Abstract

A vapor compression system including a compressor, a condenser, an expansion device and an evaporator connected in a closed refrigerant loop. The compressor has a high pressure discharge, a low pressure inlet and a port having an intermediate pressure greater than the low pressure inlet and less than the high pressure discharge. A fluid moving device is arranged and positioned to receive intermediate pressure refrigerant and oil mixture from the port to urge flow of a mixture of oil and refrigerant from the evaporator to the low pressure inlet of the compressor.
