Abstract
A hydrostatic drive system has a pump () and at least one consumer () controlled by a control valve () that can be actuated by control signals. A precharge device () that generates a precharge pressure is located in a reservoir line () that leads from the control valve () to a reservoir (). The precharge device can be pressurized as a function of the control signals of the control valve (). To make possible a recharge during the deceleration of a consumer, the precharge device () can be pressurized in the direction of an elevation of the precharge pressure when there is a decreasing control signal of the control valve ().
