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.
