Hydrostatic Drive

A hydrostatic drive, comprising:

• a hydraulic machine with an adjustable swept volume;
• a hydraulic adjustment device configured to adjust the swept volume of the hydraulic machine from a maximum positive swept volume via a swept volume of zero to a maximum negative swept volume, the hydraulic machine is operable with positive swept volume as a pump and with negative swept volume as a motor;
• at least one high-pressure accumulator from which the hydraulic machine is configured to be supplied with pressure medium via a pressure line for operation as a motor, the pressure line running between a pressure port of the hydraulic machine and the high-pressure accumulator;
• an accumulator shut-off valve arranged in the pressure line and having a first position and a second position, a fluidic connection from the high-pressure accumulator to the hydraulic machine is open in the first position of the accumulator shut-off valve and is shut off in the second position of the accumulator shut-off valve;
• and
• an electronic control unit, the accumulator shut-off valve actuable as a function of signals of the electronic control unit,
• wherein, in the event of an adjustment of the hydraulic machine from a negative swept volume to a positive swept volume, the electronic control unit transmits a signal for switching the accumulator shut-off valve from the first position into the second position at such a time that the accumulator shut-off valve switches into the second position only in the presence of a swept volume of zero or a positive swept volume of the hydraulic machine.
