Claims

[Scope of utility model registration request]

A cam ring is mounted between the front plate and the carrier plate, and within the cam ring is a rotor having slidable vanes housed in generally radial slits having back pressure passages, and bearing the rotor shaft of the rotor. In a rotary compressor that is supported on each of the plates through a rotor, a vane is moved in and out as the rotor rotates, and one end of the vane is in sliding contact with the inner periphery of the cam ring. In the lubrication system of the lubricating oil that circulates and lubricates each rotating part, a constricted part is provided between the high pressure part side and the back pressure passage of the rotor, the lubricating oil is guided to the back pressure passage through the constricted part, and further The lubricating passage is guided to the low pressure part side through a gap between the rotor side surface and the plate, and another lubrication passage having no throttle passage is provided between the high pressure part side and the back pressure passage of the rotor, A rotary compressor in which this lubricating passage is opened and closed by a control valve depending on the differential pressure between the discharge pressure and suction pressure of lubricating oil.
