Abstract
PURPOSE: To obtain a compact and economical change-over valve, by disposing slidable permanent magnets on the opposite sides of a fixed iron core that is fixed on the inside of a coil bobbin, and opening and closing valves selectively through the movement of said permanent magnets.
CONSTITUTION: In an inner chamber 21 of a body 17, there is disposed a magnetic yoke 23 which is supported axially by a spring 22. Inside the yoke 23, a bobbin 25 having electromagnetic coil 24 wound therearound is fixed together with support members 26, 26'. A fixed iron core 28 is supported on the inside of the bobbin 25, and laterally slidable permanent magnets 27, 27' are fitted respectively on the inside of the support members 26, 26'. Further, on the opposite sides of the body 17, there are disposed valve bodies 31, 34 which are opened and closed through movement of permanent magnets 27, 27'. With such an arrangement, when current is passed through the coil 24, one permanent magnet 27 is moved by the reaction force and forces the valve body 31 open, while the other magnet 27' is attracted by iron core 28. When the direction of current flow is reversed, the above operation is also reversed.
