PROBLEM TO BE SOLVED: To improve valve opening and closing accuracy by disposing a control valve main body changing an inclined angle of a swash plate on the side of a rear housing and providing low temperature coolant gas introducing space which is communicated with an inlet pressure area of a compressor between a solenoid housing and a rear housing. SOLUTION: The change of discharge capacity of a variable displacement compressor 1 is performed by adjusting the opening of a spherical valve element 126 of a control valve 100 interposed in a coolant gas path communicating a discharge pressure area and a crank chamber 8 by energizing force of a solenoid incorporated into the control valve 100 and changing an inclined angle of a swash plate 10 within the crank chamber 8. At this time, the control vale 100 is buried on the side of a rear housing 3 of the compressor 1, low temperature coolant gas introducing space which is communicated with an inlet pressure area of the compressor 1 is formed between a solenoid housing and the rear housing 3 of the control valve 100 and an inlet port is communicated. As a result, the control valve 100 is cooled by low temperature coolant gas from the side of a suction chamber 13 and overheat of the solenoid is prevented. |
