Abstract: 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 c

Abstract: 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.
