Abstract
Description
Die
Erfindung geht aus von einer Kraftstoffeinspritzdüse nach
der Gattung des Patentanspruchs 1. Bei solch einer, z.B. durch die
Vorteile der ErfindungAdvantages of invention
Das erfindungsgemäße Kraftstoffeinspritzventil mit den kennzeichnenden Merkmalen des Patentanspruchs 1 hat demgegenüber den Vorteil, dass durch den Drosselring mit integrierter Drossel auf einfache Weise eine Kraftstoffeinspritzdüse mit Einspritzverlaufsformung erreicht werden kann. Bereits in Serie befindliche Kraftstoffeinspritzdüsen ohne Einspritzverlaufsformung können durch Einlegen des Drosselrings leicht nachgerüstet werden. Dabei kann der Öffnungshub der Ventilnadel, ab dem der zusätzliche Öffnungsquerschnitt freigegeben werden soll, leicht durch eine Einstellscheibe eingestellt werden, auf der der Drosselring im Ringraum gehäuseseitig anliegt.The Fuel injection valve according to the invention with the characterizing features of claim 1 has the other hand Advantage that through the throttle ring with integrated throttle on simple way a fuel injector with injection molding can be achieved. Already in series fuel injectors without injection molding can be easily retrofitted by inserting the throttle ring. In this case, the opening stroke the valve needle, from which the additional opening cross-section should be released, easily adjusted by a shim are on the throttle ring in the annulus on the housing side.
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.
