Abstract
Description
Die Erfindung geht aus von einem Brennstoffeinspritzventil nach der Gattung des Hauptanspruchs.The The invention is based on a fuel injection valve after Genus of the main claim.
Beispielsweise
ist aus der
Nachteilig bei dem aus der obengenannten Druckschrift bekannten Brennstoffeinspritzventil ist insbesondere, daß viele Bauteile benötigt werden, um die Massen von Anker und Ventilnadel zu entkoppeln und dadurch ungewollte Nacheinspritzungen zu vermeiden.adversely in the fuel injection valve known from the above publication in particular, that many Components needed be used to decouple the masses of armature and valve needle and thereby avoid unwanted post-injection.
Vorteile der ErfindungAdvantages of invention
Das erfindungsgemäße Brennstoffeinspritzventil mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß durch einen zwischen dem Anker und dem Düsenkörper angeordneten magnetischen Stützring ein nachträgliches Öffnen des Brennstoffeinspritzventils verhindert werden kann. Das Brennstoffeinspritzventil wird entprellt. Zudem kann der Verschleiß verschiedener Anschlagflächen im Brennstoffeinspritzventil vermindert werden.The Fuel injection valve according to the invention with the characterizing features of the main claim has the Advantage that through an arranged between the armature and the nozzle body magnetic support ring a subsequent opening of the Fuel injector can be prevented. The fuel injector is debounced. In addition, the wear of various stop surfaces in Fuel injector can be reduced.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterentwicklungen des im Hauptanspruch angegebenen Brennstoffeinspritzventils möglich.By in the subclaims listed activities are advantageous developments of the specified in the main claim Fuel injection valve possible.
Von Vorteil ist außerdem, daß der Stützring aus zwei Ringen und einem dazwischenliegenden Steg ausgebildet ist, in dessen Bereich die Wandstärke des Stützrings geringer ist als in den beiden Ringen. Dadurch geht das Magnetfeld schnell in Sättigung.From Another advantage is that the Support ring off two rings and an intermediate bridge is formed, in its area the wall thickness of the support ring less than in the two rings. This is the magnetic field fast in saturation.
Vorteilhafterweise untergreift der Stützring den Außenpol der Magnetspule und ist dadurch gehäusefest angeordnet.advantageously, engages under the support ring the outer pole the solenoid and is thus fixed to the housing.
Weiterhin ist von Vorteil, daß der Stützring aus einem Material gefertigt ist, welches auch nach dem Abbau des Magnetfeldes eine Restmagnetisierung behält.Farther is an advantage that the Support ring off made of a material which also after the degradation of the magnetic field Remains a residual magnetization.
