も大きくなって好ましくないという課題を有していた。However, in the above-mentioned configuration, although the reliability and durability are improved by the rotation of the blades 10, the rotation speed changes depending on the amount of tapping water, and it is difficult to rotate especially at the time of small tapping, and the pressure loss becomes large. Had the problem that it was not desirable.

21は可撓部23を介して交流電源24に接続されている。FIG. 1 is a sectional view showing a schematic configuration of an automatic pressure regulating valve showing an embodiment of the present invention. Here, the same components as those of the conventional automatic pressure regulating valve are indicated by the same numbers. This automatic pressure regulating valve 3 has almost the same structure as the conventional one, but is different from the conventional automatic pressure regulating valve in that no blade for rotating the valve body is provided, and instead, a slight vibration is generated on the connecting shaft 8. That is, a vibrating means 19 for imparting is provided. The vibrating means 19 includes a bobbin 20 integrally formed on an end of the connecting shaft 8, a coil 21 wound around the bobbin 20 and insulated, and this coil.
A permanent magnet 22 provided so as to surround 21
21 is connected to an AC power supply 24 via a flexible portion 23.

よる吸引・反発を利用する構成を用いてもよい。In the above configuration, the AC power supply 24 is always applied, and an AC current is flowing through the coil 21. The current traverses the magnetic field generated by the permanent magnet 22, so that a slight vibration is generated in the connecting shaft 8 according to Fleming's law. By setting the frequency as fast as the AC power source and setting the amplitude small, this vibration does not affect the pressure regulating function at all, but rather moves smoothly, thereby improving the pressure regulating performance. At this time, what is important is that, as shown in FIG. 2, the amplitude x of the vibration does not change significantly depending on the piston position. For this reason, the embodiment uses the Fleming's law. ing. In addition to this, a structure such as a linear motor may be used, or a structure that uses attraction / repulsion due to electromagnetic force although the amplitude slightly changes depending on the piston position may be used.
