Die Erfindung geht aus von einem Kraftstoffeinspritzmodul nach der Gattung des Patentanspruchs 1.The The invention is based on a fuel injection module of the type of claim 1

Düsenspannmutter
Vorteile der ErfindungAdvantages of invention
Das erfindungsgemäße Kraftstoffeinspritzmodul für Brennkraftmaschinen mit den kennzeichnenden Merkmalen des Patentanspruchs 1 hat demgegenüber den Vorteil, dass auch bei hohen Drücken die Dichtheit der miteinander verpressten Bauteile gegeben ist. Die Erfindung teilt die bekannte Düsenspannmutter in zwei Spannmuttern auf, sodass die Verformung des ersten Modulkörpers auf ein Minimum reduziert wird. Das Kraftstoffeinspritzmodul wird gleichmäßig verspannt, da jede Schnittstelle für sich verspannt wird. Der Düsenkörper trifft rechtwinklig auf die Drosselplatte, die Dichtheit ist gegeben. Durch die gleichmäßige Einleitung der axialen Spannkraft werden die Flächenpressungen zwischen den Bauteilen gleichmäßiger, was zu einer höheren Hochdruckdichtheit führt. Durch die Aufteilung in zwei Spannmuttern können relativ kurze Spannmuttern realisiert werden, was die technische Umsetzung einfach und kostengünstig macht; zudem sind bessere Fertigungstoleranzen zu realisieren. Die Spannmuttern werden vorzugsweise als Tiefziehteile realisiert, um eine kostengünstige Lösung zu realisieren.The Fuel injection module according to the invention for internal combustion engines with the characterizing features of claim 1 has the other hand Advantage that even at high pressures the Tightness of the compressed components is given. The Invention shares the known nozzle retaining nut in two clamping nuts, so that the deformation of the first module body on a minimum is reduced. The fuel injection module is tensioned evenly, there every interface for yourself is strained. The nozzle body hits perpendicular to the throttle plate, the tightness is given. By the even introduction the axial clamping force, the surface pressures between the Components more uniformly, what to a higher high pressure tightness leads. Due to the division into two clamping nuts, relatively short clamping nuts can be used be realized, which makes the technical implementation easy and inexpensive; In addition, better manufacturing tolerances are to be realized. The clamping nuts are preferably realized as deep-drawn parts to a cost-effective solution realize.
Weitere Vorteile und vorteilhafte Ausgestaltungen des Gegenstands der Erfindung sind der Beschreibung, der Zeichnung und den Ansprüchen entnehmbar.Further Advantages and advantageous embodiments of the subject invention are the description, the drawings and the claims removable.
