Abstract
The invention relates to a hydrostatic drive comprising a hydraulic pump (1) and at least one hydraulic engine (3). Said hydraulic engine (3) is contacted to a closed circuit via a first working line (5) and a second working line (6). In order to limit the swept volume flowing in one of the two working lines (5) towards the hydraulic pump (1), a volume flow divider (60) is provided in the working line (5) and allows to remove a partial volume flow from the working line (5).
Claims9
Hydrostatic drive having a hydraulic pump and at least one hydraulic engine which is connected to said hydraulic pump via a first working line and a second working line,
- wherein
- for the purpose of limiting a delivery volume flowing in one of the working lines towards the hydraulic pump, a volume-flow-divider is provided in the said working line for the purpose of removing a partial volume flow from said working line, said volume-flow-divider having a control-pressure-regulating valve for the purpose of producing a control pressure which is dependent upon a volume flow in said working line.
