Abstract (en)

[origin: EP2256082A2] The system has a pump (1) i.e. fixed displacement pump, for supplying a consumer with a working hydraulic system (2) and a hydraulic steering unit (3). A hydraulic braking device (20) is controlled by brake pressure. A priority valve (5) is arranged for preferred supply of the steering unit in a conveyor pipe (4) of the pump. A control pressure pipe (25) is provided with the conveyor pipe of the pump located upstream of the priority valve of the steering unit for generation of the brake pressure. The control pressure pipe is guided to a brake valve (21) of the braking device.
