Claims (1)

[Claims for Utility Model Registration] (1) In a reciprocating refrigerant compressor, there is a valve mechanism section that includes a suction valve and a discharge valve, and a valve mechanism section that is attached to the upper part of this valve mechanism section and forms a low pressure chamber and a high pressure chamber. A cylinder cover, a displacement control piston that is housed in the low pressure chamber side of the cylinder cover and that restricts the intake valve from being open during capacity control, and a displacement control piston that controls the high pressure gas that is the operating source of this capacity control piston. A solenoid valve for controlling the capacity is installed at a predetermined position between the small diameter part of the piston for controlling the capacity and the cylinder cover, and prevents the high pressure gas from leaking to the low pressure side without interfering with the operation of the piston. A refrigerant compressor characterized by being equipped with a sealing mechanism to prevent (2) The refrigerant compressor according to claim 1, wherein the sealing mechanism includes an O-ring, an O-ring receiver, and a locking member.
