PURPOSE:To simplify the manual operation of the solenoid valve by a method wherein the main body of the valve is equipped with a push button device, supported slidably along the moving axial line of a movable iron core and equipped woth a pin projected from the main body of the valve. CONSTITUTION:When first cap 21 is pushed, the cap 21 is deformed by the elasticity thereof to push the pin 18, first valve body 13 is pressed against first valve seat 2 and the second valve body 14 is separated from the second valve seat 3, therefore, the first valve seat maintains a closed condition due to the force of a spring 20 and a hydraulic pressure. When the second cap 40 is pushed, the pin 39 with a flange is pushed and the movable iron core 32 is pushed toward first fixed iron core under the interposition of a push rod 38. At this time, a valve rod 16 is pushed to press the second valve body 14 against the second valve seat 3, the first valve seat 2 is released and this condition is maintained. |
