摘要： A compressor having a housing formed by joining a plurality of housing components. A plurality of muffler elements are formed integrally with the housing components along the periphery of the housing. A muffler chamber is defined in the housing by coupling the housing components to one another. A large volume chamber and a small volume chamber are defined in the muffler chamber and connected to each other. An inlet is provided in at least one of the muffler elements for drawing the gas in the discharge chamber into the large volume chamber. An outlet is provided in the muffler elements for discharging the gas in the small volume chamber into the external circuit. The arrangement and construction of the housing is such that the pressure pulses in the discharge gas are reduced, and thus vibration and noise are reduced.

摘要： A swash plate type compressor having a pair of axially combined front and rear cylinder blocks forming therein a plurality of cylinder bores and a swash plate chamber into which an oil-contained refrigerant is introduced from an air-conditioning circuit, a drive shaft centrally rotatably mounted in the combined cylinder block, a swash plate having sliding contact faces oblique to an axis of the drive shaft, and supported on the drive shaft so that the swash plate is rotated within the swash plate chamber, compressing double-headed pistons slidably fitted in the cylinder bores, shoes intervened between the swash plate and the pistons for causing reciprocating motions of the pistons in response to rotating motion of the swash plate, and a shoe and swash plate lubricator for constantly supplying a lubricating oil component contained in the refrigerant gas between the swash plate and the shoes. The shoe and swash plate lubricator is formed by recessed portions arranged in a determined part of the sliding contact faces of the swash plate, and captures and retains the oil-contained refrigerant at a position adjacent to the circularly extending flat path of the swash plate in sliding contact with the shoes while the swash plate is rotating within the swash plate chamber, to constantly supply the oil-contained refrigerant to each of the shoes and the swash plate per se.
