Abstract: A fuel injection valve for an internal combustion engine includes a movable armature including first and second armature parts, and a magnetic coil that generates a magnetic field for effecting an axial travel of the armature to displace a valve needle away from a closing position. During a first period of axial travel, the second armature part is axially displaced while the valve needle remains closed. During a subsequent second period of the axial travel, the first and second armature parts and the valve needle are fixed with respect to each other and travel axially with respect to the housing. During a third period of the travel, only the first armature part travels further towards the pole element for moving the valve needle further away from the closing position and the axial travel of the first armature part is subsequently stopped at the end of the third period.
