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.
Claims8
A hydraulic system for feeding hydraulic fluid to a plurality of loads (4) from a common pump (1) at a rate not exceeding a predetermined capacity of said pump, comprising
- individual control valve means (6) associated with each of said plurality of loads for controlling the flow to each of said loads, and
- pressure balance means for directly measuring the actually delivered flow rate of said pump, and upon exceeding a predetermined limit value, controlling said loads by adjusting each of said control valve means in response to the actually delivered flow rate.
