Abstract

PURPOSE: To eliminate parts such as a solenoid, etc., by driving a valve expanding or conracting a heating wire due to Joule heat produced on the heating wire.
CONSTITUTION: A diaphragm 3 positions a valve at the opening condition for unoperative time. For operative time, the flow in the fluid circuit is didected with a suitable detector, the voltage is applied to the heating wire 12 from the terminal 15, 16 obtaining the control voltage which is in proportion to the flow. The heating wire 12 expands, if the flow is increased, an actuator 9 moves the diaphragm 3 toward the shutting direction. If the flow is decreased, it is contracted, the actuator 9 is pulled against the spring 11 force, the diaphragm 3 moves toward the opening direction to open the valve by its elasticity force, the fluid flow is maintained constantly.
