シングである。Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a hot and cold water mixing apparatus, and the same parts as those in FIG. 5 are denoted by the same reference numerals. 19 is a biasing means, 20
Is a variable bias means for applying a variable bias force in opposition to the force of the biasing means 19. The variable bias means 20 is
A plunger 21 made of a magnetic material and a waterproof and insulated coil 22 around the plunger 21 are provided.
22 is connected to a variable power supply 23. The strength of the biasing means 19 can be adjusted by rotating the adjusting operation means 24 having the screw 24a. The urging means 19 is composed of, for example, a spring.

している。Next, the operation of the present invention will be described. Coil from external power supply 23
When a current is applied to 22, the plunger 21 made of a magnetic material applies a biasing force to the valve shaft 8 according to Fleming's law. When the bias force and the urging force of the urging means 19 are balanced, the automatic pressure regulating valve 3 is balanced. Therefore, coil 22
It is possible to move the balance point of the automatic pressure regulating valve 3 by changing the current flowing to the. For example, when the current is small, the force of the urging means 19 is stronger, so that the water-side valve body 6 opens more than the hot-water-side valve body 4, and the tapping temperature decreases. When the current is increased, the plunger 21 is pushed out against the force of the urging means 19, so that the hot-water-side valve body 4 opens, and as a result, the hot-water tapping temperature increases. When the water pressure fluctuates, the automatic pressure regulating valve 3 operates as in the conventional case, and if the pressure receiving areas of the hot water side valve body 4, the water side valve body 6 and the piston 9 are made equal, the secondary pressures PH2 and PC2 are energized. The state at the balance point by the means 19 and the variable bias means 20 is maintained, the change in the mixing ratio of hot water and water is small, and the hot water temperature is stable.

温の変動は小さい。When the power supply is stopped due to a power failure or the like, or when control becomes impossible due to some abnormality of the device, the control by the variable bias means 23 cannot be performed. In this case, the hot water temperature can be adjusted by manually rotating the adjusting operation means 24. Since both ends of the urging means 19 are fixed to the automatic pressure regulating valve 3 and the adjusting operation means 24, positive and negative forces can be generated by the rotation of the adjusting operation means 24. Even during manual adjustment, when the water pressure fluctuates, the automatic pressure regulating valve 3 operates, so that the fluctuation of the hot water temperature is small.
