冷媒圧縮機。[Scope of Claim for Utility Model Registration] (1) An electric element and a rotary compression element are housed in a sealed case, and the suction passage of the compressor compresses gas sucked in from outside the case and discharges it outside the case. A rotary refrigerant characterized in that a check valve is provided, and a high-pressure control valve is further provided in the discharge passage section, which opens and closes based on the difference between the spring force biasing the valve body and the force due to the rear pressure of the vane of the compression mechanism. compressor. (2) The high-pressure control valve houses a slider valve body having a gas passage therein and a spring that biases the slider valve body, and has a discharge passage leading to the outside of the sealed case, 2. The rotary refrigerant compressor according to claim 1, wherein the gas passage and the discharge passage communicate with each other to form a gas discharge passage when operated. (3) Claim 1 of the Utility Model Registration Claim characterized in that the housing chamber for the spring that biases the valve body and the inner space of the rolling piston of the compression element are communicated through a hole provided in the bearing or the like. rotary refrigerant compressor.
