Abstract

Es wird ein Einspritzventil in Form einer Pumpe-Düse-Einheit mit einer Kühlleitung beschrieben, die eine effiziente Kühlung der Pumpe-Düse-Einheit ermöglicht und zudem eine Entkopplung von den Druckschwankungen der Pumpe-Düse-Einheit bewirkt. Die Kühlleitung ist an beiden Enden des Ventilgliedes des Steuerventils ausgebildet und vorzugsweise parallel zum Ventilglied angeordnet. Zudem wird durch die Kühlleitung das untere Aktorende gekühlt. Vorzugsweise weisen die Kühlleitung und die Kraftstoffleitung unterschiedliche Eingangsöffnungen auf.
