Filed: 1991-01-25
Abstract: PURPOSE:To improve fine operability by making the operator perform the intended action even when a hydraulic actuator with high inertia is driven. CONSTITUTION:Detectors 11a-12b for detecting the manipulated variable of manipulating devices 11, 12 and a setting means for setting the relation between the manipulated variable of manipulating devices 11, 12 and the discharge pressure of a pump 2 and the load pressure of hydraulic actuators 4, 5 in advance are installed. The relation is set so that as the manipulated variable increases, the differential pressure increases gradually, and it becomes constant after the manipulated variable reaches the specified value. An arithmetic unit 22 is installed to perform arithmetic operation for determining differential, pressure corresponding to the signal value from the relation set by the setting means by taking signals from the detectors 11a-12b. In addition a control unit 24 is installed to output control signals in accordance with the arithmetic operation result of the arithmetic unit 22.
