ABSTRACT:
In a reciprocating compressor, a piston reciprocates to compress a gas, and the compressed gas communicates with a discharge opening formed in a valve plate to force open a discharge valve apparatus mounted on the valve plate. The discharge valve apparatus includes a discharge valve and a stopper disposed behind the discharge valve. The discharge valve includes a fixing or anchoring portion and a movable portion which is flexibly movable relative to the fixing portion for opening and closing the discharge opening. The stopper limits the opening angle that can be achieved by the movable portion of the valve. The stopper forms a corner that bears against the valve. The corner extends at an oblique angle relative to a longitudinal axis of the valve in order to attenuate vibration in the movement portion of the valve before it reaches the fixing portion, thereby stabilizing the valve.
