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, und einer Drallvorrichtung (34). Die Drallvorrichtung (34) weist eine wendelförmige Wicklung (35, 42, 49) auf, die in Verbindung mit einer Ausnehmung (39, 46) des Ventilsitzkörpers (5) einen Brennstoffkanal (38) bildet, der Brennstoff auf einer Spiralbahn zu einer Abspritzöffnung (7) führt.
