Claims

[Scope of utility model registration request]

In the electromagnetic valve, a fixed core 5 is disposed on the inner circumferential side of a cylindrical coil 3, and a movable core 6 that moves forward and backward toward the fixed core 5 is disposed at one end of the fixed core 5 in the axial direction. a cylindrical portion 14a fixed to the inner circumferential side of the fixed iron core 5 and into which the movable iron core 6 is inserted in a movable manner; and a top plate portion fixed to one axial end of the fixed iron core 5 and integrally formed with the cylindrical portion 14a 14b, and a shield 14 made of a non-magnetic material in which a required number of fluid passage grooves 14d extending in the axial direction are formed on the inner circumferential surface of the cylindrical portion 14a.
