Claims

[Claims for Utility Model Registration] 1. An injection passage is opened in a stopper that receives a suction valve during the suction stroke of a reciprocating compressor, and the opening of the injection passage is closed in the suction valve during the suction stroke, and at the same time In a compressor formed with an injection control section that opens apart from the stopper during a stroke, an elastic body is provided that presses the injection control section toward the opening, and the elasticity of the elastic body is equal to the elasticity of the elastic body during the compression stroke. A compressor characterized by having an opening sized to be open. (2) The compression system according to Claim 1 of the Utility Model Registration Claim, wherein the elastic body is a pressing spring provided between the suction valve part guide groove provided in the valve seat and the injection control part. Machine. 3. The compressor according to claim 1, wherein the elastic body is a leaf spring formed integrally with the suction valve.
