A positive displacement scroll type apparatus having first and second scrolls with interfitting vanes defining an interface which includes at least one close pocket adapted to move fluid from an inlet to an outlet. The outlet is located in one of the scrolls and is subjected to centrifugal force during operation of the compressor and this in turn causes the separation of lubricant from the compressed fluid by such centrifugal force. A lubricant collector is located at the outlet to prevent the lubricant from entering the remainder of a system with which the compressor may be associated.

A scroll compressor comprising: first and second scrolls having interfitting vanes defining a pumping interface including a movable fluid containing pocket; means for moving one of said scrolls in a closed, non-linear path relative to the other to cause said pocket to move along said interface; a radially inner outlet partially in at least one of said scrolls and opening to said interface; a radially outer inlet opening to said interface; an open conduit within said one scroll extending from said outlet to said interface remote from said outlet; and means associated with said outlet for inducing rotary motion in a fluid therein to cause centrifugal separation of lubricant in the fluid from the fluid in the vicinity of said conduit.
