Claims

[Scope of utility model registration request]

An upper bearing and a lower bearing, in which an electric element and a compression element driven by the electric element are housed in a closed container, and the compression element closes two cylinders and the open ends of these cylinders via a partition plate;
It is equipped with a rolling piston that is rotatably fitted to the eccentric part of the crankshaft supported by both bearings, and a vane that comes into contact with the outer periphery of these rolling pistons.
In the multi-cylinder rotary compressor with a cylinder deactivation mechanism, which has two suction pipes that independently guide refrigerant into the two cylinders, and one of the suction pipes is equipped with a valve that controls opening and closing of the suction pipe, the bearing A multi-cylinder rotary compressor characterized by having an oil supply path that guides lubricating oil from the inner peripheral surface to the vane on the idle cylinder side.
