ABSTRACT:
A hermetic two stage rotary compressor having a housing with a stationary shaft fixedly mounted in the housing. A motor having a rotor and a stator is mounted in the housing with the rotor being rotatably mounted on the shaft. A pair of compression mechanisms are rotatably mounted on the shaft with one compression mechanism being located adjacent a first end of the rotor, and one compression mechanism being located adjacent a second end of the rotor. The compression mechanisms are operatively associated with the rotor such that rotation of the rotor drives the compression mechanisms. A fluid flow path is defined in the compressor including a plurality of longitudinal bores formed in the stationary shaft. A mounting assembly is attached to the housing so as to mount the compressor in either a substantially horizontal or vertical orientation. The pump is positioned so as to be at least partially immersed in an oil sump in the housing when the compressor in either orientation.
