回転圧縮機。 An oil supply path that opens and closes the oil in the oil reservoir in the discharge chamber by a check valve that opens when the differential pressure between gas discharge pressure and suction pressure is below a set value, and closes when it is above the set value. In the vane type rotary compressor, the oil is supplied to the back pressure chamber of the vane receiving hole through the check valve. A vane-type rotary compressor characterized by being provided with a throttling mechanism that introduces the compressed air into the vane receiving hole side.
