。[Claims for Utility Model Registration] (1) A cylinder, a rolling piston that is fitted onto an eccentric portion of a rotating shaft and rotates eccentrically while abutting the inner circumferential surface of the cylinder, and is supported to be slidable in the radial direction on the cylinder. In a rotary compressor, the rotary compressor is equipped with a vane that contacts the outer circumferential surface of the piston, and performs a compression operation by eccentric rotation of the piston. A hole is provided to allow compressed gas to flow backwards.
A slider is fitted into the hole, a back pressure control flow path is connected to the back side of the slider in the hole, and the volume on the inner circumferential side of the cylinder from the slider in the hole is increased or decreased by movement of the slider through back pressure control. Characteristic rotary compressor. (2) The rotary compressor according to claim 1, wherein the holes and the slider are arranged continuously over a required section in the inner circumferential direction of the cylinder.
