機。[Claims for Utility Model Registration] (1) An electric element and a compression element are housed in a closed container, and an end bearing of the compression element is provided with a space for temporarily storing refrigerant gas discharged from the compression element. In the rotary compressor, a pit portion is formed around the discharge port of the end bearing, a cover is press-fitted onto the inner peripheral surface of the pit portion to form a small chamber, and the discharge port is inserted into the small chamber. A rotary compressor characterized by an internal valve that opens and closes the air. (2) The cover has a cup-shaped outer shape and is press-fitted into the same circumferential surface of a pit portion formed concentrically or almost concentrically around the discharge port. A rotary compressor according to claim 1 of the utility model registration claim. (3) The rotary compressor according to claim 1 or 2, wherein the end bearing of the compression element is made of a material with low thermal conductivity.
