Claims

[Scope of utility model registration request]

A rotating shaft, a rotor rotated via the rotating shaft, a large number of vanes attached to the rotor so as to be freely protrusive and retractable in a substantially radial direction, a cam ring that accommodates the rotor with the vanes attached, and a cam ring that holds the cam ring in place. The cam ring has a pair of side plates that form a pump chamber on the inner periphery of the cam ring, and a housing that accommodates the side plate or rotor, and when the rotor is rotated, the vanes attached to the rotor move into the cam ring. The vanes slide while being pressed against the inner circumferential surface of the vanes, and the volume change between the vanes at that time introduces the working gas into the pump chamber through the suction passage, pressurizes it, and discharges it to the outside through the discharge passage. Oil, etc. in the oil reservoir connected to the discharge passage is supplied to the vane receiver during startup through an oil supply passage that has a check valve that opens when the differential pressure between the gas discharge pressure and suction pressure is below a set value, and closes when it exceeds the set value. In a vane-type rotary compressor that supplies water directly to the bottom of the hole, the sliding surface of the one side plate that contacts the rotor is located near a small arc where the outer circumferential surface of the rotor approaches the inner circumferential surface of the cam ring. A supercharging groove that communicates only with the bottom of the vane receiving hole is provided, and the oil supplied through the oil supply passage is guided only to the bottom of the vane receiving hole near the small arc through the supply groove. A vane type rotary compressor characterized by:
