Abstract:
A fuel injection valve having a longitudinal valve axis, comprising:a magnet coil;an integrally formed metal internal pole;an integrally formed metal valve jacket radially surrounding the metal internal pole, a clearance being formed between the metal valve jacket and the metal internal pole, the magnet coil being inserted in the clearance, the magnet coil being completely surrounded by the metal valve jacket in a peripheral direction, the metal internal pole and the metal valve jacket together delimiting the clearance axially above and below the magnet coil, a first metallic contact being established substantially circumferentially between the metal internal pole and the metal valve jacket above the magnet oil and a second metallic contact being established substantially circumferentially between the metal internal pole and the metal valve jacket below the magnet coil, the metal internal pole and the metal valve jacket being fixedly connected to one another at least in one of the first metallic contact and the second metallic contact;an armature; anda valve closing body working together with a fixed valve seat face and being operated by the armature;wherein the magnet coil, the metal internal pole, the metal valve jacket and the armature form an electromagnectic circuit.
