assigned to the assignee of the present application.

Referring specifically to the drawing for a detailed description of my invention, numeral 2 designates generally a compressor comprising a cylinder 3, a piston 6, a valve plate 5, a head i, intake conduits 9 and a discharge conduit H.

The valve plate 5 comprises a substantially flat preferably metallic plate provided with lateral intake passageways E3, to which are connected it the intake conduits 9. An intake port i5, extend- -ng from the lower surface of the valve plate 5 to a point about halfway through the plate, connects with the intake passageways it to form A dis- 2a charge port it extends completely through'the valveplate 5. Screw holes ii are provided in the plate 5 to facilitate assembly with the other parts of the compressor.'

An upper valve disc 23 and alower valve disc 26 are disposed on each side of the valve plate 5 and are provided with resilient flaps 25 and 26, respectively, and port apertures 2i and 28, respectively. The discs 23 and 2d are identical and, therefore, interchangeable. The directions of 30 the flaps 25 and 26 are reversed in assembly, as shown in Figs. 2 and i, and the port aperture 2? in the upper valve disc 23 is not utilized in this embodiment oi my invention. The flaps 25 and 26 are so disposed as to overlap the ports ill and i5, respectively, when assembled.

Rivet holes 33, it, it, and it are provided in the stop member 2%, the upper disc 23, the valve plate 5 and the lower disc 26, respectively, and rivets 35 hold the above members together. above members are assembled before being disposed in the compressor i.

The head '5 of the compressor i is provided with a hollow raised portion at on the top thereof for receiving compressed gas, and an aperture It is provided in the head i which connects with the discharge conduit ii. The head l and cylinder 3 are provided with tapped holes 3? and 39, respectively, and bolts il extend through holes 3? and 39 as well as through holes ii in the valve plate a. The bolts ti are'utilized to assemble the cylinder t after the resilient discs 23 and 2t and the stop member 29 are attached to the valve plate 5'. The operation of the compressor is as follows:

The 0 on the suction stroke of the piston 4, the flap 26 of the lower valve disc 24 is pulled downwardly because of the partial vacuum present in the cylinder 3 on the suction stroke. Gas, therefore, enters the cylinder -3 through the intake conduits- 9, and passageways l3 and intake port I5 in the valve plate 5. At the same time, the resilient flap 25 of the upper valve disc 23, which overlaps the, discharge port I1, is pulled tightly against the valve plate 5, thus closing the port tightly so that medium is not drawn from the high pressure side of the compressor on its suction stroke.

On the compression stroke of the piston 4, the flap 26 in the lower disc 24, which overlaps the intake port I5, is forced against the valve plate 5 by pressure of the medium being pumped, thus closing'the intake port l5 so that medium is not forced into the low pressure side of the compressor. The medium which is compressed passes through the discharge port I1, raises the flap 25 of the valve disc 23 and passes into the raised portion I of the head 3 and through the aperture in and conduit II in the head 3. The stop member 29 limits the upward movement of the flap 25 of the valve disc 23.

From the foregoing description and drawing, it will be readily seen that I have provided a simfrom the periphery of the plate into one of said i flat surfaces, and sheet valve members lying against said respective flat surfaces, said valve members including portions retained in fixed relation against the flat surfaces and movable flap portions cooperating respectively with said inlet and outlet ports to form inlet and discharge valves, the valve member embodying said inlet' valve having an aperture therein in registry with the outlet port.

2. In a fluid translating device, the combination of a cylinder, 9. cylinder head, a valve plate disposed between the cylinder, and the cylinder head and having fiat surfaces on opposite sides thereof, said valve plate having an inlet port extending from the periphery of said plate into one of said fiat surfaces and an outlet port opening into both of said fiat surfaces, and valve members disposed oneither side of said valve plate, said valve members including portions retained in fixed relation against the fiat surfaces and movable flap portions cooperating respectively with said inlet andoutlet ports to form inlet and discharge valves.
