Abstract
A pressure supply device for prioritised volume flow splitting, in particular in mobile working machines, includes at least one adjusting pump () controllable by an LS signal as main pump, a constant-displacement pump () as an auxiliary pump, and two pressure balances. A system is supplied primarily, in particular in the form of steering hydraulics (PL), which outputs an LS signal. A system is supplied secondarily, which outputs a further LS signal, in particular in the form of working hydraulics (PA). A further system is supplied hydraulically, in particular in the form of brake hydraulics (PB). One pressure balance (DW) is used to supply the system (PL) to be supplied primarily and/or the further hydraulic system (PB), the other pressure balance (DW) is used to supply the system (PL) to be supplied primarily and/or the system (PA) to be supplied secondarily, The respective pressure balance (DW, DW) can be activated by an LS signal in such a way that the constant-displacement pump () is also used to supply the system (PA) to be supplied secondarily.
