Description
Regelgestänge für Brennstoffeinspritzvorrichtungen fürControl linkage for fuel injectors for
Dieselmotoren.Diesel engines.
Die Erfindung bezieht sich auf ein Regelgestänge für Brennstoffeinspritzvorrichtungen für Dieselmotoren mit in wenigstens einer Reihe angeordneten Motorzylinder, von derjenigen Bauart, bei welcher Einspritzpumpe und Einspritzdüse zu einer je einem Motorzylinder zugeordneten Pumpe-Düse-Eiheit vereinigt sind, welche eine in die Pumpe-Düse-Einheit integrierte axial verschiebbare Regelstange aufweist, wobei die integrierten Regelstangen mit einer parallel zu ihnen liegenden axial verschiebbaren Hauptregelstange gekuppelt sind. Solche Pumpe-Düse-Einheiten müssen fallweise ausgebaut und gegebenenfalls ausgewechselt werden. Hiebei besteht bei den bekannten Anordnungen die Schwierigkeit, daß die Hauptregelstange ausgebaut werden muß. Dies erfordert nicht nur einen großen Arbeitsaufwand, sondern es besteht auch die Gefahr, daß die Einstellung der Regelung hiebei verändert wird. The invention relates to a control linkage for fuel injectors for diesel engines with engine cylinders arranged in at least one row, from of the type in which the injection pump and injection nozzle are each one Engine cylinder associated pump-nozzle unit are combined, which one in the Pump-nozzle unit has integrated axially displaceable control rod, the integrated control rods with an axially displaceable one lying parallel to them Main control rod are coupled. Such unit injectors have to be dismantled on a case-by-case basis and replaced if necessary. The known arrangements exist here the difficulty that the main control rod has to be removed. This requires not only a large amount of work, but there is also a risk that the The setting of the regulation is changed here.
Aufgabe der Erfindung ist es nun, bei einer solchen Anordnung den Ausbau und Wiedereinbau der Pumpe-Düse-Einheiten zu erleichtern, sowie neuerliche Einstellungsarbeiten nach dem Wiedereinbau von Pumpe-Düse-Einheiten entbehrlich zu machen. The object of the invention is now the with such an arrangement To facilitate removal and reinstallation of the unit injectors, as well as renewed ones Adjustment work is not necessary after reinstalling the unit injector close.
Zur Lösung dieser Aufgabe besteht die Erfindung im wesentlichen darin, daß in der Draufsicht in Achsrichtung der Pumpe-Düse-Einheit gesehen, kein Teil der Hauptregelstange und kein mit dieser verbundener Teil die Pumpe-Düse-Einheit oder einen mit dieser verbundenen Teil überdeckt, daß an der Hauptregelstange Klemmstücke angebracht sind, welche an den integrierten Regelstangen angreifen und daß jedes der Klemmstücke in einen Schlitz einer integrierten Regelstange eingreift, der senkrecht zur Achse derselben angeordnet ist. Es ist somit ein zeitraubender Ausbau der Hauptregelstange nicht erforderlich und es muß keine Verbindung des Regelgestänges gelöst werden. Es wird somit der Vorteil erreicht, daß die Einstellung der einzelnen Pumpe-Düse-Einheiten nicht verändert wird, da die Stellung der Hauptregelstange gegenüber dem Motorzylinderkopf erhalten bleibt. Wenn eine neue Pumpe-Düse-Einheit eingebaut werden soll, so kann die Einstellung dieser Pumpe-Düse-Einheit am Prüfstand erfolgen. Die in der Pumpe-Düse-Einheit integrierte Regelstange dient in üblicher Weise zur Einstellung einer oder mehrerer Betriebsgrößen, wie z.B. der Einspritzmenge und/oder des Einspritzbeginnes. Die an der Hauptregelstange angebrachten Klemmstücke, welche an den integrierten Regelstangen angreifen, erleichtern hiebei die korrekte Grundeinstellung und ermöglichen in Sonderfällen eine einfache nachträgliche Justierung, soweit eine solche überhaupt erforderlich wird. Dadurch, daß die Klemmstücke in einen Schlitz der integrierten Regelstange eingreifen, der senkrecht zur Achse derselben angeordnet ist, lassen sich die Pumpe-Düse-Einheiten ohne Schwierigkeiten in Achsrichtung der Pumpe-Düse-Baueinheiten abziehen und ebenso leicht wiederum unter neuerlichem Formschluß zwischen der integrierten Regelstange und dem Klemmstück wiederum einbauen.To solve this problem, the invention essentially consists in that seen in the plan view in the axial direction of the unit injector, no part the main control rod and no part connected to it is the unit injector or covers a part connected to this, that clamping pieces on the main control rod are attached, which attack the integrated control rods and that each the clamping piece engages in a slot of an integrated control rod, which is perpendicular is arranged to the axis of the same. It is therefore a time-consuming expansion of the main control rod not required and no connection of the control rod has to be released. The advantage is thus achieved that the setting of the individual pump-nozzle units is not changed because the position of the Main control rod opposite the engine cylinder head is retained. When a new unit injector is installed should be, the setting of this unit injector can be done on the test bench. The control rod integrated in the pump-nozzle unit is used in the usual way for Setting one or more operating parameters, such as the injection quantity and / or the start of injection. The clamping pieces attached to the main control rod, which Attacking the integrated control rods facilitate the correct basic setting and allow a simple subsequent adjustment in special cases, if one such is necessary at all. By the fact that the clamping pieces in a slot engage the integrated control rod, which is arranged perpendicular to the axis of the same is, the unit injectors can be without difficulty in the axial direction of the Pull off the pump-nozzle assemblies and just as easily again with a new form fit Install again between the integrated control rod and the clamping piece.
In der Zeichnung ist die Erfindung an Hand eines Ausführungsbeispieles dargestellt. In the drawing, the invention is based on an exemplary embodiment shown.
Fig. 1 zeigt eine Ansicht einer in den Motorzylinderkopf eingesetzten Pumpe-Düse-Einheit in Richtung des Pfeiles I der Fig. 2, Fig. 2 zeigt eine Ansicht in Richtung des Pfeiles II der Fig. 1, Fig. 3 zeigt einen Grundriß zu Fig. 1. Fig. 1 shows a view of an inserted into the engine cylinder head Pump-nozzle unit in the direction of arrow I in FIG. 2, FIG. 2 shows a view in the direction of arrow II in FIG. 1, FIG. 3 shows a plan view of FIG.
In der Pumpe-Düse-Einheit 1 ist eine Regelstange 2 axial verschiebbar geführt. Diese Regelstange 2 ist in die Pumpe-Düse-Einheit 1 integriert und bildet einen Teil derselben, welcher mit der Pumpe-Düse-Einheit 1 ausbaubar ist. Die Motorzylinder sind in Reihe angeordnet und jedem Motorzylinder ist eine eigene Pumpe-Düse-Einheit zugeordnet, welche in den Zylinderkopf 4 eingebaut ist. Die Pumpe-Düse-Einheit 1 ist mittels Schrauben 5 und Muttern 6, welche an einem Flansch 7 angreifen, mit dem Zylinderkopf 4 verspannt. A control rod 2 is axially displaceable in the pump-nozzle unit 1 guided. This control rod 2 is integrated into the pump-nozzle unit 1 and forms a part of the same, which can be removed with the pump-nozzle unit 1. The engine cylinders are arranged in series and each engine cylinder has its own unit injector assigned, which is installed in the cylinder head 4. The unit injector 1 is by means of screws 5 and nuts 6, which engage a flange 7, with the cylinder head 4 clamped.
Parallel zu den in die Pumpe-Düse-Einheiten 1 integrierten Regelstangen 2 ist eine Hauptregelstange 8 angeordnet, welche am Zylinderkopf 4 axial verschiebbar gelagert ist. Auf die Hauptregelstange 8 sind Klemmstücke 9 aufgeklemmt, welche mit Lappen 10 in einen Schlitz 11 der in die Pumpe-Düse-Einheit 1 integrierten Regelstangen 2 eingreifen, welcher senkrecht zur Achse der integrierten Regelstange 2 angeordnet ist. Durch diese Lappen 10 wird somit die integrierte Regelstange 2 bei der Verschiebung der Hauptregelstange 8 mitgenommen. Parallel to the control rods integrated in the unit injector 1 2, a main control rod 8 is arranged, which is axially displaceable on the cylinder head 4 is stored. On the main control rod 8 clamping pieces 9 are clamped, which with Tab 10 in a slot 11 of the control rods integrated in the pump-nozzle unit 1 2 intervene, which is arranged perpendicular to the axis of the integrated control rod 2 is. This tab 10 thus becomes the integrated control rod 2 during the displacement the main control rod 8 taken.
Die Anordnung ist so getroffen, daß in Achsrichtung der Pumpe-Düse-Einheit 1 gesehen, sich die Profile der Pumpe-Düse-Einheit und der nebenanliegenden Regelstange samt den damit verbundenen Bauelementen in keinem Punkt überschneiden. Auf diese Weise kann nach Lösung der Muttern 6 die Pumpe-Düse-Einheit 1 nach oben herausgehoben werden, ohne daß die Hauptregelstange 8 demontiert werden muß und ohne daß die Lage des Klemmstückes 9 und damit die Einstellung der Regelung verändert werden muß. The arrangement is made so that in the axial direction of the pump-nozzle unit 1, the profiles of the unit injector and the adjacent control rod including the associated components do not overlap at any point. To this Way, after loosening the nuts 6, the pump-nozzle unit 1 can be lifted upwards without the main control rod 8 having to be dismantled and without the location of the clamping piece 9 and thus the setting of the control must be changed.
Die Lage des Kipphebels 12, welcher durch einen Nocken 13 angetrieben wird, kann beim Ausbau der Pumpe-Düse-Einheit verändert werden, was aber nicht Gegenstand der vorliegenden Erfindung ist.The position of the rocker arm 12, which is driven by a cam 13 can be changed when removing the unit injector, but this is not the subject of this of the present invention.
