ABSTRACT:
A valve arrangement for a compressor, particularly a compressor for compressing refrigerant, in which a compressor is provided with ports distributed circumferentially about the axis of the piston and cylinder of the compressor and with a valve member in the form of a ring adjacent the ports for controlling the ports. Associated with the valve ring is a spring in the form of a wave washer urging the ring toward the valve ports. The ring forming the movable member of the valving arrangement and the wave washer serving as a spring require the minimum in space and have long life because the fatigue factor in respect of both is quite small.
