ABSTRACT:
A piston type compressor having a cylinder block in which a plurality of compression chambers permitting a plurality of pistons to be reciprocated so as to compress a refrigerant gas pumped from a suction chamber formed in an end housing into the compression chambers through suction ports of a valve plate, openably closed by a suction valve mechanism with a plurality of suction reed valves, and to discharge the compressed refrigerant gas from the compression chambers into a discharge chamber formed in the end housing through discharge ports of the valve plate, are openably closed by a discharge valve mechanism having a plurality of discharge reed valves. The suction and discharge reed valves of the suction and discharge valve mechanisms are prevented from undergoing complicated and irregular vibrations by an asymmetrical arrangement of the suction and discharge ports of the valve plate, or by provision of asymmetrical through-openings to adjust mechanical flexibility to the suction and discharge reed valves for both reed valves.
