Abstract: An oil lubrication system for a multi-stage compressor separates oil from a refrigerant at an intermediate pressure following the first stage of compression and then routes the separated oil at the intermediate pressure to the compressor suction cavity bearings at the intermediate pressure, thus avoiding further compression of oil in subsequent stages of compression. The efficiency of the multi-stage compressor can be increased by not raising the pressure of the oil through the subsequent stages of compression.

Abstract: A scroll compressor includes one or more stage of compression disposed within a compressor housing. One or more of the stages includes a stationary scroll member including a base and a generally spiral wrap extending from the base of the stationary scroll member. One or more of the stages further includes an orbiting, scroll member including a substantially circular base and a substantially spiral wrap extending from the base of the orbiting scroll member. A coupling is disposed between the first scroll member base and the second scroll member base and in surrounding relationship to the first and second scroll member spiral wraps. At least one stabilizing pad is disposed between the first scroll member base and the second scroll member base and in axial thrust force relationship with the coupling to at least partially prevent tipping of the second scroll member.
