量が減少する。 In the figure, 13 is a heat exchanger and 14 is a burner. Thus, when the lower end of the guide hole 8 of the movable member 9 communicates with the illustrated position of the bench lily 5, the pressure difference between the pressure in the other chamber 7 and the pressure in one chamber 3 according to the position is The diaphragm 1 and the regulating valve 2 interlocked with the diaphragm 1 are located at the positions shown in the figure, and an amount of water corresponding to the degree of opening of the regulating valve 2 flows out from the water outlet 6 via the valve 2 and is heated by the heat exchanger 13. When the operating shaft 12 is moved, for example, to the position indicated by the broken line so that the lower end of the guide hole 8 communicates with the lower end of the guide hole 8, the differential pressure applied to the diaphragm 1 increases, causing the diaphragm 1 to move upward and control the control valve 2.
The degree of opening of the valve decreases, and the amount of water flowing out from the water outlet 6 decreases.

In this embodiment, a bench lily 5 is formed in a passage 10 between one chamber 3 partitioned by a diaphragm 1 and a water outlet 6, and a movable member 9 movable in the axial direction of the bench lily 5 by a cam 15 is provided. One end of the guide hole 8 provided in the member 9 was communicated with the bench lily 5, and the other end was communicated through the hole 16 with the other end of a passage 17 whose one end opened into the other chamber 7, and the cam 15 was rotated. At this time, one end of the guide hole 8 communicates with positions of the bench lily 5 having different pressures.
