Horizontal two stage rotary compressor

A hermetic rotary compressor, comprising:

• a housing;
• a stationary shaft fixedly mounted in said housing;
• a motor mounted in said housing, said motor having a rotor and a stator, said rotor having a first and second end and being rotatably mounted on said shaft;
• first and second compression mechanisms rotatably mounted on said shaft, said first compression mechanism located adjacent said first end of said rotor, and said second compression mechanism located adjacent said second end of said rotor, said compression mechanisms operatively engaged with said rotor, whereby rotation of said rotor drives said compression mechanisms about said stationary shaft;
• and
• two eccentrics integrally formed on said stationary shaft, said first and second compression mechanisms each containing a said eccentric, each said compression mechanism having a compression chamber, the volume of which being varied with the angular position of said compression mechanism relative to its said eccentric.

A hermetic rotary compressor, comprising:

• a housing;
• a stationary shaft fixedly mounted in said housing and having first and second ends;
• a motor mounted in a motor chamber defined in said housing, said motor having a stator and a rotor, said rotor having opposite ends and rotatably mounted about said stationary shaft;
• a first and a second stage compression mechanism, said compression mechanisms fixed to opposite ends of said rotor;
• a first longitudinal bore extending from said first end of said stationary shaft to said first stage compression mechanism, said first longitudinal bore in fluid communication with said first stage compression mechanism via a first radial passage;
• and
• a second radial passage extending between said first stage compression mechanism and a second longitudinal bore formed in said stationary shaft, said second longitudinal bore having a discharge port in fluid communication said motor chamber;
• said motor chamber and said second stage compression mechanism in fluid communication, said second stage compression mechanism in fluid communication with a third longitudinal bore formed in said stationary shaft via a third radial passage, said third longitudinal bore extending from said second stage compression mechanism to said second end of said stationary shaft, compressed refrigerant exhausted from said compressor through said stationary shaft second end.

A hermetic rotary compressor, comprising:

• a housing having an outer surface;
• an oil sump defined in said housing;
• a stationary shaft fixedly mounted in said housing;
• a motor mounted in said housing, said motor having a stator and a rotor, said rotor rotatably mounted about said shaft;
• first and second compression mechanisms rotatably mounted at opposite ends of said rotor and operatively engaged with said rotor;
• and
• a mounting plate attached to said outer surface of said housing, said compressor mounted in one of a substantially horizontal and vertical orientation.
