Abstract
PURPOSE: To obtain hot water having a constant temperature irrespective of the flactuation in the amount of feed water, by coupling together a lever mechanism, which compares forces of a high and low diaphragm of a difference-in-pressure producing unit producing the difference in pressure.
CONSTITUTION: Water comes in from a water piping 1 and passes through a difference-in-pressure producing unit 5. Water, which becomes hot water after being heated by a heat exchanger 6, comes out from a faucet 7. Gas fed from a gas piping 17 passes through a switch valve 18, and gas controlled by a fuel feed controller 19 is burned at a burner 23. The difference-in-pressure producing unit 5 is connected to a throttle part 3 to provide a low pressure chamber 8, and is positioned in in parallel to a high pressure chamber 2. A force working on a No.1 diaphragm 9 and No.2 diaphragm 10 is transferred to a lever 4, and a moment centering around a fulcrum 13 acts. The end of a valve poppet 20 of a diaphragm 22 of the fuel pressure controller 19 is in contact with one end of the lever 14, and thus, a gas volume and a water amount can be regulated to be mutually proportioned by suitably selecting a lever ratio.
