Abstract

PURPOSE:To compensate the reduction of response for a hydraulic control system, by increasing the time of application for the indicated signal of a time as the temperature lowers for the hydraulic oil consumed by the hydraulic control system. CONSTITUTION:The differenece is obtained between the working temperature of a hydraulic pump device 3 and the temperature of the oil stored in a memory E. A microcomputer 5 transmits an indication signal of the time of application having the time width of the component which is adversely proportional to the temperature of the hydraulic oil to an electric wire 5k, to minimize the deviation between the indication target value to the load and the set value of the load. As a result, an solenoid valve 5F works in a single direction and the pressurized oil supplied from a device 3 actuates a hydraulic actuator in a jet period controller 2 in a single direction to ensure a proper fuel jet period of a fuel jet pump 4.
