ABSTRACT:
A rotary blade air conditioner compressor is provided which includes a compressor housing having a cylindrical chamber. Chamber covers are mounted to respective ends of the cylindrical chamber. A reservoir is fluidly connected to an outlet and an inlet of the cylindrical chamber. A drive shaft is eccentrically mounted within the cylindrical chamber, with a rotor mounted on the drive shaft which is axially movable along the drive shaft. A plurality of radial slots are formed in the rotor which receive blade members that move radially in the slots to continuously contact the inner wall of the cylindrical chamber for expelling a mixture of gas and oil from the chamber. The gas and oil mixture comes from the reservoir and is supplied through a conduit to each end of the cylindrical chamber to axially displace the rotor with respect to the chamber covers.
