ABSTRACT:
A scroll compressor includes a stationary scroll and an orbit scroll for circulating refrigerant. Lubricant is introduced into the refrigerant at an inlet side of the compressor to maintain a seal between the scrolls. Lubricant is separated from the refrigerant within a discharge chamber. A control mechanism varies the flow of lubricant into the refrigerant as a function of a pressure occurring at an outlet side of the scrolls, and also as a function of the amount of lubricant present in the discharge chamber.
