An electromagnetically actuated fuel injection valve includes a coaxial assembly of a connection tube, a bushing, a housing extension and a nozzle body. All seals between adjacent faces and edges of these elements are age-resistant metal-to-metal seals. The seal between the housing extension and the nozzle body is formed by pressing the overlapping end of the housing extension over annular edges on the nozzle body. The remaining seals are welds or solder-joints.

Electromagnetic fuel injection valve

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.
