Abstract

Der Injektor weist ein Ventil (2) auf, das im geschlossenen Zustand den ersten Hochdruckbereich (H1) von einem ersten Niederdruckbereich (N1) trennt. Ferner weist der Injektor einen Aktor (1) auf, der das Ventil (2) ansteuert. Der Injektor ist derart ausgelegt, dass durch Öffnen des Ventils (2) ein Anheben einer Einspritznadel (E) zum Einspritzen von Kraftstoff bewirkt wird. Das Ventil (2) ist als Schieberventil ausgelegt.
