Abstract
PURPOSE: To obtain hot water having a constant temperature irrespective of the change in the amount of feed water, by coupling together a force producing unit and a control spring of a fuel pressure controller through the medium of a lever mechanism.
CONSTITUTION: Water coming in from a water piping 1 passes through a difference-in-pressure producing unit 4 having a throttle part 2, and is heated by a heat exchanger 7. A force producing unit 13 is composed of a main diaphragm 13 and two diaphragms 15 and 16, and a stem 19 is hooked in a lever 21 at near a upper end 19a of the stem 19. The displacement of the stem 19 can be enlarged at a free end side of the lever by virtue of a position relation of the lever fulcrum 22. A valve poppet 23 of a fuel pressure control valve 11 is fixedly arranged at a fuel diaphragm 25, and a slidable part 28 being other end of a control spring 26 is supported at the free end of the aforesaid lever 21. Suitable selection of the aforesaid lever ratio may result in the change in the load of the control spring 26, and in proportioning the change in a gas volume to the change in a water amount.
