Abstract
A fuel injection valve includes a valve member, a first stop member, a second stop member, a movable core, a fixed core, and a coil. The valve member opens and closes an injection nozzle. The first stop member protrudes radially outward from said valve member. The second stop member protrudes radially outward from said valve member. The movable core is sandwiched between said first and second stop members. The movable core and one of said first and second stop members defines a fuel chamber. The fixed core is axially displaced from said movable core. The coil causes reciprocal axial displacement of said valve member such that said movable core axially reciprocates toward and away from said fixed core therewith.
