Abstract
Hochdruckanschluss für ein Kraftstoffeinspritzsystem für Brennkraftmaschinen, mit einer Hochdruckleitung, die an ihrem Ende ein mit dieser fest verbundenes vergrößertes Endstück aufweist, das durch eine mit einem ortsfesten Teil verschraubte Hohlschraube auf eine Dichtfläche dieses ortsfesten Teiles gepresst ist, dadurch gekennzeichnet, dass das Endstück durch ein die Hohlschraube (5) umgebendes Ringstück (4) gebildet ist, dessen jeweilige Stirnfläche (4a; 4b) sich dem Schraubenkopf und dem ortsfesten Teil (2) zugewandt verjüngend ausgebildet ist und in entsprechend angepasste Ringnuten (10, 11) des Schraubenkopfes (5a) und des ortsfesten Teiles (2) hineindrückbar ist.High-pressure connection for a fuel injection system for internal combustion engines, having a high-pressure line having at its end a permanently connected thereto enlarged end piece, which is pressed by a bolted to a stationary part of a hollow screw on a sealing surface of this stationary part, characterized in that the tail by a the hollow screw (5) surrounding ring piece (4) is formed, the respective end face (4a, 4b) is tapered facing the screw head and the stationary part (2) and in correspondingly adapted annular grooves (10, 11) of the screw head (5a) and the stationary part (2) is hineindrückbar.
Description
Die Erfindung betrifft einen Hochdruckanschluss für ein Kraftstoffeinspritzsystem für Brennkraftmaschinen mit den aus dem Oberbegriff des Patentanspruchs 1 angegebenen Merkmalen.The invention relates to a high-pressure connection for a Fuel injection system for Internal combustion engines with those from the preamble of the claim 1 specified characteristics.
Aus der
Eine Ausführung dieser Art erfordert einen großen Platzbedarf in der Höhe.An execution of this kind requires a big Space required in height.
Aus der
Eine Ausführung dieser Art ist nur für einen Niederdruckanschluss geeignet.An embodiment of this type is only for a low pressure connection suitable.

Der Erfindung liegt die Aufgabe zugrunde, durch einfache Maßnahmen einen Hochdruckanschluss zu schaffen, der neben einer niedrigen Bauhöhe auch eine leckagefreie Abdichtung bei Drücken von über 1500 bar ermöglicht.The invention is based, by simple measures to create a high pressure connection, in addition to a low height also allows a leak-free sealing at pressures of over 1500 bar.
Zur Lösung dieser Aufgabe dienen die im kennzeichnenden Teil des Anspruchs vorgesehenen Merkmale.To solve this task the features provided in the characterizing part of the claim.
In den Unteransprüchen sind noch förderliche Weiterbildungen der Erfindung angegeben.In the dependent claims are still beneficial Developments of the invention indicated.
Durch die seitliche Zuführung der Hochdruckleitung mit ihrem besonderen Ringstück ergibt sich eine kompakte Bauweise des Hochdruckanschlusses. Die Stirnflächen des Ringstückes und die als Gegenstücke wirkenden Ringnuten im Schraubenkopf der Hohlschraube und in dem ortsfesten Teil sind so gestaltet, dass sich beim Verschrauben ein Formschluss mit einer besonderen Abdichtungswirkung ergibt, die sich im Betrieb durch den herrschenden Innendruck noch verstärkt.By the lateral supply of High-pressure line with its special ring piece results in a compact Construction of the high-pressure connection. The end faces of the ring piece and as counterparts acting annular grooves in the screw head of the hollow screw and in the fixed part are designed so that when screwing a positive connection with a special sealing effect that results in operation reinforced by the prevailing internal pressure.
