Claim:
An inclined plate-type compressor comprising: a cylinder head; a discharge chamber having an annular shape and disposed along an outer circumferential portion of said cylinder head; a suction chamber formed at a central portion of said cylinder head; a valve plate comprising a plurality of discharge ports in communication with said discharge chamber; a discharge valve comprising a plurality of reed valve-type valve bodies disposed in said discharge chamber, each of said valve bodies opening and closing a corresponding one of said discharge ports, each of said valve bodies extending in a circumferential direction of said discharge chamber and oriented along said annular shape of said discharge chamber; a retainer, which regulates an opening degree of a corresponding one of said valve bodies, wherein portions of said retainer at either side of said retainer opposite a tip portion of each of said valve bodies and a retainer root portion of said retainer opposite a valve body root portion of each of said valve bodies remain attached to said head gasket; a head gasket interposed between said valve plate and said cylinder head; a head stepped portion for receiving each of said valve bodies is disposed on an outer circumferential portion of said head gasket; and a communication passage placing a fine annular space, which is formed between said head stepped portion, an outer surface of said discharge valve, and said valve plate, in communication with a lower pressure region of said inclined plate-type compressor, wherein said retainer root portion and said valve body root portion are secured to said valve plate by a seat surface of a threaded portion of a fastening bolt formed on said outer circumferential wall of said cylinder head, and said seat surface is adjacent to the retainer root portion and valve body root portion, and wherein a line extending from a longitudinal axis of the valve body intersects said seat surface.
