Abstract

See full text

Variable displacement hydraulic unit comprising a displacement unit for setting/adjusting the position of an adjustment element in order to adjust the displacement volume of the hydraulic unit by means of an electronically driveable actuator. The actuator is electronically connected to an electronic control unit (ECU) and has a first electric conductive coil to position the adjustment element by the help of electro-magnetic forces. An electric energy harvesting device is located adjacent to the first coil of the actuator such that electric energy from power fluctuations in the first coil can be harvested inductively. The inductively harvested electric energy can be transmitted to an electric energy storage device.
