A hydrostatic drive system has a pump ( 1 ) and at least one consumer ( 5 ) controlled by a control valve ( 4 ) that can be actuated by control signals. A precharge device ( 10 ) that generates a precharge pressure is located in a reservoir line ( 7 ) that leads from the control valve ( 4 ) to a reservoir ( 2 ). The precharge device can be pressurized as a function of the control signals of the control valve ( 4 ). To make possible a recharge during the deceleration of a consumer, the precharge device ( 10 ) can be pressurized in the direction of an elevation of the precharge pressure when there is a decreasing control signal of the control valve ( 4 ).
