Abstract (en)
[origin: WO2008037306A1] A hydrostatic drive unit is disclosed for supplying pressure medium to a hydraulic consumer having two pressure spaces. According to the invention, the hydrostatic drive unit has an adjusting motor and two hydrostatic units which can be driven via the adjusting motor. Pressure medium is conveyed directly from one of the pressure spaces into the other pressure space via one of the hydrostatic units. The further hydrostatic unit conveys pressure medium from a tank into the lastmentioned pressure space or, depending on the drive direction, from the latter into the tank.
