Claims

[Scope of utility model registration request]

A valve seat plate having an annular suction hole opening into the cylinder, an annular portion for opening and closing the suction hole, protrusions protruding outward from the annular portion at mutually opposing positions on the outer periphery of the annular portion, and this annular portion. a suction valve provided with a positioning hole provided in a protrusion and installed between the valve seat plate and the cylinder; a valve receiving groove provided in an upper part of the cylinder and accommodating the protrusion of the suction valve; A valve seat plate and a cylinder, or a pin embedded in the valve seat plate or cylinder and fitted into a positioning hole of the suction valve, and the inner circumferential surface of the cylinder and the bottom and side surfaces of the valve receiving groove are mutually aligned. A relief groove is provided in the meeting part adjacent to the meeting part so that when the suction valve is operated, a root part of the projecting part protruding from the outer periphery of the annular part of the suction valve does not come into contact with the meeting part. Reciprocating refrigerant compressor.
