Claims

[Scope of utility model registration request]

In the rotary compressor, the partition plate whose end is in sliding contact with the outer circumferential surface of the rolling piston that is in sliding contact with the inner circumferential surface of the cylindrical cylinder chamber is fitted and supported in a groove provided in the cylinder such that it can freely move in and out of the cylinder chamber, A rotary compressor characterized in that a passage area of an oil supply through hole extending axially on the radially outer side of the groove toward the upper surface of the cylinder is smaller than a passage area thereof toward the lower surface.
