Electromagnetic valve

Abstract

Abstract PURPOSE: To improve responsibility and durability by making movable material as fluid composed of magnetic material. CONSTITUTION: A valve 10a is made of a spherical body whose magnetic material is composed of a movable material 10 guided to a penetrating bore 5a of a yoke 5 to form the magnetic passage inserted to the circumference of the opening edge of a frame 1, and of its spherical surface. Thus, when conduction to an exciting coil 2 is put ON, the movable material 10 is adhered to a valve seat 4b installed on a fixed iron core 4 resistingly to the thrust of a return spring 11, as with an effluent pipe 8 open, fluid flows out through an influent pipe 7 from the effluent pipe 8, at the same time as its weight is diminished because the movable material 10 is spherical body, flow resistance of fluid is dwindled. Further, the desired effect can be obtained since sliding of the movable material 10 to the penetrating bore 5a is linear contact and gets at reciprocation. COPYRIGHT: (C)1980,JPO&Japio
