Abstract

Ein Brennstoffeinspritzventil für Brennstoffeinspritzanlagen von Brennkraftmaschinen umfasst ienen Ventilsitzkörper (5), dessen radiale Ausdehnung sich zumindest im Inneren in Strömungsrichtung verringert und in den eine Ventilsitzfläche (6) eigebracht ist, welche ,it einem Ventilschliesskörper (4), der ,it einer Ventilnadel (3) in Wirkverbindung steht, zu einem Dichtsitz zusammenwirkt und mehrere Abspritzöffnungen (7), deren ;ittelachsen (35) mit der Mittelachse (36) des Brennstoffeinspritzventils (1) einen von Null verschiedenen Winkel einschliessen. Der Abstand von der innenseite des Ventilsitzkörpers (5) zu der Oberfläche des Ventilschliesskörpers (4) vergrössert sich in stromabwärtiger Richtung von der Ventilsitzfläche (6) an und verkleinert sich weiter in stromabwärtiger Richtung wieder.
