ROTARY VANE COMPRESSOR

摘要

Disclosed is a rotary vane compressor provided with a cylinder chamber having an elliptically-shaped inner wall, a rotor rotatably disposed within the cylinder chamber, vanes retained by the rotor such that the vanes are brought into contact with the inner wall of the cylinder chamber in association with the rotation of the rotor, vane grooves provided in the rotor such that the vane grooves are offset from radial lines, which pass through the center of rotation of the rotor, to the reverse rotation direction of the rotor , and a controller for controlling the rotation of the rotor. The controller rotates the rotor in reverse for a predetermined period of time upon activation of the compressor. Thus, the vanes can be reliably projected from the vane grooves, and chattering can be prevented without providing another member. Further, the vanes can be easily machined and produced at a low cost.
