Oil separation structure in compressor

摘要

A muffler forming member defines a muffler chamber. Refrigerant discharged from a cylinder bore is sent to the muffler chamber. The muffler forming member is coupled to a circumferential surface of a housing of a compressor. An oil separation chamber is defined in a discharge pressure zone of the compressor. The oil separation chamber separates the oil from the refrigerant discharged from the cylinder bore. The oil separation chamber extends into both the muffler forming member and the housing. The oil separation chamber has a refrigerant inlet through which the refrigerant flows into the oil separation chamber. The refrigerant inlet is formed in the muffler forming member. Therefore, the oil separation chamber is prolonged in the direction from the muffler forming member toward the housing, thereby improving the oil separation performance.
