Claims

[Scope of utility model registration request]

When the solenoid valve coil 1 is energized, the plunger 2
In the solenoid valve, which is pulled up toward the attractor 3 side, the lower end surface of the attractor 3 made of non-magnetic material is positioned above the upper surface b14 of the housing 4, and the magnetic circuit is connected between the plunger 2 and the housing 4. By forming the closed circuit A, an air gap δ3 is generated between the lower end surface 16 of the attractor 3 and the upper end surface 15 of the plunger 2 even when electricity is applied, and the plunger 2 comes into contact with the attractor 3 made of a non-magnetic material. 1. A solenoid valve that eliminates impact noise when energized, characterized in that it is configured to prevent impact noise when energized.
