Abstract: An oil separator for a fluid compressor is disclosed. The oil separator includes a housing having a generally cylindrical cavity formed therein. A wall is disposed in the cavity to form an inlet side of the cavity and an outlet side of the cavity. A conduit extends through the wall and provides a fluid communication path between the inlet side and the outlet side of the cavity. The inlet side of the cavity facilitates the separation of an oil from a fluid, wherein the separated oil is returned to an oil reservoir formed in the housing, and the fluid is provided substantially free of oil to an associated refrigeration circuit.
