Abstract
A valve arrangement for controlling the flow of fluid from an inlet passage to the cylinder of a reciprocating piston compressor wherein the valve is actuated to the open position by the pressure of the fluid compressed in the cylinder by planned early closing of the discharge valve as the piston approaches its top dead center position; actuation of the inlet valve to the closed position being effected at the desired time by operation of a cam and valve closing spring.
