摘要： The inclination angle of the wobble plate in a wobble plate type compressor is changed to obtain a discharge capacity in accordance with a cooling load. A spring is provided to adjust the inclination angle of the wobble plate in cooperation with the pressure force acting upon the pistons connected to the wobble plate, and thus the pressure in the suction chamber corresponding to the temperature of the exhausted air is kept at a constant level. That is, the temperature of the exhausted air is kept at a constant level suitable for maintaining a desired cooling condition in a vehicle.
