Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum zuführen von Kraftstoff zu Einspritzventilen einer Brennkraftmaschine mit einer Kraftstoffverteilerleitung und Ventiltassen zur Aufnahme jeweils eines Einspritzventiles, wobei die Ventiltassen außenseitig an der Kraftstoffverteilerleitung befestigt sind und wobei die jeweilige Ventiltasse jeweils über eine Verbindungsbohrung mit dem Inneren der Kraftstoffverteilerleitung in Verbindung steht.The The invention relates to a device for supplying fuel to injection valves an internal combustion engine with a fuel rail and Valve cups for receiving in each case an injection valve, wherein the valve cups on the outside the fuel rail are attached and wherein the respective Valve cup each over a connection bore with the interior of the fuel rail communicates.
Derartige Vorrichtungen sind in verschiedenen Ausgestaltungen bekannt. Bei Ottomotoren erfolgt die Kraftstoffverteilung über eine Kraftstoffverteilerleitung, wobei die Schnittstelle zwischen dem jeweiligen Einspritzventil und der Verteilerleitung üblicherweise über eine sogenannte Ventiltasse und einen sich am Einspritzventil befindlichen O-Ring verwirklicht ist.such Devices are known in various configurations. at Gasoline engines, fuel distribution takes place via a fuel rail, the interface between the respective injection valve and the distribution line usually via a so-called valve cup and located at the injection valve O-ring is realized.
Mit der Einführung von Benzinmotoren mit Direkteinspritzung (insbesondere unter hohem Druck) sind die Anforderungen an eine exakte Anordnung der Ventiltassen an der Kraftstoffverteilerleitung stark gestiegen, d.h. die Positionstoleranzen sind äußerst gering. Um diese Positionstoleranzen einhalten zu können, sind deshalb nur Vorrichtungen dieser Art be kannt, die aus massiven Konstruktionen bestehen, welche kosten- und gewichtsintensiv sind.With the introduction of gasoline engines with direct injection (especially under high pressure) are the requirements for an exact arrangement of the valve cups has risen sharply at the fuel rail, i. the positional tolerances are extremely low. To be able to comply with these positional tolerances are therefore only devices This type be known, which consist of massive constructions, which are cost and weight intensive.

Aufgabe der Erfindung ist es, eine derartige Vorrichtung so weiterzuentwickeln, dass sie mit möglichst geringem Herstellungsaufwand bei möglichst geringem Gewicht gleichwohl die geforderten Toleranzen bei der Anordnung der Ventiltassen zueinander einhält.task the invention is to develop such a device so that with you as possible low production costs with the lowest possible weight nonetheless the required tolerances in the arrangement of the valve cups to each other comply.
Diese Aufgabe wird mit einer Vorrichtung der eingangs bezeichneten Art erfindungsgemäß dadurch gelöst, dass wenigstens im Bereich der Ventiltassen an der Außenseite der Kraftstoffverteilerleitung ein streifenförmiges Fixierelement angeordnet ist, an welchem die Ventiltassen zusätzlich befestigt sind.These Task is with a device of the type described according to the invention thereby solved, that at least in the area of the valve cups on the outside the fuel distribution line is arranged a strip-shaped fixing element, on which the valve cups additionally are attached.
Bei einer solchen Vorrichtung sind die Ventiltassen somit nicht nur an der Kraftstoffverteilerleitung selbst befestigt und entsprechend ausgerichtet, sondern zusätzlich über ein streifenförmiges Fixierelement zueinander fixiert. Auf diese Weise ist es möglich, die geforderten Maßtoleranzen auch mit einer einfachen Blechkonstruktion einzuhalten, aufwendige und massive Konstruktionen wie beim Stand der Technik sind nicht erforderlich.at Such a device, the valve cups are thus not only attached to the fuel rail itself and accordingly aligned, but in addition to a strip-shaped Fixing fixed to each other. In this way it is possible the required dimensional tolerances to comply with a simple sheet metal construction, consuming and massive constructions as in the prior art are not required.
In vorteilhafter Ausgestaltung ist vorgesehen, dass das streifenförmige Fixierelement aus Blech besteht. Ein solches Fixierelement kann besonders einfach hergestellt werden.In Advantageous embodiment is provided that the strip-shaped fixing made of sheet metal. Such a fixing can be particularly simple getting produced.
Um die Ventiltassen am streifenförmigen Fixierelement festzulegen, kann nach einer Ausgestaltung vorgesehen sein, dass die Ventiltassen in Lochungen des streifenförmigen Fixierelementes eingesetzt sind.Around the valve cups on the strip-shaped Fixing set, can be provided according to an embodiment be that the valve cups in perforations of the strip-shaped fixing element are used.
Alternativ kann vorgesehen sein, dass das streifenförmige Fixierelement U- bzw. gabelförmige Aufnahmen aufweist, in welche die Ventiltassen eingesetzt sind.alternative can be provided that the strip-shaped fixing U- or bifurcated recordings has, in which the valve cups are used.
Neben der Fixierfunktion kann das streifenförmige Fixierelement auch dazu verwendet werden, die gesamte Vorrichtung am Motor zu befestigen, so dass zusätzliche Befestigungselemente entfallen können. Dazu ist vorgesehen, dass das streifenförmige Fixierelement mehrere Befestigungsbohrungen zur Befestigung an der Brennkraftmaschine aufweist.Next the fixing function, the strip-shaped fixing also to be used to attach the entire device to the engine, so that extra Fasteners can be omitted. For this purpose, it is provided that the strip-shaped fixing several Mounting holes for attachment to the internal combustion engine having.
In besonders vorteilhafter Ausgestaltung ist vorgesehen, dass das streifenförmige Fixierelement an der Kraftstoffverteilerleitung befestigt ist. Dazu ist das streifenförmige Fixierelement zur Befestigung an der Kraftstoffverteilerleitung bevorzugt abgewinkelt ausgebildet, was zum einen die Befestigung an der Kraftstoffverteilerleitung vereinfacht und zum anderen die Stabilität des streifenförmigen Fixierelementes erhöht.In Particularly advantageous embodiment is provided that the strip-shaped fixing the fuel rail is attached. This is the strip-shaped fixing preferably angled for attachment to the fuel rail, on the one hand the attachment to the fuel rail simplified and on the other hand, the stability of the strip-shaped fixing element elevated.
Alternativ kann aber auch vorgesehen sein, dass das streifenförmige Fixierelement nicht an der Kraftstoffverteilerleitung befestigt ist, sondern nur an den Ventiltassen.alternative but can also be provided that the strip-shaped fixing not attached to the fuel rail, but only at the valve cups.
Wie an sich bei derartigen Kraftstoffverteilersystemen üblich, ist bevorzugt vorgesehen, dass die Ventiltassen an der Kraftstoffverteilerleitung und am streifenförmigen Fixierelement angelötet sind.As is conventional in such fuel rail systems, is preferably provided that the valve cups on the fuel rail and at the strip-shaped Soldered fixing are.
