HORIZONTAL TWO STAGE ROTARY COMPRESSOR

摘要

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 mount ed 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 bei ng located adjacent a second end of the rotor. The compression mechanisms are operative ly 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 t o 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 t he compressor in either orientation.
