Abstract

A refrigeration system includes a compressor having a compressor housing and operable to compress a flow of refrigerant. A pump is operable to provide a flow of oil to the compressor. A portion of the oil mixes with the flow of refrigerant and the remainder of the oil flows into the compressor housing. A valve is movable between an open position and a closed position. When in the closed position, the valve is operable to inhibit the addition of oil above a predetermined level within the housing.
