ABSTRACT:
In order to continuously supply lubricant to compressor bearings independent of attitude, and under varying gravitational forces, an oil supply system (10) includes an oil sump (14), a pump (22), and a suction tube (24). The oil sump (14) is defined at least in part by a pair of intersecting sump walls (16, 18) each of which may comprise a primary wall dependent upon instantaneous compressor attitude. The pump (22) is adapted to supply the compressor with oil (20) while at the same time removing gases from the oil (20) and expelling the removed gases into the oil sump (14). Additionally, the suction tube extends from the pump to a strategic point within the oil sump (14) for drawing oil (20) from the oil sump (14) to the pump (22) in a manner assisting in priming and repriming during brief interruptions in the flow of oil (20) from the oil sump (14).
