Abstract
A fuel injection valve includes a housing, a stator, a movable core, a coil, a nozzle hole, a valve member, and at least one communicating passage. The housing receives the stator and movable core. An end face of the movable core has a non-contact surface and a contact surface. The non-contact surface and the stator define a space when the contact surface contacts the stator. The valve member is slidably received in a bore of the movable core. The valve member has a stopper engageable with the movable core such that the valve member is axially movable together with the movable core. The at least one communicating passage connects the space with a corresponding one of a first fuel passage and a second fuel passage of the housing.
