Abstract
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einem Brennstoffeinspritzventil nach der Gattung des Anspruchs 1.The The invention is based on a fuel injection valve after Genus of claim 1.
Es sind bereits verschiedene Möglichkeiten zur Führung einer axial bewegbaren Ventilnadel in einem elektromagnetisch betätigbaren Brennstoffeinspritzventil bekannt, bei denen meist die obere Führung durch den Magnetanker in einem Gehäusebauteil übernommen wird, während die untere Ventilnadelführung üblicherweise im Bereich eines Ventilschließkörpers gegenüber einer inneren Öffnung eines Ventilsitzkörper vorgenommen wird. Für den Führungsbereich am Anker sind Ausführungen bekannt, bei denen der Führung dienende Funktionselemente entweder unmittelbar am geführten Anker oder am gegenüberliegenden starren führenden Ventilbauteil (Ventilsitzträger, Innenpol, Ventilhülse) oder an beiden Führungsbauteilen ausgebildet sind.It are already different ways to guide an axially movable valve needle in an electromagnetically actuated Fuel injector known in which mostly the upper guide taken over the armature in a housing component will, while the lower valve needle guide usually in the region of a valve closing body with respect to one inner opening a valve seat body is made. For the management area at the anchor are versions known in which the leadership serving functional elements either directly on the guided anchor or at the opposite rigid leading Valve component (valve seat carrier, Inner pole, valve sleeve) or on both guide components are formed.

Offenbarung der ErfindungDisclosure of the invention
Das erfindungsgemäße Brennstoffeinspritzventil mit den kennzeichnenden Merkmalen des Hauptanspruchs hat den Vorteil, dass eine optimale Führung der axial beweglichen Ventilnadel gewährleistet ist. In vorteilhafter Weise ist dazu in der äußeren Mantelfläche des auf der Ventilnadel angeordneten Ankers eine umlaufende Ringnut vorgesehen, in die ein Führungsring eingelegt ist. Der Führungsring stellt insofern ein separat gegenüber dem Anker herstellbares Bauteil dar, das in seinen Eigenschaften so optimiert ist, dass eine optimale Führung in der inneren Öffnung des führenden Ventilbauteils ermöglicht ist. Fertigungstechnisch kann die Führung somit sehr einfach und kostengünstig realisiert werden. Führungsringe lassen sich in großen Stückzahlen exakt reproduzierbar herstellen und bearbeiten.The Fuel injection valve according to the invention with the characterizing features of the main claim has the advantage that optimal leadership the axially movable valve needle is ensured. In an advantageous manner Way is to do so in the outer surface of the arranged on the valve needle armature a circumferential annular groove provided in which a guide ring is inserted. The guide ring presents insofar a separately opposite the armature manufacturable component that in its properties is optimized so that optimal guidance in the inner opening of the leading Valve component is enabled. Manufacturing technology, the leadership thus very easy and inexpensive will be realized. guide rings can be in big numbers produce and process exactly reproducible.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen Brennstoffeinspritzventils möglich.By in the subclaims listed activities are advantageous developments and improvements of the main claim specified fuel injector possible.
Besonders vorteilhaft ist es, eine solche kostengünstige verschleißfeste Ventilnadelführung in einem Brennstoffeinspritzventil zu realisieren, das insbesondere eine dünnwandige Ventilhülse besitzt, in der der Anker bzw. die Ventilnadel geführt wird.Especially It is advantageous to have such a low-cost wear-resistant valve needle guide in to realize a fuel injection valve, in particular a thin-walled one valve sleeve has, in which the armature or the valve needle is guided.
Weiterhin ist von Vorteil, dass der Führungsring aus einem Material mit martensitischem Gefüge hergestellt ist.Farther is an advantage that the guide ring made of a material with a martensitic structure.
Die erfindungsgemäße Führung der Ventilnadel lässt sich besonders wirksam bei sogenannten Ankerfreiwegkonstruktionen umsetzen, bei denen der Anker über einen bestimmten axialen Weg auf der Ventilnadel zur Prellervermeidung beweglich angeordnet ist.The inventive leadership of Valve needle leaves especially effective in so-called anchor freewheel constructions implement in which the anchor over a certain axial path on the valve needle to Prellervermeidung is movably arranged.
