Electromagnetically actuated fuel injection valve

摘要

An electromagnetically actuatable fuel injection valve including a housing within which a magnetic core and winding are mounted along with an armature and a valve needle. The valve needle is provided at one end with an armature connection which fits within a bore of the armature. The armature connection is provided with a series of adjacent lands and grooves which are press-fitted with respect to the wall of the armature bore by a swaging tool. In this way a fixed and permanent bond is created between the valve needle and the armature.
