ABSTRACT:
An axial piston, variable displacement, wobble plate gas or vapor compressor having improved wobble plate control for rapid response to a compressor inoperative mode. Either a mechanical or spring means serves to maintain the reference position during inoperation of the compressor. This control of the wobble plate position provides for rapid response during either operation or inoperation of the compressor, and also provides a stabilizing means which inhibits undesired wobble plate movement at low crankcase pressures.
