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 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.
