  • Valve for piston compressors and pumps
    Patent number: 4184818
    Abstract: The present invention relates to piston compressors and pumps and more particularly it relates to the valves used in these compressors. The valve according to the invention comprises a seat with gas passages and a plate with a Tee profile in cross section. The vertical element of said profile is located at the side of the seat while the horizontal element has closing portions at the ends, said portions contacting the seat on closing of the valve. This improves the operational reliability of the valve, reduces its gas-dynamic resistance and simplifies the alignment of the valve plate.
