Claims

[Scope of utility model registration request]

For a closing plate part, a closing plate part is formed at the lower end of a push rod of an unloader mechanism built into the suction passage wall of a reciprocating compressor, and the closing plate part can be tightly engaged with a valve receiver of a valve plate that opens and closes a suction port. A pressure regulator which forms a seat and is interposed in a connecting pipe between the discharge valve mechanism and the compressed air reservoir is connected to the unloader mechanism via a conduit, and when the pressure inside the compressed air reservoir reaches a specified pressure, the push rod A pump loss reduction device for a reciprocating compressor in which a suction port is closed by engaging a closing plate portion with a closing plate seat.
