ABSTRACT:
There is disclosed in a refrigerant compressor whose crankcase is vented to compressor suction, a passive lubrication system having a lubrication-vent path arrangement which vents the crankcase while also assuring lubrication of the compressor's critical bearing surfaces using oil entrained in the refrigerant and wherein centrifugal action is utilized to always maintain some amount of oil in the crankcase for assured lubrication of the critical bearing surfaces under all operating conditions while also minimizing the amount of oil permitted to circulate in the refrigerant circuit for improved air conditioning performance.
