ある。There is a variable operating force generating means 19 on the water flow path 2 side, the variable operating force generating means 19 has an iron core 20 and a waterproof and insulated coil 21 around the iron core 20, and the coil 21 is connected to the control circuit 18. ing. 22 and 23 are plugs, and the plug 23 has a force generating means (spring) 24.
is attached to urge the automatic pressure regulating valve 3 upward. By adjusting the current to the coil 21, the magnitude of the force acting on the iron core changes, and the hot water side valve body 4 and the water side valve body 6
, the automatic pressure regulating valve 3 can be moved in balance with the forces acting on each of the springs 24. In order to eliminate the amount of leakage from the water side, the gap between the partition wall body 9 and the bearing 25 is made small. 26 and 27 are orifices, respectively.

安定している。As a result, the water side is closed and the hot water side is opened, and the outlet pressures PH2 and PO2 of the hot water side valve body 4 and the water side valve body 6 change, respectively, and the automatic pressure regulating valve 3 is balanced. As a result, the temperature of the mixed water increases. Further, when the current in the coil 21 is reduced, the downward force on the iron core 20 is reduced, and the force of the spring 24 moves the valve shaft 8 upward, opening the water side and closing the hot water side. As a result, the mixed water temperature becomes lower. By changing the current flowing through the coil 21 in this way, the balance point of the automatic pressure regulating valve 3 can be moved. The mixed water temperature is detected by a thermistor 15 and calculated by a control circuit 18 to control the current to the coil 21. When the water pressure fluctuates, the automatic pressure regulating valve 3 operates as in the past, and the hot water side valve body 4, the water side valve body 6 and the partition wall body 9 are operated.
If the pressure receiving area is made almost equal to the secondary pressure PH2
and PO2 are maintained at the balance point by the variable operating force generating means 19, the change in the mixing ratio of hot water and water is small, and the hot water temperature is stable.

The electromagnetic force is removed from the valve stem 8 by the spring 24.
moves upward, and as shown in FIG.
5 and moves to the recessed portion, and there is no need to worry about sticking at the outer periphery of the partition wall body 9. In addition to using a spring, it is also possible to use electromagnetic force or the gravity of a valve body as a means for generating deflection.

The center position of the valve stem 8 is maintained when it is removed from the center. At this time, the tip of the guide 9 comes into contact with the bearing 25, but sticking can be prevented by reducing the contact area.

A minute alternating current signal is superimposed on the drive signal. This dither signal causes the automatic pressure regulating valve 3 to vibrate slightly. This minute vibration is set to a magnitude and frequency that does not cause a change in the mixed water temperature. This dither signal prevents scale and dirt from accumulating during operation.
