Abstract

PURPOSE:In an electromagnetic valve equipped with a manual valve positioning mechanism, to maintain a valve at a position assumed when the solenoid is energized without continuously depressing a manual operating button by providing a locking mechanism capable of locking the button at two positions for the manual valve positioning mechamism. CONSTITUTION:When a push button 6 is pushed with a change lever 9 in stable state, the leg of the push button 6 slides along the slope of change lever 9 toward the side a so that the change lever 9 is turned clockwise about the pivot 13 lowering the side a. A push rod 11a slides along a push plate 10 toward the pivot 13, while a push rod 11b slides futher from the pivot 13. Thus the push plate 10 is turned clounterclockwise about a pivot 12 due to failure of the balance of force to push the main stem 2 of the electromagnetic valve to a position equivalent to the position assumed by the valve when the solenoid is energized. In this state the change lever 9, push plate 10 and the main stem 2 remain at the respective positions as described above if the push button is released, while only the push button 6 returned to its rest position by a spring 8.
