Abstract

A hydrostatic drive system has a consumer (7), in particular a hydraulic motor, located in the open circuit. Associated with the consumer (7) is at least one pressure limiting device (11a; 11b) that can be actuated in the braking phase for the generation of a braking pressure that is present on the discharge side of the consumer (7) from a minimum response pressure in the direction of an increase of the response pressure. A feeder device (12a; 12b) provides a feed of pressure fluid into the admission side of the consumer (7). The pressure limiting device (11a; 11b) and the feeder device (12a; 12b) are integrated into a valve unit (10a; 10b).
