<p>PCT No. PCT/DE91/00152 Sec. 371 Date Nov. 13, 1991 Sec. 102(e) Date Nov. 13, 1991 PCT Filed Feb. 23, 1991 PCT Pub. No. WO91/14864 PCT Pub. Date Oct. 3, 1991.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.</p> |
