コンプレツサ。 A drive swash plate 13 is connected to the drive shaft 11 in a variable inclination angle, and a cylinder 25 is slidably connected to the drive swash plate 13 and extends in the direction of the drive shaft 11.
Due to a change in the differential pressure between the internal pressure of the crank chamber 12 housing the non-rotating wobble plate 16 to which the piston 23 that can reciprocate is connected and the internal pressure of the compression chamber 26 formed on the front surface of the piston 23. By changing the inclination angle of the wobble plate 16, the compression chamber 2 is
6, the crank chamber 12 is formed with a suction pressure communication port 41 for introducing compressor suction pressure and a discharge pressure communication port 40 for introducing compressor discharge pressure. Control valves 36 and 39 for controlling the opening degrees of both communication ports 40 and 41 using the compressor suction pressure are provided in both communication ports 40 and 41, and the suction pressure communication port 41
The variable capacity swash plate type is characterized in that a bypass valve 54 is provided in the communication path between the crank chamber 12 and the crank chamber 12 to release the internal pressure to the compressor suction side when the internal pressure of the crank chamber 12 exceeds a predetermined pressure. Compressa.
