Abstract
Description
Die Erfindung geht aus von einer Filteranordnung für einen Kraftstoffinjektor mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The invention is based on a filter arrangement for a Fuel injector with the features of the preamble of the claim 1.
Stand der TechnikState of the art
Bei
einer aus
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Filteranordnung zu schaffen, die ohne ein Einpressen in den Druckrohrstutzen des Kraftstoffinjektors auskommt und außerdem eine zuverlässige Filterwirkung aufweist.Of the present invention is based on the object, a filter assembly to create that without being pressed into the pressure pipe socket of the Fuel injector manages and also a reliable Has filter effect.
Darlegung der ErfindungPresentation of the invention
Die Aufgabe der Erfindung wird mit den kennzeichnenden Maßnahmen des Anspruchs 1 gelöst. Der Filterköper weist eine fingerförmige Ausbildung mit einem Flansch auf. Dadurch ist eine sichere und einfache Befestigungsmöglichkeit des Filterkörpers im Kraftstoff-Zulaufkanal des Kraftstoffinjektors möglich. Der Flansch dient dabei gleichzeitig als Dichtelement, das zwischen zwei Bauteilen hydraulisch dicht verklemmt wird. Ein spaltloses Einpressen des Filterkörpers in die Bohrung des Kraftstoff-Zulaufkanals kann somit entfallen.The The object of the invention is with the characterizing measures of claim 1. The filter body points a finger-shaped training with a flange. Thereby is a safe and easy way to attach the Filter body in the fuel inlet channel of the fuel injector possible. The flange serves at the same time as a sealing element, the between two components is hydraulically tightly clamped. A gapless one Press the filter body into the bore of the fuel inlet channel can thus be omitted.
Vorteilhafte Weiterbildungen der Erfindung sind durch die Maßnahmen der Unteransprüche möglich. Vorteilhaft ist es, wenn der fingerförmiger Abschnitt zumindest mit dem Filterabschnitt beabstandet von der Innenwand der Durchgangsbohrung im Druckrohrstutzen angeordnet ist. Eine vorteilhafte Ausführungsform besteht darin, indem der fingerförmige Abschnitt einen buchsenförmigen Abschnitt und einen napfförmigen Abschnitt aufweist und der Filterabschnitt am napfförmigen Abschnitt ausgebildet ist, wobei der Durchmesser des buchsenförmigen Abschnitts größer ist als der Durchmesser des napfförmigen Abschnitts. Zweckmäßig ist weiterhin, wenn der buchsenförmige Abschnitt einen Führungsabschnitt zur radialen Positionierung des Filterkörpers bildet.advantageous Further developments of the invention are by the measures the dependent claims possible. It is advantageous when the finger-shaped portion at least with the filter section spaced from the inner wall of the through hole in the pressure pipe socket is arranged. An advantageous embodiment exists therein, by the finger-shaped portion of a bush-shaped Section and having a cup-shaped portion and the filter section is formed on the cup-shaped section is, wherein the diameter of the bush-shaped section larger than the diameter of the cup-shaped Section. It is expedient if the bush-shaped section a guide section forms for the radial positioning of the filter body.
Der Flansch des Filterkörpers kann durch eine konisch verlaufende Wandung oder durch eine radial abstehende Wandung gebildet sein, wobei die radial abstehende Wandung gegenüber der Wandung des fingerförmigen Abschnitts eine verstärkte Dicke aufweisen kann. Die verstärkte Dicke kann dabei durch eine Materialverstärkung des Flanschs selbst und/oder durch eine Umbördelung der Wandung des Filterkörpers ausgeführt sein.Of the Flange of the filter body can be replaced by a conical Wall or be formed by a radially projecting wall, wherein the radially projecting wall opposite the wall of the finger-shaped portion has an increased thickness can have. The increased thickness can thereby by a Material reinforcement of the flange itself and / or by a flanging the wall of the filter body be executed.
