Abstract
A wobble plate compressor in which the output of the compressor is modulated in response to refrigeration requirements by varying the compressor piston displacement to match the cooling requirement. An expansible chamber power unit including a sleeve surrounds the drive shaft in sealing relation therewith for axial movement with said sleeve including a wobble plate connected thereto for pivotal movement relative to the shaft. The wobble plate angle is varied during the axial movement of the sleeve by means of a drive lug on the drive shaft having a cam track therein connected in rotary driving relation to cam follower means on the wobble plate. The cam track opposite ends define respectively, maximum and minimum stroke lengths for each of the pistons whereby under controlled pressure conditions the force system results in the pistons tending to go to their full stroke positions.
