摘要:
In electromagnetically actuatable valves having a core, surrounded by a magnet coil, and an armature that acts upon a valve closing body by means of a connecting tube, the connection between the connecting tube and the hard valve closing body is embodied by first providing the metallically harder closing body with a first spot weld, and after that this first spot weld is welded to the metallically softer connecting tube by means of a second spot weld, until the at least partly encompassing weld seam is formed between the valve closing body and the connecting tube, the weld seam assuring a safe and reliable connection. This embodiment of the valve is particularly well suited for injection valves of fuel injection systems.
