ABSTRACT:
A rotary compressor for compressing fluid. A housing having a cylindrical internal cavity is provided with vanes and delivery ports. A rotor is rotatably mounted in the housing. The rotor has a portion for making a sealing contact with the inner peripheral surface of the housing. The rotor has a suction chamber formed therein. The number of the vanes is greater by 1 (one) than the number of the sealing contacts between the rotor and the inner peripheral surface of the housing. At least one suction port is formed through the wall of the rotor, so that the fluid in the suction chamber may be sucked into the working chamber defined by the vanes, rotor and the housing. The suction port is so located that, when a working chamber has been expanded to its maximum volume, the suction port is positioned between the vane located at the leading side of the working chamber as viewed in the direction or rotation of the rotor and the sealing portion closer to the vane. The fluid compressed in the working chamber is delivered to the outside of the housing through the delivery ports.
