| Summary: | An electromagnetic fuel injection valve comprises a movable unit having a valve element, an electromagnetic coil, and a magnetic circuit for magnetically attracting the movable unit toward a valve opening side through energization of the electromagnetic coil. The magnetic circuit is composed of a hollow, cylindrical stationary core, which defines a fuel passage extending axially through an injection valve body, a hollow seal ring made of a nonmagnetic or a feeble magnetic material, a hollow nozzle housing, and a movable core constituting a part of the movable unit. The stationary core and the nozzle housing are joined together through the seal ring. This electromagnetic fuel injection valve has improved responsibility. |
