ABSTRACT:
Noise is caused in a piston type compressor having a valve assembly including reed valves (13F, 14F) and a valve plate (10F) when the reed valves close and strike against the valve plate. The present invention provides a piston type compressor having a valve assembly including an elastic member (21F) and a thin valve sheet (20F) between the valve plate (10F) and the reed valves (14F), so that a shock caused by the reed valves striking the valve plate is absorbed, and the elastic member is protected by the thin valve sheet from damage usually caused by the striking thereof by the reed valves.
