PURPOSE:To obtain a small-sized valve with small power consumption by elevating a valve body only with electromagnetic force. CONSTITUTION:When a coil body 8 is electrified, electromagnetic force is applied to the coil body 8. Accordingly, if the direction of an electric current to flow through the coil body 8 is that of the electromagnetic force required to raise the coil body 8 or the valve body 10, it is possible to open the valve by raising the valve body 10. If electrification of the coil body 8 is stopped, the valve body 10 is lowered by the actuation of a spring 9. Further, if the direction of the current is revered, it is also possible to lower the valve body 10 with electromagnetic force without use of the spring 9. |
