<P>PROBLEM TO BE SOLVED: To provide a solenoid valve whose manufacturing cost can be further reduced by improving the rate of commonalizing N/C and N/O type components. <P>SOLUTION: A flow path control part 10 is configured to be commonalized to the N/C and N/O type solenoid valves 1, 2, and an electromagnetic part 20 is configured so that a case 21, a coil 22, and first and second yokes 23, 25 can be commonalized to the N/C and N/O type solenoid valves 1, 2. At least one of the cases can be established that the N/C type solenoid valve 1 is configured in which a compression spring 29 is provided for energizing a plunger 24 to the side of the flow path control part 10 during deenergizing the coil 22 to thrust a ball valve 14 via a first shaft 28a on a first valve seat 12a, and that the N/O type solenoid valve 2 is configured in which the plunger 24 is sucked to the side of the flow path control part 10 during energizing the coil 22 to thrust the ball valve 14 via a second shaft 28b on the first valve seat 12a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
