Title
(DE) Kraftstoffeinspritzventil
Abstract
(DE)

In einem Kraftstoffeinspritzventil, das in einer Brennkraftmaschine verwendet wird, wird eine Kraftstoffstrahl-Wegstrecke verkürzt. Es ist ein Kraftstoffeinspritzventil bereitgestellt, das ein Sitzelement umfasst, wobei das Sitzelement eine kegelförmige Sitzfläche, die Kraftstoff sitzt, indem sie in Kontakt mit einem Ventilkörper kommt, und Einlassöffnungsabschnitte mehrerer Kraftstoffeinspritzlöcher auf der kegelförmigen Sitzfläche umfasst und so ausgelegt ist, dass eine Achse des Einspritzlochs, die die Mitten eines Einlasses und eines Auslasses des Kraftstoffeinspritzlochs verbindet, entlang mehrerer kegelförmiger Flächen liegt, und wobei in einem Auslassquerschnitt, der aus einer Ebene gebildet ist, die parallel zu einem Einlassquerschnitt des Einlassöffnungsabschnitts des Kraftstoffeinspritzlochs ist, und an einem Auslass des Einspritzlochs angeordnet ist, das Sitzelement das Einspritzloch umfasst, in dem eine Hauptachsenrichtung einer Ellipse des Auslassquerschnitts einen Neigungswinkel von mehr als 0 Grad in Bezug auf eine gerade Linie in einer Kraftstoffeinspritzrichtung, die durch Projizieren einer Achse des Einspritzlochs auf den Auslassquerschnitt erhalten wird, und einen Neigungswinkel bis zu einem Ausmaß, das senkrecht zu der geraden Linie in der Kraftstoffeinspritzrichtung ist, aufweist.
