Abstract
A fuel injection valve that possesses an axially movable valve needle which includes at least one armature and one spherical valve closure element. The armature forms a closure element support which is joined at its downstream end to the valve closure element. The end of the closure element support facing toward the valve closure element is deformed in such a way that a polygonal profile is present. In accordance with the number of profile edges, at least two flowthrough openings, communicating with an inner longitudinal bore, are formed between the closure element support and the surface of the valve closure element, through which openings fuel can easily flow.
