Abstract
A controlled, variable displacement wobble plate compressor is provided with means for controlling the capacity by sliding the wobble plate to and fro along the drive shaft axis to vary the effective pumping capacity. The position of the wobble plate along the drive shaft axis is a function of the pressure maintained inside the crankcase, said position being a result of the various forces acting on the pistons, including the underside of the pistons where crankcase pressure is applied.
