Abstract:
1. A rotary vane compressor comprising: a cylinder chamber having an ellipsoidal inner wall shape; a rotor rotatably provided in the cylinder chamber; a vane held in the rotor so as to contact with an inner wall surface of the cylinder chamber along with a rotation of the rotor; a vane slot provided on the rotor and offset on a reverse rotational side of the rotor from a radial line passing over a rotational center of the rotor; and a controller configured to control a rotation of the rotor, and determine whether the vane protrudes from the vane slot, wherein when the controller determines that the vane does not protrude from the vane slot, the controller is configured to reversely rotate the rotor at a slower speed than a normal rotational speed for a predetermined time upon activating the compressor.
