ABSTRACT:
A lubrication system for a compressor unit includes a deflector depending from the inner wall of the compressor housing for directing the oil on the inner wall through a passageway of the front housing into the shaft seal cavity. A flange member extends from the depended end of the deflector along the inner wall of the compressor housing to prevent the oil flow directed to the shaft seal cavity from leaking into the interior of the compressor housing. A balance hole that permits a blow-by refrigerant gas to flow from the crank chamber into the suction chamber is formed in the cylinder block near the center thereof so that oil in the crank chamber is prevented from flowing into the balance hole. The compressor may also include a wobble plate supported by a bearing ball. A seat of the bearing ball is provided with an oil passageway which communicates with a crank chamber so that the bearing ball is lubricated.
