Abstract
A fluid flow control valve comprises a fluid heating device for supplying a heat energy to a fluid, a valve device for controlling a flow rate of the fluid, an electromagnetic coil for generating a magnetic field at the fluid heating device and the valve device so that the fluid heating device is heated to supply the heat energy to the fluid and the valve device is operated to control the flow rate of the fluid, and a power source for applying a voltage to the electromagnetic coil to generate the magnetic field, the power source supplying a current whose value fluctuates to the electromagnetic coil when the fluid heating device supplies the heat energy to the fluid.
