PROBLEM TO BE SOLVED: To provide a reciprocating compressor wherein a gap between a piston at the top-dead center and a valve-seat member is made narrow to improve compression efficiency. SOLUTION: An intake-valve-holding recessed grooved 16 is provided in the valve-seat member 15 in the flat compression-chamber side-surface 15B facing to a retainer 8 of the piston 6. In the intake-valve-holding recessed groove 16, an intake valve 17 and an intake-valve receptor 18 are held. Thus, the compression chamber side-surface 15B of the valve seat member 15 is made almost flat by filling up the intake-valve-holding recessed-groove 16 with the intake valve 17 and the intake-valve receptor 18. The piston 6 can be brought close to the compression-chamber side-surface 15B to narrow the invalid gap G formed between the upper face 8A of the retainer 8 and the compression chamber side-surface 15B. The intake-valve-holding recessed-groove 16 can be narrowed by directly holding the intake valve 17 and the intake-valve receptor 18 in the intake-valve holding recessed-groove 16. Thus, the compression efficiency at the time when the piston is positioned at the top-dead center can be increased. COPYRIGHT: (C)2008,JPO&INPIT
