A fuel injection valve (1), opening to the interior, with a stroke limitation, for fuel injection units in internal combustion engines, comprises a valve closing body (4), in working connection with a valve needle (3) and co-operating with a valve seating surface (6) on a valve seating body (5) to give a sealing seat. Downstream of the sealing seat an projection (34) is arranged on the valve closing body (4), comprising a sleeve-like section (36), extending through a through opening (37) in the valve seating body (5). The projection (34) comprises a radial extension (35) on the downstream end thereof, which has an axial separation from a locating face (32) in the valve seat body (5) and which is larger than the smallest radial extent of the through opening (37). |
