Abstract (en)
[origin: WO9210684A1] Disclosed is a hydraulic system in which several consumers (5', 5''; 5''') are powered by a common pump (1). The pump (1) is controlled as a function of the difference between the pump pressure (Delta P) and the maximum load pressure. This pressure difference (Delta Pmax) is compared with a minimum pressure difference (Delta Pmin) and the signal resulting from this comparison process used in a control unit (21) to adjust the reference-value signals (S1, S2, S3) with which the individual valves (6'; 6''; 6''') are controlled.
