Abstract:
A reciprocating compressor, comprising:a cylinder assembly wherein a plurality of cylinder bores are arrayed upon a certain circumference;a drive shaft rotatably supported at the center of said cylinder assembly;a cam plate mounted to said drive shaft;a plurality of pistons which reciprocatingly move within said cylinder bores, the rotational force of said drive shaft transmitted as reciprocating motion thereto via said cam plate;at least one cylinder cover provided so as to cover the end of said cylinder assembly, with a generally loop-shaped discharge chamber and a generally loop-shaped suction chamber formed therein in a generally concentric manner;a valve plate provided between said cylinder cover and said cylinder assembly;a plurality of discharge ports bored at certain positions on a certain circumference in said valve plate;a discharge valve formation plate which is introduced between said cylinder cover and said valve plate, integrally forming a plurality of reed discharge valves which open and close said discharge ports;a retainer plate which is introduced between said cylinder cover and said discharge valve formation plate, having a loop-shaped sealing portion which seals the edge of the inner circumferential wall of said discharge chamber formed in said cylinder cover, said retainer plate being integrally formed of a plurality of retainers for restricting the degree of opening of said discharge valves, said retainers radially protruding from the periphery of said loop-shaped sealing portion; andlinking members linking neighboring said retainers one to another.
