Abstract

Bei einem Kraftstoffeinspritzventil für Brennkraftmaschinen, mit einem an einem Ventilhaltekörper (7) festgespannten Ventilkörper (1), in dem ein Ventilglied (11) in einer Bohrung (9) axial verschiebbar geführt ist, wobei die Bohrung (9) einen radial erweiterten Druckraum (29) aufweist, in den wenigstens ein neben der Bohrung (9) verlaufender Zulaufkanal (37) mündet und mit einer Spannmutter (5), die mit einer inneren, konisch ausgebildeten Ringschulter (44) an einem in Höhe des Druckraumes (29) angeordneten Ringabsatz (45) des Ventilkörpers (1) anliegend diesen gegen den Ventilhaltekörper (7) verspannt, ist der Ringabsatz (45) auf seiner der Ringschulter (44) zugewandten Seite derart gekrümmt ausgebildet ist, daß sich in einem vorgegebenen Abstand (Rreib) von der Ventilgliedachse ein ringförmig umlaufender Auflagepunkt (60) ergibt, an dem die konische Ringschulter (44) im montierten Zustand anliegt.
