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