Abstract

PURPOSE: To accurately control the flow rate control valve by provinding the variable resistor and the fluid pressure type driving device to the flow control valve and the magnetic valve to control the flow rate to the fluid pressure type driving device by comparing the output and the input from the variable resistor.
CONSTITUTION: The variable resistor VR2 and the fluid pressure type driving device 3 are provided to the flow rate control valve 1, and the electromagnetic valve 4 to control the flow rate to the fluid pressure type driving device 3 corresponding to the difference between the output from the variable resistor VR2 and the output from the variable resistor VR1 of the input part. By doing so, the voltage V1 of the variable resistor VR1 of the input part and the voltage V2 at the variable resistor VR2 of the flow rate control valve 1 are compared by the comparator, and the electromagnetic valve 4 is switched by the output from one of the comparator to control the valve system control member 2 by the fluid pressure type driving device 3 toward the direction that the potential difference becomes zero, so as that the flow rate control valve 1 can be controlled accurately.
