とを特徴とするベーン型回転圧縮機。 A cam ring is installed between the front plate and the rear plate, and a rotor that slidably accommodates the vanes and has a substantially radial rotor slit with a back pressure passage is provided in the cam ring, and the rotor axis of the rotor is connected to both plates. A working chamber is defined by both plates, the cam surface on the inner circumference of the cam ring, and the outer circumferential surface of the rotor, and a suction hole and a discharge hole for refrigerant gas are provided in this working chamber. and make the vane appear from the lotus slit,
A vane-type rotary compressor that sucks refrigerant gas into the working chamber while sliding one end of the vane against the cam surface of the working chamber, compresses it, and then discharges it. A constriction part is provided between the high pressure side of the lubricating oil system that circulates through the rotor and lubricates each rotating part and the back pressure passage of the rotor, and the lubricating oil is guided to the back pressure passage through the constriction part, and and a plate, one end of which opens near the discharge hole of the working chamber, the other end of which communicates with the back pressure passage of the rotor, and does not have a constriction part. A vane type rotary compressor characterized in that another passage is provided in the rear plate, and this passage is opened and closed by a control valve according to the pressure difference between discharge pressure and suction pressure.
