Abstract

Ein Brennstoffeinspritzventil (1), das insbesondere als Injektor für Brennstoffeinspritzanlagen von luftverdichtenden, selbstzündenden Brennkraftmaschinen dient, umfasst ein Gehäuseteil (3), einen Steuerventilkörper (11), der in einem Steuerventilraum (9) des Gehäuseteils (3) angeordnet ist, und eine Dichthülse (20), die an dem Steuerventilkörper (11) angeordnet ist. Dabei wirkt die Dichthülse (20) mit einer Ventilsitzfläche (11) zu einem Dichtsitz (22) zusammen. Ferner weist der Steuerventilkörper ein Außengewinde (27) auf. Und die Dichthülse (20) weist ein Innengewinde (28) auf. Hierbei steht das Außengewinde (27) des Steuerventilkörpers (11) mit dem Innengewinde (28) der Dichthülse (20) in einem Eingriff. Hierdurch ist ein Leckagepfad zwischen dem Steuerventilkörper (11) und der Dichthülse (20) verlängert.
