を特徴とす 。 る電磁燃料噴射器。[Claims for Utility Model Registration] A cylindrical valve housing with a fuel injection port and a valve seat at one end and an open end at the other end, and a valve at the front end that can reciprocate within the valve housing. an on-off valve that is inserted into the valve and is normally biased by a compression spring to close the fuel injection port; a movable iron core that is connected to the rear end of the on-off valve; and a cylindrical valve that has a front end facing the movable iron core. A fixed iron core, an electromagnetic coil wound around the outer peripheral surface of the fixed iron core, and the valve.
The electromagnetic fuel injector for an internal combustion engine is composed of a housing and a magnetic case that houses and fixes the fixed core, and when the electromagnetic coil receives a signal, the fuel injection port opens and pressurized fuel is injected. The magnetic pole portion of the iron core, the fixed iron core, and at least one of the iron cores of the magnetic case is characterized in that the magnetic pole portions of the iron core, the fixed iron core, and the magnetic case are formed by forming plate-shaped magnetic bodies in layers parallel to the magnetic flux direction. electromagnetic fuel injector.
