Abstract

Ein Brennstoffeinspritzventil (1), insbesondere zum direkten Einspritzen von Brennstoff in einen Brennraum einer Brennkraftmaschine, umfaßt einen Aktor (10), der mit einer Ventilnadel (3) in Wirkverbindung steht, wobei die Ventilnadel (3) an ihrem abspritzseitigen Ende einen Ventilschließkörper (4) aufweist, der mit einer Ventilsitzfläche (6), die an einem Ventilsitzkörper (5) ausgebildet ist, zu einem Dichtsitz zusammenwirkt. Ferner ist eine Drallscheibe (36) vorgesehen, in der Drallkanäle (38) ausgebildet sind. Die Drallscheibe (36) weist Fortsätze (39) auf, die mit einer Nockenscheibe (37) so zusammenwirken, daß eine Tangentialkomponente des durch die Drallscheibe (36) erzeugten Dralls veränderbar ist.
