Claims

[Scope of utility model registration request]

A valve seat with a conical seating surface is formed at the front of the cylindrical valve seat, and a fuel injection hole is provided at the front end of the valve seat, which can reciprocate in the axial direction within the valve seat. An on-off valve consisting of a cylindrical slide member and a ball valve attached to its front end is inserted, and this on-off valve intermittently reciprocates due to the action of electromagnetic force and a spring to operate the ball valve. An electromagnetic fuel injector that opens and closes a fuel injection hole by detaching from and contacting a seat, and intermittently injects pressurized fuel from the fuel injection hole, wherein the front end of the slide member is attached to the outer surface of a ball valve. An electromagnetic fuel, characterized in that a ring-shaped contact part with a wide width is formed, and the front end of the contact part extends at least through the center of the ball valve to a plane perpendicular to the center line of the slide member. Injector.
