ABSTRACT:
The invention related to a hydrostatic drive comprising a hydraulic pump (3) which is driven by a drive machine (2) and pumps into at least one first working line (4), and a pressure line (18) in which a feed quantity dependent on the speed of the drive machine (2) flows. When a differential pressure value in the pressure line (18) is exceeded, the pressure means can be extracted from the first working line (4).
