RECIPROCATING COMPRESSOR

PROBLEM TO BE SOLVED: To reduce noises by arranging a resonance chamber in a valve plate, and providing a pressure introducing part interlocking with suction holes in the resonance chamber. SOLUTION: The tip sides of respective valves in a suction valve 32 block up respective suction holes 31 of a valve plate 6, the tip sides of respective valves in a delivery valve 35 block up respective delivery holes 34 of the valve plate 6, and a retainer 36 is fixed by screw fastening so as to become the same plane as the delivery valve 35. Respective elliptic hole parts bored on the base end sides of the respective valves in the suction valve 32 communicate with the respective delivery holes 34 of the valve plate 6. A resonance chamber 60 having a pressure introducing part 601 opening in the suction holes 31 and being a space part by applying a theory of a Helmholtz resonator is arranged in a valve plate 6 unused part. The resonance chamber 60 vertically symmetrically divides the valve plate 6, and is integrally formed with each other after respectively manufacturing the resonance chambers. The pressure introducing part 601 separates from the center, and the pressure introducing part 601 can be arranged only in one of them.
