ELECTROMAGNETIC FUEL INJECTION VALVE

摘要

Provided is an electromagnetic fuel injection valve such that the collision faces of a chrome-coated movable element with respect to a stationary core and a valve body are flat, and change in the fuel injection quantity can be suppressed. The electromagnetic fuel injection valve is provided with a movable element having a cylindrical structure, and a valve body which is separated from the movable element and provided on the hollow portion side of the movable element so as to reciprocate. The movable element has a first collision face which collides with an end face of a stationary core, and a second collision face which collides with an end face of the valve body, said first collision face and second collision face coated with a chrome coating layer, and said chrome coating layer applied by disposing a positive electrode on the center axis of the movable element. An inclined face having an inclination to compensate for the inclination of the inclined face obtained from the thickness of the chrome coating layer gradually increasing toward the center axis is formed on the end face of the base material of the movable element on which at least one of either the first collision face or the second collision face will be formed. The chrome coating layer is applied on the inclined face, so that at least one of either the first collision face or the second collision face is flat.
