In a reciprocating compressor, the separator plate separating the suction and discharge plenums acts as a spring relative to the valve plate assembly. Under liquid slugging conditions the valve plate moves against the biasing force of the separator plate to establish a relief passage between the piston cylinder and the suction plenum.

Separator and biasing plate

A reciprocating compressor includes a conduit to communicate a first portion operating at compressor suction pressure with a second portion of the compressor operating at compressor discharge pressure. A valve responsive to the temperature of the fluid compressed by the operation of the compressor is provided to control the flow of the fluid through the conduit. The valve is in a normally open position to permit flow of fluid through the conduit when the temperature of the fluid is at a relatively low level. As the compressor continues to operate, the temperature level of the fluid increases whereby the valve is placed in a closed position to terminate the flow of fluid through the conduit.
