リーコンプレツサ。[Scope of Claim for Utility Model Registration] (1) In a rotary compressor in which a cylinder is provided with a release port that returns refrigerant in the process of being compressed to the suction side, and a check valve is provided in the release port, the inlet side of the release port and A rotary compressor characterized in that a plunger valve is provided between the check valve and the plunger valve that shuts off the release port in response to pressure applied to the release port. (2) A plunger valve has a valve chamber formed in the release port so as to intersect with the release port, a valve body that is biased toward one end of the valve chamber that opens and closes the release port, and a valve body that opens and closes the release port. The rotary compressor according to claim 1, wherein one end of the rotary compressor and the valve body facing the valve body are communicated with the outlet side of the release port through a passage.
