PROBLEM TO BE SOLVED: To provide a duplex solenoid valve enabling two valves to be changed over by a single solenoid and enabling its size to become small and its energy saving to be attained.SOLUTION: This invention comprises: each of first and second movable iron cores 3, 3having each of first and second valves 2, 2at one end; each of first and second guide cylinders 4, 4having each of the movable iron cores slidably inserted into it; each of first and second fixed iron cores 5, 5arranged at the other end of each of the guide cylinders so as to be oppositely faced against each of the movable iron cores; a first frame 8arranged to connect both fixed iron cores; a second frame 8arranged to connect one end of each of both guide cylinders; and a single solenoid 9 arranged to enclose one of both guide cylinders. Energization of the solenoid 9 causes each of the first and second movable iron cores 2, 2to be attracted and moved toward each of the fixed iron cores 5, 5and then each of the valves 2, 2is changed over in operation. |
