Abstract

Ein Brennstoffeinspritzventil (1) für Brennstoffeinspritzanlagen von Brennkraftmaschinen umfaßt einen Ventilschließkörper (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) in Strömungsrichtung nach dem Dichtsitz ausgebildet ist. Die Abspritzöffnung (7) ist in Strömungsrichtung verjüngt geformt, wobei ein Einlaufbereich (39) der Abspritzöffnung (7) abgerundet ist und einen größeren Öffnungswinkel aufweist als ein Auslaufbereich (42).
