Ein derartiger Kraftstoffhochdruckspeicher ist z.B. in derSuch a high-pressure fuel accumulator is e.g. in the
EP 0 866 221 AI beschrieben. In Common-Rail - Einspritzsystemen fördert eine Hochdruckpumpe, eventuell unter Zuhilfenahme einer Vorförderpumpe , den einzuspritzenden Kraftstoff aus einem Tank in den zentralen Kraftstoffhochdruckspeicher, der als Common-Rail bezeichnet wird.

In common-rail injection systems, a high-pressure pump, possibly with the aid of a prefeed pump, conveys the fuel to be injected from a tank into the central high-pressure fuel reservoir, which is referred to as the common rail. Fuel lines lead from the rail to the individual injectors, which are assigned to the cylinders of the internal combustion engine. Depending on the operating parameters of the internal combustion engine, the injectors are individually controlled by the engine electronics in order to inject fuel into the combustion chamber of the internal combustion engine.
Aufgabe der Erfindung ist es, die Qualität und die Sicherheit an den Hochdruckanschlussstellen bei einemThe object of the invention is to improve the quality and safety at the high-pressure connection points
Kraftstoffhochdruckspeicher der eingangs geschilderten Art zu verbessern. Außerdem soll der erfindungsgemäße Kraftstoffhochdruckspeicher einfach aufgebaut und kostengünstig herstellbar sein.To improve high-pressure fuel storage of the type described. In addition, the invention High-pressure fuel storage can be constructed simply and inexpensively manufactured.
Die Aufgabe ist bei einem Kraftstoffhochdruckspeicher für ein Common-Rail-Kraftstoffeinspritzsystem einerIn a high-pressure fuel accumulator for a common rail fuel injection system, the task is one
Brennkraftmaschine, mit einem rohrförmigen Grundkörper an den mindestens eine Buchse zum Anschließen einer Hochdruckleitung angeschweißt ist, dadurch gelöst, dass an dem zum Grundkörper gewandten Ende der Buchse ein Bund ausgebildet ist.Internal combustion engine, with a tubular base body welded to the at least one socket for connecting a high-pressure line, is achieved in that a collar is formed on the end of the socket facing the base body.
Vorteile der ErfindungAdvantages of the invention
Der Bund dient zum Einbringen des zum Anschweißen der Buchse erforderlichen Schweißstroms. Bei herkömmlichenThe collar serves to introduce the welding current required to weld the socket. With conventional
Buchsen ohne Bund wird die Schweißelektrode an dem von dem Grundkörper abgewandten Ende der Buchse angelegt. Dabei können Schweißspritzer in das Innere der Buchse gelangen und ein dort vorgesehenes Gewinde beschädigen. Außerdem kann sich die Geometrie im Inneren der Buchse aufgrund der beim Schweißen auftretenden Temperaturen in unerwünschter Weise verformen. Diese Nachteile werden durch die Bereitstellung des erfindungsgemäßen Bundes als Angriffsstelle für eine Schweißelektrode vermieden. Ein weiterer Vorteil ist darin zu sehen, dass der Bund eine Angriffsfläche für eine Kraft bildet, mit der die Buchse beim Schweißen gegen den Grundkörper gedrückt wird. Eine solche Kraft kann praktischerweise auch mit der Schweißelektrode aufgebracht werden.Sockets without a collar, the welding electrode is placed on the end of the socket facing away from the base body. Spatter can get inside the socket and damage a thread provided there. In addition, the geometry inside the socket can undesirably deform due to the temperatures that occur during welding. These disadvantages are avoided by the provision of the collar according to the invention as a point of attack for a welding electrode. Another advantage can be seen in the fact that the collar forms a contact surface for a force with which the bush is pressed against the base body during welding. Such a force can conveniently also be applied with the welding electrode.
Eine besondere Ausführungsart der Erfindung ist dadurch gekennzeichnet, dass von dem Innenraum des rohrförmigen Grundkörpers eine Bohrung ausgeht, die in einen Aufnahmetrichter mündet, der sich nach außen hin erweitert und zur Aufnahme eines Endes der Hochdruckleitung dient, das durch eine im Wesentlichen hohlzylinderförmige Pressschraube hochdruckdicht gegen den Aufnahmetrichter gepresst wird, und dass die Dichtstelle von einem im Wesentlichen hohlzylinderförmigen Isolierring umgeben ist. Durch den Isolierring wird ein elektrischer Nebenschluss beim Anschweißen der Buchse sicher verhindert. Außerdem gewährleistet der Isolierring, dass beim Anschweißen der Buchse keine Schweißspritzer zur Dichtstelle gelangen können.A special embodiment of the invention is characterized in that a bore extends from the interior of the tubular base body, which opens into a receiving funnel, which widens outwards and serves to receive one end of the high-pressure line, which is formed by a substantially hollow cylindrical Press screw is pressed against the receiving funnel in a high pressure-tight manner, and that the sealing point is surrounded by an essentially hollow cylindrical insulating ring. The insulating ring reliably prevents an electrical shunt when the socket is welded on. In addition, the insulating ring ensures that no welding spatter can get to the sealing point when the bushing is welded on.
Eine weitere besondere Ausführungsart der Erfindung ist dadurch gekennzeichnet, dass der Isolierring in die Buchse vormontiert ist, und dass die innere Mantelfläche des Isolierrings an der äußeren Mantelfläche eines Vorsprungs anliegt, in dem der Aufnahmetrichter ausgebildet ist. Dadurch wird erreicht, dass die Buchse bei der Montage vor dem Anschweißen relativ zu dem Vorsprung zentriert wird.A further special embodiment of the invention is characterized in that the insulating ring is preassembled in the socket and that the inner lateral surface of the insulating ring rests on the outer lateral surface of a projection in which the receiving funnel is formed. This ensures that the bushing is centered relative to the protrusion during assembly before welding.
Eine weitere besondere Ausführungsart der Erfindung ist dadurch gekennzeichnet, dass das Ende der Hochdruckleitung kugelig ausgebildet ist, und dass der Innendurchmesser der Pressschraube größer als der Außendurchmesser der Hochdruckleitung ist. Dadurch wird eine Freistellung der Hochdruckleitung relativ zu der Buchse ermöglicht. Das liefert den Vorteil, dass eventuelle Einbautoleranzen im Motorraum ausgeglichen werden können.A further special embodiment of the invention is characterized in that the end of the high pressure line is spherical and that the inside diameter of the compression screw is larger than the outside diameter of the high pressure line. This enables the high-pressure line to be released from the socket. This has the advantage that any installation tolerances in the engine compartment can be compensated for.
Eine weitere besondere Ausführungsart der Erfindung ist dadurch gekennzeichnet, dass die zu dem rohrförmigen Grundkörper gewandte Stirnseite der Buchse nach innen abgeschrägt ist. Durch die Abschrägung wird der Zugang zu der Verbindungsstelle zwischen der Buchse und dem rohrförmigen Grundkörper erleichtert.A further special embodiment of the invention is characterized in that the end face of the socket facing the tubular base body is chamfered inwards. The beveling facilitates access to the connection point between the socket and the tubular base body.
