Abstract

In a hydraulic system, several consumers (4) are supplied by a common pump. In so doing, the consumers (4) are controlled by control valves (6). When the required oil flows exceed the quantity which can maximally be delivered, a control becomes operative which allows to adapt the reference value signals by which the valves (6) are controlled, to the actually measured pump flow, preferably to the weighting of the actually measured pump flow with the maximally predetermined pump flow.
