  "textContent": "The present invention relates to an electromagnetic fuel injection valve (100) comprises a movable unit (12; 12A; 12B) having a valve element (S; 5A; 5B), an electromagnetic coil (2), 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 (1), which defines a fuel passage (f) extending axially through an injection valve body, a hollow seal ring (19) made of a nonmagnetic or a feeble magnetic material, a hollow nozzle housing (13), and a movable core (10) 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.",
