Abstract

Eine Kraftstoffeinspritzeinrichtung (1) umfasst einen Injektor (3') und ein Magnetventil (8) zur Steuerung des Einspritzvorgangs. Das Magnetventil (8) weist in seinem Innenraum mindestens einen ersten Strömungskanal zur Hindurchführung von Kraftstoff durch einen Ankerraum (16) des Magnetventils (8) und mindestens einen zweiten Strömungskanal zur Rückführung von Kraftstoff aus dem Magnetventil (8) heraus in Richtung Magnetventilöffnung auf. Der mindestens eine zweite Strömungskanal ist mit einer Kraftstoffrückführung in einen Kraftstofftank verbunden. Diese Strömungsführung gewährleistet eine Entlüftung des Ankerraums (16) bei Berücksichtigung eines möglichst geringen Bauraums der Kraftstoffeinspritzeinrichtung (1).
