Claims

[Scope of utility model registration request]

A valve seat member with an opening formed in the center, a plate-shaped valve body made of a magnetic material that seats on this valve seat member and opens and closes the opening, and the outer periphery is fixed to the body side and the inner an annular stopper whose periphery is arranged to face the upper surface of the valve body;
A leaf spring is disposed overlapping the bottom surface of the stopper and presses the valve body in the seating direction, a solenoid sucks the valve body, and a plurality of nozzle holes are formed through the stopper to close the opening. An electromagnetic fuel injection valve equipped with a plate orifice, wherein the plate orifice is conical and the plurality of nozzle holes are formed through the conical plate orifice in a direction perpendicular to the conical surface of the conical plate orifice. Features an electromagnetic fuel injection valve.
