摘要： A variable wobble plate type compressor with a variable angle non-rotary wobble plate, having a suction chamber for a refrigerant before compression, a discharge chamber for a compressed refrigerant, compressing cylinder bores, pistons reciprocated by the wobble plate within the cylinder bores for compressing the refrigerant, a crankcase having a chamber to receive therein a drive and a wobble plate mechanism connected to the pistons to cause the reciprocating motion of the pistons and capable of changing the wobble angle thereof, a first passageway closably opened so as to apply a high discharge gas pressure of the discharge chamber to the drive and wobble plate mechanism within the crankcase chamber, a solenoid-operated plunger valve for controlling an introduction of a high pressure refrigerant gas from the discharge chamber into a high pressure chamber arranged in a part of the first passageway in response to a change in a cooling load, and a second passageway providing a fluid communication between the crankcase chamber and the suction chamber, a spool valve urged by a spring toward a first position opening the second passageway to thereby permit evacuation of a high pressure gas from the crankcase chamber to the suction chamber while the solenoid-operated plunger valve stops the introduction of the high pressure refrigerant gas into the high pressure chamber of the first passageway, and moved toward a second position closing the second passageway in association with the operation of the solenoid valve for operating the first passageway and introducing the high pressure refrigerant into the high pressure chamber.

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.
