Abstract
A rotary vane machine includes a stator housing having an inner surface defining a stator chamber and inlet and outlet ports, a substantially cylindrical rotor rotatably mounted within the chamber, a crank axle rotatably mounted within the chamber and including a plurality of crank pins offset from an axis of rotation of the crank axle, and a plurality of vane pairs. Each vane pair includes two opposing vane members slidably received in the rotor and means for connecting the opposing vane members together and rotatably connecting the vane pair to a different one of the crank pins. Rotation of the crank axle causes the vane pairs to rotate and urge against the rotor, thereby rotating the rotor.
