发明名称 Fuel injection valve
摘要 A fuel injector, in particular for direct injection of fuel into the combustion chamber of a mixture-compressing, spark-ignited internal combustion engine, comprises an armature that coacts with a magnet coil, and comprises a valve needle, joined nonpositively to the armature, on which is provided a valve-closure member that, together with a valve-scat surface, forms a sealing scat. The valve needle has, at an inflow end, a collar-shaped armature stop, configured integrally with the valve needle, against which the armature comes to a stop, an engaging flange engaging through the armature in such a way that the engaging flange is insertable into the inflow end of the valve needle and is joinable thereto.
