ABSTRACT:
A refrigeration compressor is disclosed which incorporates an improved lubrication system to insure adequate lubrication to all bearings via a single elongated axial offset passage provided in the crankshaft. The lubrication system also incorporates a passage arrangement which serves to vent any refrigerant gases which may be encountered as well as to prevent priming of the vent passage which could result in transfer of lubricant into the motor compartment.
