Abstract

Ein Brennstoffeinspritzventil (1), insbesondere zum direkten Einspritzen von Brennstoff in einen Brennraum einer Brennkraftmaschine, umfaßt einen Ventilschließkörper (4), der zusammen mit einer Ventilsitzfläche (6), die an einem Ventilsitzkörper (5) ausgebildet ist, einen Dichtsitz bildet, eine Drallvorrichtung (34) mit Drallkanälen (35) und einen Abspritzkanal (7). Eine Längsachse (46) der in der Drallvorrichtung (34) ausgebildeten Drallkanäle (35) ist relativ zu einer Längsachse (38) des Abspritzkanals (7) so unter einem Winkel (δ) kleiner 90° orientiert, daß der das Brennstoffeinspritzventil (1) durchströmende Brennstoff eine Spiralbahn entlang einer Innenwandung (40) des Abspritzkanals (7) durchläuft.
