In a control for a hydrostatic drive system with a primary energy source and with an adjustable pump and at least one adjustable consumer of hydrostatic energy and with a pump adjusting piston connected with the adjusting element of the pump and capable of sliding in a pump adjustment cylinder, where the load on the pump adjustment cylinder is regulated by means of a servo control valve, also with a constant pump connected to the drive shaft of the pump, the delivery line of which leads to a restrictor and to which a signal-pressure line is connected in front of the restrictor, where the pressure-signal present in it regulates a relief valve jet, which in turn is located in a control-signal line, the improvement characterized in that an additional restrictor is located in the control-signal line and means are provided for switching the pressure gradient in it to the servo control valve.
