Abstract
Befestigungsvorrichtung zur wechselseitigen Befestigung eines Brennstoffeinspritzventils (1) in einer Ventilaufnahme (20) einer Brennkraftmaschine und des Brennstoffeinspritzventils (1) an einer Brennstoffverteilerleitung (4), wobei die Befestigungsvorrichtung (10) in Form einer Federklammer (11) ausgebildet ist, dadurch gekennzeichnet, daß die Federklammer (11) Federlaschen (14) umfaßt, welche wellenförmig ausgebildet sind und an einer Schulter (12) der Brennstoffverteilerleitung (4) anliegen und sich die Federlaschen (14) mit ihren Enden an Laschen (19) abstützen, die in die Federklammer (11) hineingebogen sind.Fastening device for the mutual fastening of a fuel injection valve (1) in a valve seat (20) of an internal combustion engine and the fuel injection valve (1) on a fuel distributor line (4), the fastening device (10) being designed in the form of a spring clip (11), characterized in that the spring clip (11) comprises spring clips (14) which are wave-shaped and bear against a shoulder (12) of the fuel distributor line (4) and the spring clips (14) are supported at their ends on clips (19) which are inserted into the spring clip ( 11) are bent into it.
Description
Stand der TechnikState of the art
Die Erfindung geht aus von einer Befestigungsvorrichtung zur Befestigung eines Brennstoffeinspritzventils in einem Zylinderkopf einer Brennkraftmaschine sowie zur Verbindung des Brennstoffeinspritzventils mit einer Brennstoffverteilerleitung nach der Gattung des Hauptanspruchs.The invention is based on a fastening device for fastening a fuel injection valve in a cylinder head of an internal combustion engine and for connecting the fuel injection valve with a fuel distributor line according to the preamble of the main claim.

Vorteile der ErfindungAdvantages of the invention
Die erfindungsgemäße Befestigungsvorrichtung für ein Brennstoffeinspritzventil mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß das Brennstoffeinspritzventil mit der Brennstoffverteilerleitung durch eine dazwischen eingespannte Federklammer mit Federlaschen zusammengehalten wird und demzufolge eine Befestigung des Brennstoffeinspritzventils am Zylinderkopf entfällt. Die Befestigungsvorrichtung sorgt durch die elastischen Federlaschen sowohl für einen Übertrag der Niederhaltekraft der Brennstoffverteilerleitung auf das Brennstoffeinspritzventil als auch für eine Toleranzen und Versätze ausgleichende flexible Fixierung.The fastening device according to the invention for a fuel injection valve with the characterizing features of the main claim has the advantage that the fuel injector is held together with the fuel distributor line by a spring clamp clamped therebetween with spring tabs and therefore eliminates attachment of the fuel injector on the cylinder head. The fastening device ensures through the elastic spring tabs both for a carryover of the hold-down force of the fuel distributor line to the fuel injection valve as well as for tolerances and offsets compensating flexible fixation.
Die wellenförmig ausgebildeten Federlaschen sind in einfacher Weise herstellbar und sorgen durch die elastische Verbindung mit der Federhülse für eine einfache Montage und eine sichere Verspannung der Bauteile.The wave-shaped spring tabs can be produced in a simple manner and ensure by the elastic connection with the spring sleeve for easy installation and secure clamping of the components.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Befestigungsvorrichtung möglich.The measures listed in the dependent claims advantageous refinements and improvements of the main claim fastening device are possible.
Von Vorteil ist insbesondere, daß sowohl die Befestigungsvorrichtung als auch die elastischen Federlaschen in einfacher Weise durch Stanzen aus Blech herstellbar sind. Auch eine Herstellung durch Tiefziehen und Stanzen ist möglich.A particular advantage is that both the fastening device and the elastic spring straps can be produced in a simple manner by punching sheet metal. A production by deep drawing and punching is possible.
Vorteilhafterweise entfallen bei der erfindungsgemäßen Befestigungsvorrichtung Schrauben oder Spannpratzen zur Befestigung an der Stirnseite des Zylinderkopfes. Advantageously, omitted in the fastening device according to the invention screws or clamps for attachment to the front side of the cylinder head.
Ausgestanzte Ausnehmungen und Hinterschnitte sorgen bei einfacher Herstellbarkeit vorteilhafterweise für eine sichere Fixierung der Befestigungsvorrichtung am Brennstoffeinspritzventil und an der Brennstoffverteilerleitung.Punched recesses and undercuts provide ease of manufacture advantageously for a secure fixation of the fastening device on the fuel injector and the fuel rail.

Zudem können durch die federnde Verspannung der Bauteile gegeneinander Fertigungstoleranzen und Längenänderungen durch Erwärmung beim Betrieb der Brennkraftmaschine ausgeglichen werden.In addition, by the elastic tension of the components against each other manufacturing tolerances and changes in length can be compensated by heating during operation of the internal combustion engine.
Die Erfindung ist nicht auf das dargestellte Ausführungsbeispiel beschränkt und beispielsweise auch für Brennstoffeinspritzventile
