Abstract

Ein Brennstoffeinspritzventil (1), insbesondere zum direkten Einspritzen von Brennstoff in einen Brennraum einer Brennkraftmaschine, weist einen Aktor (10) zur Betätigung einer Ventilnadel (3) auf, wobei die Ventilnadel (3) an einem abspritzseitigen Ende einen Ventilschließkörper (4) aufweist, der zusammen mit einer Ventilsitzfläche (6), die an einem Ventilsitzkörper (5) ausgebildet ist, einen Dichtsitz bildet. In einer mit dem Ventilsitzkörper (5) verbundenen oder einstückig ausgebildeten Ventilnadelführung (31) sind Brennstoffkanäle (35) angeordnet, die in eine Drallkammer (43) münden. Die Anzahl der Brennstoffkanale (35) ist so bemessen, daß eine in der Drallkammer (43) erzeugte Drallströmung in einer Umfangsrichtung homogen ist.
