Abstract (en)
[origin: EP0656447A1] A proposal is made for a control system for splitting up the delivery flow made available by at least one pump (20) in hydraulic systems between a plurality of loads according to the principle of load pressure independence when the loads (8, 9) are undersupplied, a compensator (26, 27) essentially comprising a piston (28, 29) and an actuating element being arranged downstream of each spool valve, which has a predetermined control cross-section, and each load (8, 9) arranged downstream of the compensator (26, 27) receiving a predeterminable portion of the delivery flow as a function of the degree of undersupply by virtue of the fact that the pistons (28, 29) of the compensators (26, 27) are subjected to different forces, which bring about different opening pressures. <IMAGE>
