Latest Patents

Weiming Ma holds a patent for a "Variable displacement compressor passive destroker." This invention introduces a passive destroker mechanism that operates using centrifugal force. The mechanism is integrated into a variable stroke axial piston wobble plate refrigerant compressor. It functions at a predetermined compressor speed to connect the discharge side of the compressor with its sealed crankcase. This design allows for a controlled discharge gas bleed, effectively destroking the compressor to a desired displacement. Once the speed drops below the trigger speed, the destroker mechanism reverts the compressor to its normal stroke control condition. This innovation is crucial for optimizing compressor performance and energy efficiency.
