周壁に接している。The first embodiment of the present invention will be fully explained below with reference to FIGS. 3 to 5. A donut-shaped bag portion 11 is provided on the inner peripheral wall of the tube 1 through which fluid flows. The axis of this toroidal shape coincides with the axis of the tube 1. The outer periphery of the donut shape is in contact with the inner peripheral wall of the tube 1.

周に環状金なして配置されている。This bag portion 11 has a shape that seals the magnetic fluid 12 inside. The material of the bag portion 11 is synthetic rubber, which is a flexible membrane. A plurality of U-shaped electromagnets 13 are provided on the outer periphery of the tube 1. Each electromagnet 13 has both poles facing toward the tube 1, and these electromagnets 13 as a whole are arranged around the outer periphery of the tube 1 in a ring shape.

At this time, the magnetic fluid 12 sealed inside the bag portion 11 does not have an integral shape, but is in a flat state as shown in FIG. Next, when operating the orifice, a current is passed through the electromagnet 13,
The magnetic fluid 13 inside the bag portion 11 is as shown in FIG.
It has a shape that rises along the magnetic flux 14. As a result, the donut-shaped bag portion 11 protrudes toward the center of the tube 1 over the entire circumference of the donut shape, and the orifice is in a constricted state.

It is also possible to simply attach a bag portion to a part of the inner wall of the tube, seal the magnetic fluid inside the bag portion, and apply a differential force using an electromagnet in the same manner as described above, thereby functioning as a variable orifice. Furthermore, the bag portion may be suspended over the central portion of the tube 1, and an electromagnet may be provided on the outer periphery of the tube corresponding to this suspended portion. At this time, when the electromagnet is not working, the fluid flows around the inside of the tube, but when the electromagnet is working, the bag portion that seals the magnetic fluid expands toward the surrounding inner wall of the tube, blocking the flow. It acts as a variable orifice.
