PROBLEM TO BE SOLVED: To provide a double solenoid valve comprising each of first and second movable iron cores 3, 3having each of first and second valve bodies 2, 2connected to one end; each of first and second guide cylinders 4, 4having each of the movable iron cores slidably inserted therein; each of first and second fixed iron cores 5, 5arranged at the inner periphery of the other end of each of the guide cylinders; and each of first and second solenoid coils 7, 7enclosing each of the first and second guide cylinders 4,4so as to enable small-sized unit and electrical power saving to be attained.SOLUTION: There are provided a first magnetic plate 8at the other ends of both the first and second guide cylinders 4, 4and a second magnetic plate 8at one end of both guide cylinders 4, 4. A magnetic side plate for connecting both the first and second magnetic plates is eliminated so as to form a common magnetic passage 9 starting from the first movable iron core 3and returning to the first movable iron core 3through the first fixed iron core 5, the first magnetic plate 8, the second fixed iron core 5, the second movable iron core 3and the second magnetic plate 8.SELECTED DRAWING: Figure 2 |
