復動圧縮機のアンローダ構造。 The unloader piston is slidably guided in the cylinder head, and an O-ring is installed to seal between the chamber on the head side of the unloader piston, where the pressure for operating the unloader piston is introduced, and the suction chamber side in the cylinder head. In an unloader structure for a reciprocating compressor having an unloader mechanism of a suction valve open type provided in the head, the unloader piston can be smoothly operated on either the outer periphery of the unloader piston or the inner periphery of the cylinder head. An unloader structure for a reciprocating compressor, characterized in that a smooth operating member is provided for the purpose of smooth operation.
