Abstract
An air conditioning compressor is equipped with an oil separator for separating high-pressure refrigerant gas and lubrication oil into a gas component and an oil component. The compressor's casing has a barrel portion surrounding an outer portion of the compressor and an enlarged case potion extending from the barrel portion. The enlarged case portion has a discharge chamber disposed between an inner surface of the casing and a rear portion of the compressor for temporarily holding the gas component and the oil component. An oil sump within the discharge chamber is dimensioned to store a sufficient amount of the oil component to suppress an increase in the oil circulation ratio of an air conditioning system while maintaining a sufficient amount of the lubrication oil in the compressor casing to lubricate the compressor.
