ABSTRACT:
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.
