摘要： In a structure for mounting a filter in a compressor, a mounting member is connected to the filter. A receiving hole is formed in a housing of the compressor for receiving therein the mounting member. A first fitting portion is formed on an inner circumferential surface of a holding portion of the filter. A second fitting portion is formed on an outer circumferential surface of the mounting member for having fitting relation to the first fitting portion for an overlap distance in a radial direction of the receiving hole. When the mounting member is received in the receiving hole with the fitting relation, the filter is disposed in a fluid passage of the housing. A clearance having a dimension is formed between an outer circumferential surface of the holding portion and an inner circumferential surface of the receiving hole. Minimum value of the dimension is smaller than the overlap distance.

摘要： A compressor has a discharge passage, an oil separation mechanism, an oil supply passage, and a valve mechanism. The oil supply passage supplies the separated lubrication oil into an oil recovery region. The valve mechanism is formed in the oil supply passage and includes a valve chamber, a spool and an urging member. The spool separates the valve chamber into a first pressure sensing chamber and a second pressure sensing chamber. The amount of the lubrication oil supplied to the oil recovery region is adjusted in such a manner that as the pressure differential between the first and the second pressure sensing chambers increases, the spool slides in the valve chamber and the opening degree of the oil supply passage increases to the maximum and then decreases, and that when the compressor is stopped, the opening degree of the oil supply passage is minimized by the urging force of the urging member.

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.
