Abstract

Kraftstoffeinspritzventil mit einem Düsenkörper (300), der eine zentrale Führungsbohrung (312) und seitlich zur Führungsbohrung (312) einen Zulaufkanal (338) aufweist, die beide in einen Druckraum (334) münden und zwischen denen eine Zwischenwand (346) mit einer geringsten Wandstärke liegt. Der Düsenkörper (300) weist an seinem stirnseitigen Ende einen Absatz auf, wodurch der Zulaufkanal (338) steiler in den Druckraum (334) ragt und somit die Wandstärke größer ist. Dadurch wird eine größere Druckfestigkeit des Düsenkörpers (300) erreicht.
