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).
