ABSTRACT:
A compressor valve for use in a piston type compressor having an annular tapered shaped valve element spring-urged into a valve seat formed between the intake suction side of the valve body and an annular passage formed behind the seat which communicates with a central outlet passage formed in the exhaust side of the valve body. The piston in a compressor adapted to force fluid back through a plurality of inlet passages communicating with an annular passage which communicates with outlets in the valve body, said plurality of inlet passages being sealed by a spring-urged annular valve element. The piston sucks air into the inlet urging the first annular valve element off its seat to allow flow of the gas in through the outlet passage into the piston chamber. The piston then forces the air through the plurality of inlet passages urging the second valve element off its seat such that the gas flows around both the inner and outer sides of the valve element to the outlet of the compressor.
