Abstract: The invention relates to a hydrostatic drive, which is used in particular to start an internal combustion engine. The drive comprises a hydraulic machine, which can be adjusted in the swept volume thereof from a maximum positive swept volume to a maximum negative swept volume via a zero swept volume by means of a hydraulic adjusting device and which can be operated as a pump with positive swept volume and as a motor with negative swept volume, a high-pressure accumulator, from which the hydraulic machine can be supplied with pressure medium for operation as a motor via a pressure line, which extends between a pressure connection of the hydraulic machine and the high-pressure accumulator, an accumulator-closing valve having a first position and a second position, which is arranged in the pressure line and by means of which a fluidic connection from the high-pressure accumulator to the hydraulic machine is open in the first position and closed in the second position, and an electronic control unit, in accordance with the signals of which the accumulator-closing valve can be actuated. The problem addressed by the invention is that of designing the hydrostatic drive in such a way that the components of the hydraulic machine are not subjected to high wear and a quick return from the range of negative swept volumes occurs. This problem is solved in that, in the event of an adjustment of the hydraulic machine from a negative swept volume to a positive swept volume, the electronic control device gives a signal for switching over the accumulator-closing valve from the first position to the second position and in that the accumulator-closing valve does not switch over to the second position until there is a zero swept volume or a positive swept volume of the hydraulic machine.

Abstract: What is disclosed is a hydrostatic drive having a diesel engine and having a hydrostatic adjustable machine (10) which in normal operation as a pump can supply multiple consumers. The machine has a pressure/flow regulator (34) to which is communicated, according to the load-sensing principle, the highest load pressure of the consumers, in particular when the machine is operated as a pump. In order to realize a start/stop function of the diesel engine, it is possible for a previously charged high-pressure reservoir (16) to supply the hydrostatic machine, which then acts as a starter motor for the diesel engine. In order to switch from pump to starter motor, the hydro-machine is adjusted over zero. In order for this to take place quickly and reliably, it is possible for the pressure/flow regulator to be deactivated by means of a switching valve (48) and for the adjustment device to be supplied with an adjustment pressure medium via the switching valve, which medium is taken from the high-pressure reservoir or from an auxiliary reservoir.
