RECIPROCATING COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To reduce leaking of a high-pressure refrigerant gas compressed in a cylinder bore from the end face of a cylinder block around the bore and thereby suppress drop of the performance of a compressor resulting from leakage of the refrigerant gas. SOLUTION: This reciprocating compressor is structured so that a gasket 45 as a sealing member is held pinchedly between a cylinder block 10 and a suction valve 44, wherein the gasket 45 is formed from a metal plate 46 and elastic films of rubber 47 and 48 attached to the end faces of the plate 46 and has a ring-shaped bead part 45c as a seal. The bead part 45 surrounds each bore 10a and is contacted by pressure to the front end face of the suction valve 44 over the whole circumference so as to secure a sealing performance for each bore 10a. Around the bore 10a when a refrigerant gas is compressed in it, it is possible to suppress leakage of high pressure refrigerant gas from the gap between the cylinder block 10 and suction valve 44 or around the gap.
