<p>PROBLEM TO BE SOLVED: To make do with a simple hydraulic circuit using no pressure compensating valve, enable to use a pressure detector of low accuracy and low price, always hold continuity of control by simple control so as not to apply a shock to an operator or mechanical components, do not limit the control system of a hydraulic pump, and dissolve load dependency of the flow of a hydraulic actuator at compound operation. SOLUTION: In a hydraulic circuit driving a plurality of hydraulic actuators 2, 3 provided in response to a hydraulic pump 1 and a plurality of operating elements 6, 7, correcting factors correcting the operating quantities of the operating elements 6, 7 in response to the operating valves are computed for respective operating elements based on the ratio detected pressure difference across the operating valves 4, 5 to the minimum pressure difference selected in the detected pressure difference across a plurality of operating valves. The operating quantities of the corresponding operating elements 6, 7 are corrected by the computed correcting factors.</p> |
