実施例 以下、本発明の一実施例を図面を用いて説明する。な
お、第１図は湯水混合装置の断面図で第３図と同一部品
については同一番号を付している。Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of the hot and cold water mixing apparatus, and the same parts as those in FIG. 3 are denoted by the same reference numerals.
19は付勢手段で、20は前記付勢手段19の力と対向して
可変バイアス力を付与する可変バイアス手段である。可
変バイアス手段20は、磁性体からなるプランジャ21と、
前記プランジャ21の周りに防水および絶縁されたコイル
22を有し、前記コイル22は可変電源23に接続されてい
る。Reference numeral 19 denotes an urging unit, and 20 denotes a variable bias unit that applies a variable bias force in opposition to the force of the urging unit 19. The variable bias means 20 includes a plunger 21 made of a magnetic material,
Waterproof and insulated coil around the plunger 21
The coil 22 is connected to a variable power supply 23.
次に本発明の動作を説明する。 Next, the operation of the present invention will be described.
外部電源23からコイル22に電流を流すと、磁性体から
なるプランジャ21はフレミングの法則により弁軸８にバ
イアス力を付与する。このバイアス力と付勢手段19の付
勢力がつりあったところで自動調圧弁はバランスする。
したがって、コイル22に流す電流を変化することにより
自動調圧弁３のバランス点を移動することができる。When a current flows from the external power supply 23 to the coil 22, the plunger 21 made of a magnetic material applies a bias force to the valve shaft 8 according to Fleming's law. When the biasing force and the urging force of the urging means 19 are balanced, the automatic pressure regulating valve balances.
Therefore, the balance point of the automatic pressure regulating valve 3 can be moved by changing the current flowing through the coil 22.
例えば、電流の小さい場合は付勢手段19の力の方が強
いため湯側弁体４より水側弁体６の方が大きく開き、出
湯温度が低くなる。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.
電流を大きくすると付勢手段19の力に対向してプラン
ジャ21を押し出すことにより湯側弁体４が開きだし結果
的に出湯温度が高くなる。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.
水圧変動時には従来と同様に自動調圧弁３が動作し、
湯側弁体４、水側弁体６とピストン９との受圧面積を等
しくしておけばその２次圧PH2とPC2とは付勢手段19と可
変バイアス手段20によるバランス点での状態を保つ。When the water pressure fluctuates, the automatic pressure regulating valve 3 operates as before,
If the pressure receiving areas of the hot water side valve element 4, the water side valve element 6 and the piston 9 are made equal, the secondary pressure PH2 and PC2 are maintained at the balance point by the urging means 19 and the variable bias means 20. .

示すようなフレミングの法則を用いたものや、リニアモ
ータのような各種構成が考えられる。In order for pressure regulation to be performed accurately when the water pressure fluctuates,
As shown in the characteristics of the figure, the bias force does not change depending on the piston position, but can be changed only by the current I. That is, the bias force needs to act as a bottom-up force. As means therefor, means using Fleming's law as shown in this example and various configurations such as a linear motor can be considered.

And a valve shaft that opposes the force due to the outlet pressure of the water-side valve element to each other, an urging unit that urges the valve shaft, and a variable bias unit that applies a variable bias force that opposes the force of the urging unit. In addition, since the same valve can be used to perform the automatic pressure adjustment function when the water pressure fluctuates and the automatic pressure adjustment balance point by changing the bias force to change the mixing ratio of hot water and water, the following effects can be obtained.
（１） 温度調節がバイアス力を変えてできるため高速
に行え、過渡偏差が少ない。(1) The temperature can be adjusted by changing the bias force, so that the temperature can be adjusted at high speed and the transient deviation is small.
（２） 付勢手段の力と可変バイアス手段の力が対向し
ているためバイアス手段の力は一方向のみで良い。(2) Since the force of the urging means and the force of the variable bias means are opposed to each other, the force of the bias means only needs to be in one direction.
（３） 水路の圧損が小さくなるので、大流量を必要と
する場合に適しており、システム自由が向上する。(3) Since the pressure loss in the water channel is small, it is suitable when a large flow rate is required, and the system freedom is improved.
（４） 形を小さく構成できるため浴室で使用する場
合、突出部も小さくできるので完全になる。(4) When used in a bathroom because the shape can be made small, the projections can be made small so that it is complete.
（５） 可変バイアス手段の駆動力を小さくすると出湯
