Abstract

PURPOSE:To simplify an apparatus and to lessen dead zone of a pressure control valve by obtaining a deviation between the position of a controlled system and a target position and controlling a flow control valve according to a signal subjected to pulse-duration modulation corresponding to the deviation. CONSTITUTION:A pressure control valve 14 controlled by pilot pressure of a solenoid valve 13 is connected to an actuator 15, and output of from a position sensor 17 of the actuator 15 is input to an electronic control device 18. In the electronic control device 18, a deviation between a signal from the position sensor 17 and a signal from target value generating means 19 is obtained, and corresponding to the deviation, a pulse signal is subjected to pulse-duration modulation to drive a solenoid valve 13 according to the signal. Thus, dead zone of the pressure control valve 14 can be eliminated or lessened, and the need of judder generating means can be eliminated so as to simplify the device.
