摘要:
The arrangement (12') has a hydraulic pump (21) connected with a first hydraulic consumer (30), second hydraulic consumer and third hydraulic consumer (34) via first, second and third supply conduits (24-28). The first and second conduits are connected with the pump via a common load pressure steered priority valve (70). The third conduit is connected with the pump via an additional priority valve. A first load pressure spacer (62) is guided to the pump and connected with a second load pressure spacer (66) and a third load pressure spacer (42') of the third consumer. The common load pressure steered priority valve is designed as a 3/2-path proportional valve, 2/2- path proportional valve, and the hydraulic pump is designed as a load pressure-dependent variable flow pump and fixed displacement pump.
