Claims

[Scope of utility model registration request]

(1) It is equipped with a fixed iron core 2 provided with a solenoid coil 1 and a movable iron core 3a that slides back and forth as the solenoid coil 1 is energized and demagnetized.
In this solenoid valve, the fluid passage 6 is opened and closed by seating or unseating the steel ball 7 on the valve seat 5, in which a spring 8 is interposed between the steel ball 7 and the movable iron core 3a. A solenoid valve featuring:

(2) With the steel ball 7 seated on the valve seat 5, the force of the spring 8 interposed between the steel ball 7 and the movable core 3a is applied to the seating of the spring 4 to cause the movable core 3a to separate from the fixed core 2. Scope of utility model registration claim 1 that is smaller than the force in the state
Solenoid valve described in section.
