Abstract (en)
[origin: WO2013178391A1] The invention relates to a fuel injector having an electromagnet 2 which contains a magnet core 6 and a coil 7 and which further has an armature 9 that is guided on an armature pin 8. The armature pin 8 is guided in a guide sleeve 11 which projects into the electromagnet 2. The fuel injector further has an injector body 4 with at least one injection opening which is introduced into the injector body 4 and which is controlled by an injector needle 5. The aim of the invention is to provide a fuel injector which is functionally improved with respect to the switching times of the fuel injector and the forces that can be generated in the fuel injector while simultaneously simplifying a guide sleeve for an armature pin. This is achieved in that the guide sleeve 11 is integrated into the magnet core 6 and is connected to the magnet core 6 in a formfitting or bonded manner. For this purpose, the guide sleeve 11 has widened sections 16 at both ends, said widened sections fixing the guide sleeve 11 in the magnet core 6.
