ABSTRACT:
A hydrostatic drive system (1) has a load-sensing pump (2) with an adjustable discharge volume and at least one consumer connected to the pump (2). The discharge volume of the pump (2) can be set by a discharge volume control device (6) that sets the delivery pressure of the pump available in a delivery line (4) of the pump (2) so that it is higher by a pilot control pressure difference than the load pressure of the consumer. The discharge volume control device (6) can be actuated by an electronic control device (7) functionally connected with a sensor device (9) for measuring the load pressure of the consumer and with a sensor device (8) for measuring the delivery pressure available in the delivery line (4). A circulation device (15) is associated with the delivery line (4) to control the connection of the delivery line (4) with a reservoir (3).
