Abstract

PURPOSE:To stabilize the temperature of water by controlling the amount of fuel basing on the flow amount and the temperature of supplied water. CONSTITUTION:Necessary amount of fuel is calculated by detecting the flow amount and the temperature of supplied water to a heat exchanger and controlling signal is sent to a fuel controlling valve 10 and a pilot valve 16. The controlling valve 10 has a magnetic pump 12 in a casing 11. When a signal from the controlling circuit is input to a coil 13, moving liquid is pressed from the first chamber 14 or the second chember 15 to the other chamber through a pilot valve 16 controlling the opening degree of the valve body 20 via a movable body 18 and a shaft 19 thereby controlling the amount of fuel. The pilot valve 16, provided in a pipe path 17 that links the first chamber 14 and the second chamber 15, inputs a signal from the controlling circuit to the coil 26 moving a plunger 27 and driving a valve 29 mounted on a diaphragm 28, adjusting the opening degree of the opening 30 thus controlling resistance of pipe path 17.
