Abstract

Die Erfindung betrifft einen Düsenkörper mit einer um eine Längsachse angeordneten Düsennadelausnehmung, umfassend einen konischen Düsennadelsitz, welcher in ein Sackloch mündet, sowie mindestens ein Einspritzloch, welches sich von dem Sackloch zu einer Außenoberfläche des Düsenkörpers erstreckt. Das Sackloch weist am Übergang zu dem konischen Düsennadelsitz einen Sacklochdurchmesser auf und erstreckt sich von dem Übergang in Achsrichtung bis zu einer Sacklochtiefe, wobei das Verhältnis von Sacklochdurchmesser zu Sacklochtiefe größer oder gleich 1,5 ist. Die Erfindung betrifft weiter eine Anordnung bestehend aus einem Düsenkörper und einer Düsennadel sowie einen Kraftstoffinjektor.
