付勢する。1 is a hot water flow path, 2 is a water flow path, and an automatic pressure regulating valve 3 is provided in relation to each flow path. The automatic pressure regulating valve 3 includes a hot water side valve body 4. which reduces the primary pressure PH1 of the hot water side flow path 1. Hot water side valve seat 5
and a water side valve body 6 that reduces the primary pressure PC1 of the water side flow path 2.
.. Consisting of a water side valve seat 7, a common shaft 8 connecting the hot water side valve body 4 and the water side valve body 6, and a piston 9 that operates based on the pressure difference between the secondary pressures PH2 and PO2 after depressurization of the hot water and water. Even if the pressure of hot water or water suddenly changes, the automatic pressure regulating valve 3 moves with that pressure, and acts so that the secondary pressures PH2 and PO2 of hot water and water are always kept equal. The mixing ratio of hot water and water is varied by moving a temperature control valve 12 energized by a motor 11 from side to side to change the mixing temperature. Reference numeral 13 denotes a mixing section for hot water and water. After mixing, the hot water is discharged via a flow rate regulating on-off valve 14. The temperature of the hot water is detected by a thermistor 15, the flow rate is detected by a flow rate sensor 16, and the value of the setting device 17 is detected. (The controller 18 energizes the motor 11 and the flow rate adjustment on-off valve 14.
発明が解決しようとする課題

12とが独立しているために、形が大きくなるとともに
圧損も大きくなり、狭い浴室に設置する場合、またマツ
サージシャワーなど大流量を必要とする場合に課題とな
る。Problems to be Solved by the Invention However, in the above configuration, since the pressure regulating valve 3 and the temperature regulating valve 12 are independent, the size becomes larger and the pressure loss also becomes larger. This becomes an issue when a large flow rate is required, such as in a pine surge shower.
本発明はかかる従来の課題を解消するもので、調圧弁と
温調弁とを1つにし、しかも各々の機能が独立して果す
ことができることを目的とする。The present invention solves such conventional problems, and aims to integrate a pressure regulating valve and a temperature regulating valve into one, and to enable each function to be performed independently.

備えたものである。Means for Solving the Problems In order to solve the above problems, the automatic pressure and temperature control valve of the present invention has the following features:
It is equipped with variable bias means that applies variable bias force to the same axis.

である。Effects of the Invention With the above-described configuration, the pressure regulation operation is performed without any trouble because there is no change in the bias voltage even if the same axis moves due to fluctuations in water pressure during pressure regulation, and the pressure regulation operation is performed without any trouble by changing the bias force during temperature regulation. Since the pressure balance point can be moved, the mixing ratio of hot water and water can be changed.

は可撓部23を介して可変電源24に接続されている。A pressure regulating section and a temperature regulating section are shown, and the same components as in FIG. 3 are indicated by the same numbers. The difference from FIG. 3 is that a bias means 19 is provided on the same shaft 8;
The coil 21 has a bobbin 20 coupled to an end thereof, a coil 21 wound and insulated on the bobbin 2o, and a permanent magnet 22 provided to sandwich the coil 21.

。In the above configuration, assuming that the voltage of the variable power supply 24 is zero, when the water pressure fluctuates, the flexible portion 23 allows the automatic pressure regulating valve 3 to operate freely as in the past, for example, the hot water side valve 4. If the pressure receiving areas of the water side valve 6 and the piston 9 are made equal, the secondary pressures PH2 and PO2 will always remain equal. However, when a current is passed through the coil 21 from the external power source 24, the current crosses the magnetic field generated by the permanent magnet 22, so that a pie spacing is applied to the same axis 8 according to Fleming's law. For this reason, the automatic pressure regulation point is shifted by the amount of the pie spacing, and, for example, the secondary pressures PH2 and PO2 of hot water and water are always regulated at a point where 2=1, and as a result, the temperature of the hot water becomes high. What is important at this time is that in order to accurately adjust the pressure when the water pressure fluctuates, as shown in the characteristic diagram in Figure 2,
The piascus does not change depending on the piston position, but has a characteristic that can be changed only by the current I. In other words, it is necessary that the piascus act as a bottom thorn force.
その手段としては、この例に示すようなフレミングの法
則を用いたものや、リニヤモータのような各種構成が考
えられる。Possible means for this purpose include one using Fleming's law as shown in this example, and various configurations such as a linear motor.

を同じ弁で行えるため、下記の特長を有する。As described above, the automatic pressure and temperature control valve of the present invention has a variable bias means that applies a variable bias force to the same shaft, and has an automatic pressure control function when water pressure fluctuates and changes the bias force to automatically adjust the pressure. Since the same valve can perform the temperature control function of changing the mixing ratio of hot water and cold water by moving the pressure control balance point, it has the following features.
