Abstract
A fuel injector for fuel injection systems of internal combustion engines and a method of manufacturing same are described. The fuel injector includes a valve seat body into which a valve seat face is introduced, which cooperates with a valve closing body to form a sealing seat, and a nozzle body to which the valve seat body is fixedly connected. The valve seat body is insertable into the interior of the nozzle body and on its downstream side it has a partially spherical outside geometry, which rests on a bearing surface of a seat body recess in the nozzle body. Valve seat body is mounted so it can rotate relative to the nozzle body on the bearing surface until its position is finally secured, and it may be aligned by a centering mandrel.
