ABSTRACT:
A variable capacity wobble plate compressor including a fluid actuator for shifting the centering ball, on which the cam mechanism is supported, to effect a change in the length of stroke by varying the angle of inclination of the wobble plate with respect to the drive shaft axis. A control system automatically responds to suction pressure (or some other predetermined variable to be controlled) to operate the fluid actuator.
