PROBLEM TO BE SOLVED: To provide a hydrostatic adjusting device which can be switched between a load-rigid response and a load-flexible response of a drive device.SOLUTION: The swept volume of a hydraulic machine 1 is adjusted by way of a servo adjusting unit 9. The servo adjusting unit has a control unit 10 having a control cylinder 17 having an inlet for pressurized working fluid, a servo connector for a connecting line to the servo adjusting unit, and an outlet to a working fluid collecting region. A control piston 18 is arranged in the control cylinder. The control piston can be displaced by means of a control piston actuator 21, and has a control edge. In interaction with the control edge configured in the control cylinder, the inlet or the outlet can be alternately connected hydraulically to the connecting line, whereby the pressure which prevails in the connecting line can be returned hydraulically via a control line 32 to at least one of end sides 19, 20 of the control piston. The control line can be opened and closed with a load response valve 30. |
