Abstract

Regulator for injection pump controls arranged outside the cylinder crankcase such that pump controls for a single cylinder line are actuated by individual regulating levers on a shaft working with the pump regulator. The regulator shaft (14) should be inside the crankcase (12) which has an opening (13) alongside each injection pump (11) so the regulating lever (15) can be led out of the crankcase. A removable cover (17) closes off the functional connection between lever and pump control, (16) as also the crankcase opening (13) for protection. USE/ADVANTAGE - I.C. engines, fuel injection. Injection pump control uses fewer components in simply installed design protected from soiling.

Der Zweck einer derartigen Anordnung der Einspritzpumpen besteht darin, die Brennstoff-Einspritzleitungen zwischen den Einspritzpumpen und den Einspritzventilen an den Zylindern möglichst kurz ausbilden zu können.The purpose of such an arrangement of the injection pumps is in that the fuel injection lines between the Injection pumps and the injection valves on the cylinders to be able to train as short as possible.

Aus dem DE-GM 18 48 780 ist eine gattungsgemäße Reguliereinrichtung für einen Dieselmotor bekannt, bei der die Regulierdrehwelle mit den darauf befestigten Regulierhebeln außerhalb des Zylinder-Kurbelgehäuses angeordnet ist. Bei dieser offenen Bauweise ist die Regulierdrehwelle in Lagerböcken abgestützt, die auf dem Zylinder-Kurbelgehäuse ausgerichtet und befestigt werden müssen. Der Aufwand für Herstellung und Montage dieser bekannten Reguliereinrichtung ist hoch. Die offene Bauweise kann einerseits durch Verschmutzung zu Funktionsstörungen führen. Andererseits ist durch die ungeschützte Lage der Stelleinrichtungen die Möglichkeit von unerwünschter Manipulation von Einstellwerten gegeben.From DE-GM 18 48 780 is a generic Regulating device for a diesel engine known in which the Regulating rotary shaft with the regulating levers attached to it is arranged outside the cylinder crankcase. At this Open design is the regulating rotary shaft in bearing blocks supported, aligned and on the cylinder crankcase need to be attached. The effort for manufacturing and assembly this known regulator is high. The open one Construction can on the one hand due to pollution Cause malfunctions. On the other hand, through the unprotected position of the control devices the possibility of undesired manipulation of setting values.

Es ist Aufgabe der Erfindung, eine gattungsgemäße Reguliereinrichtung so weiterzubilden , daß sie einfach zu montieren ist und einen niedrigen Herstellungsaufwand ergibt.It is an object of the invention, a generic Regulating device so that it is easy to assemble and results in a low manufacturing cost.

Diese Aufgabe ist erfindungsgemäß mit den kennzeichnenden Merkmalen des Patentanspruchs gelöst.This task is according to the invention with the characteristic Features of the claim solved.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß eine Reduzierung der Zahl von Einzelteilen erreicht wurde und sich zusammen mit einer vereinfachten Montage ein niedriger Herstellungsaufwand für die Reguliereinrichtung ergibt, daß durch die verdeckte Bauweise der Reguliereinrichtung Funktionsstörungen durch Verschmutzungen vermieden sind, daß eine unerwünschte Manipulation von Einstellwerten zumindest erschwert ist und daß die Stelleinrichtung für Wartungszwecke doch leicht zugänglich bleibt.The advantages achieved with the invention exist in achieving a reduction in the number of parts was and together with a simplified assembly low manufacturing costs for the regulating device shows that due to the concealed construction of the regulator Malfunctions from contamination are avoided that an undesirable manipulation of setting values at least is difficult and that the actuator for maintenance purposes but remains easily accessible.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachstehend näher beschrieben.An embodiment of the invention is in the drawing shown and will be described in more detail below.

In Einsteckbauweise ausgebildete Einzeleinspritzpumpen 11 eines nicht weiter dargestellten Dieselmotors sind am Zylinder- Kurbelgehäuse 12 befestigt und werden von einer Nockenwelle 18 betätigt. Die an jeder der mit Schrägkantensteuerung arbeitenden Einzeleinspritzpumpe 11 vorhandene Stelleinrichtung 16, die zur Steuerung der in die zugeordneten Zylinder einzuspritzenden Brennstoffmenge dient, befindet sich außerhalb des Zylinder-Kurbelgehäuses. Die mit 19 bezeichnete Position der Stelleinrichtung 16 ist die sogenannte Null-Förderstellung einer Einzeleinspritzpumpe 11, während die Position 20 der Vollaststellung entspricht. Alle Stelleinrichtungen 16 der einer Zylinderreihe zugeordneten Einzeleinspritzpumpen 11 sind von einer mit einem Einspritzpumpen-Regler zusammenwirkenden Regulierdrehwelle 14 betätigbar. Für die Übertragung einer Stellbewegung von der Regulierdrehwelle 14 auf die Stelleinrichtung 16 ist für jede Einzeleinspritzpumpe 11 auf der Regulierdrehwelle 14 ein Regulierhebel 15 befestigt. Single-injection pumps 11 of a diesel engine, not shown, are fastened to the cylinder crankcase 12 and are actuated by a camshaft 18 . The adjusting device 16 present on each of the individual injection pumps 11 working with inclined edge control, which serves to control the amount of fuel to be injected into the associated cylinder, is located outside the cylinder crankcase. The position of the adjusting device 16 , designated 19 , is the so-called zero delivery position of a single injection pump 11 , while the position 20 corresponds to the full load position. All actuating devices 16 of the individual injection pumps 11 assigned to a row of cylinders can be actuated by a regulating rotary shaft 14 which interacts with an injection pump controller. For the transmission of an actuating movement from the regulating rotary shaft 14 to the actuating device 16 , a regulating lever 15 is fastened on the regulating rotary shaft 14 for each individual injection pump 11 .

Die Regulierdrehwelle 14 ist in verdeckter Bauweise innerhalb des Zylinder-Kurbelgehäuses 12 gelagert. Damit die auf der Regulierdrehwelle 14 befestigten Regulierhebel 15 mit der jeweils zugeordneten Stelleinrichtung 16 verbindbar sind, ist neben jeder Einzeleinspritzpumpe 11 eine Öffnung 13 im Zylinder- Kurbelgehäuse 12 ausgebildet.The regulating rotary shaft 14 is mounted in a concealed design within the cylinder crankcase 12 . So that the regulating levers 15 fastened on the regulating rotary shaft 14 can be connected to the respectively assigned actuating device 16 , an opening 13 is formed in the cylinder crankcase 12 in addition to each individual injection pump 11 .

Die Öffnung 13 dient auch zur Montage der Regulierhebel 15 beim Einbau der Regulierdrehwelle 14 ins Zylinder-Kurbelgehäuse 12.The opening 13 also serves to mount the regulating lever 15 when the regulating rotary shaft 14 is installed in the cylinder crankcase 12 .

Zum Abschluß der Montage der Einzeleinspritzpumpen 11 und der Regulierdrehwelle 14 mit den Regulierhebeln 15 wird die Stelleinrichtung 16 und die Öffnung 13 bei jeder Einzeleinspritzpumpe 11 durch eine Haube 17 schützend überdeckt. Die mit Schrauben befestigten Hauben 17 sind bei Montage und Wartungsarbeiten mit wenigen Handgriffen zu entfernen, so daß die Stelleinrichtungen 16 doch leicht zugänglich bleiben.At the end of the assembly of the individual injection pumps 11 and the regulating rotary shaft 14 with the regulating levers 15 , the actuating device 16 and the opening 13 in each individual injection pump 11 are covered by a hood 17 in a protective manner. The hoods 17 fastened with screws can be removed in a few simple steps during assembly and maintenance work, so that the actuating devices 16 remain easily accessible.
