Abstract
Disclosed is a hydraulic system for utility vehicles, in particular agricultural tractors, for supplying primary and/or auxiliary pressure medium consumers with pressure medium, comprising a pump, sucking from a pressure medium tank, the pump being controlled as a function of the load pressure of the pressure medium consumers and supplying a pump pressure exceeding the load pressure by a predetermined control pressure differential. The hydraulic system produces a first control pressure differential for operating a primary pressure medium consumer and a second higher control pressure differential for operating an auxiliary pressure medium consumer. The hydraulic system obtains rapid response of an actuated primary pressure medium consumer and prevents, under certain conditions due to thermal expansion, pressure medium from flowing to the pressure and flow controller of the pump and possibly causing unwanted restriction of the pump.
