Abstract

Ein Brennstoffeinspritzventil (1) für Brennstoffeinspritzanlagen von Brennkraftmaschinen umfaßt eine Magnetspule (10), eine mit der Magnetspule (10) in Wirkverbindung stehende und in einer Schließrichtung von einer Rückstellfeder (23) beaufschlagte Ventilnadel (3) zur Betätigung eines Ventilschließkörpers (4), der zusammen mit einer an einem Ventilsitzkörper (5) ausgebildeten Ventilsitzfläche (6) einen Dichtsitz bildet, und zumindest eine Abspritzöffnung (7), die in dem Ventilsitzkörper (5) ausgebildet ist. Die Abspritzöffnungen (7) sind von Erhebungen (38) umfaßt, welche eine innere Stirnseite (37) des Ventilsitzkörpers (5) überragen und sich im geschlossenen Zustand des Brennstoffeinspritzventils (1) in Anlage an dem Ventilschließkörper (4) befinden.
