  • Variable stroke pump
    Patent number: 11686295
    Abstract: A variable stroke high pressure pump is disclosed. The pump uses a wobble plate design with dynamically variable tilt to provide continuous adjustment of pump stroke length and output. Dynamically variable tilt is accomplished using a linearly actuated tilt thruster rotationally coupled to the drive shaft to maintain a selected tilt of the wobble plate through the rotation of the wobble plate.
    Type: Grant

  • Piston with a heat exchanger
    Patent number: 9581154
    Abstract: A piston with an integrated heat exchanger comprises a seal, a piston hub and a piston rod. The piston hub is further provided with a coolant reservoir and an outlet nozzle at its lateral surface. The heat exchanger integrated into the piston hub and/or the piston hub include a coolant manifold, a coolant passage communicating thereto, and a plurality of channels connecting to the coolant manifold and extending radially to the annulus. Said heat exchanger provides enhanced efficiencies of heat-exchange and debris-flushing.
