Abstract
A novel fuel injection valve including an armature which has a through bore, which communicates with a blind bore formed concentrically with a longitudinal valve axis in a ball serving as the valve closing body, and at least one transverse conduit begins at this blind bore and extends to an outer surface of the ball. The fuel reaches the valve seat through the through bore, the blind bore and the at least one transverse conduit. This results in an especially compact embodiment of the fuel injection valve according to the invention. The fuel injection valve is especially well-suited to fuel injection systems of mixture-compressing internal combustion engines with externally supplied ignition.
