  • Patent number: 4872814
    Abstract: A passive destroker mechanism operated by centrifugal force is added to a variable stroke axial piston wobble plate refrigerant compressor. The destroker operates at a predetermined compressor speed to communicate the discharge side of the compressor with its sealed crankcase to thereby provide a controlled discharge gas bleed thereto to destroke the compressor to a desired displacement. Then after the speed is reduced below such trigger speed, the destroker mechanism operates to return the compressor to its normal stroke control condition.
