Abstract

A hermetic compressor comprises a housing having an oil containing sump, a motor and a compression mechanism in the housing, a bearing in a stationary frame and a drive shaft supported by the bearing. The drive shaft operatively couples the motor and the compression mechanism and a longitudinal oil supply passageway extends through the drive shaft in fluid communication with the sump. A chamber, located at a first end of the drive shaft, is in fluid communication with the oil supply passageway. Oil from the sump is provided to the chamber through the oil supply passageway. An oil return passageway extends from the chamber to an annulus formed between the bearing and the drive shaft and extends at least partially through the stationary frame. Lubricating oil is provided to the annulus through the oil return passageway so that the bearing and drive shaft interface is lubricated.
