ABSTRACT:
A variable capacity swash plate type compressor having compression chambers formed on one side of the plungers only, and control chambers for controlling the capacity of the compressor provided on the other side of the plungers. The capacity of the compressor is controlled by adjusting the pressure in the control chambers, whereby the inclination of the swash plate is changed because the force exerted on the plunger by the pressure in the control chamber, i.e., the force moving the swash plate, is changed. Therefore, since the volume of the compression chambers is relatively small, and a higher control pressure can be used, the response and the stability of the capacity control is improved.
