Abstract
A control valve is provided in a line between a variable displacement hydraulic pump and a hydraulic cylinder. The control valve controls flow rate of working fluid supplied to the hydraulic cylinder according to a manipulated variable of a lever. The control increases a discharge of the hydraulic pump in association with the increase in the manipulated variable and also controls to suppress the discharge as the discharge pressure of the hydraulic pump increases. A proper response corresponding to the operator's feeling can be realized in consideration of an actual pressure loaded on an actuator on the basis of a positive control system.
