Description

Die Erfindung bezieht sich auf eine elektrisch angetriebene Dieselkraftstoff-Förderpumpe zur Anordnung innerhalb eines Kraftstofftanks, welche im Inneren mit vom Pumpenrad der Dieselkraftstoff-Förderpumpe geförderten Kraftstoff zu fluten ist und zum Anschluß an ein elektrisches Netz eine nach oben gerichtete Steckerhülse hat. Solche Dieselkraftstoff-Förderpumpen sind derzeit allgemein bekannt und gebräuchlich.The invention relates to an electrically driven diesel fuel delivery pump for arrangement within a fuel tank, which is to be flooded inside with fuel delivered by the pump wheel of the diesel fuel delivery pump and has an upwardly directed plug sleeve for connection to an electrical network. Such diesel fuel feed pumps are currently generally known and used.

Werden Kraftstofftanks weitgehend leergefahren, dann besteht im Bereich der elektrischen Kontaktelemente innerhalb der Steckerverbindung durch Auftreten von zündfähigen Luft-Kraftstoffgemischen Explosionsgefahr. Das gilt vor allem während des Winterbetriebs, weil dem Dieselkraftstoff dann Normalkraftstoff zugemisch wird, durch den sich die Zündfähigkeit stark erhöht.If fuel tanks are largely emptied, there is a risk of explosion in the area of the electrical contact elements within the plug connection due to the occurrence of ignitable air-fuel mixtures. This is especially true during winter operation because normal fuel is then mixed into the diesel fuel, which greatly increases the ignitability.

Um eine solche Explosionsgefahr auszuschließen, hat man bei der aus der US-A-2 394 860 bekannten Förderpumpe statt einer leicht zu handhabenden Steckverbindung eine Verbindung vorgesehen, bei der das Kontaktelement des Anschlußkabels durch einen Schraubstopfen gegen das federbelastete Kontaktelement des Motorkabelsgepreßt wird. Außerdem ist durch Dichtungsstopfen dafür gesorgt, daß der eigentliche Kontaktbereich gegen den Zutritt von Kraftstoff abgedichtet ist. Diese bekannte Verbindung ist in jeder Hinsicht wesentlich aufwendiger als eine Steckverbindung.To rule out such a risk of explosion, a connection has been provided in the feed pump known from US-A-2 394 860 instead of an easy-to-use plug connection, in which the contact element of the connecting cable is pressed against the spring-loaded contact element of the motor cable by a screw plug. In addition, sealing plugs ensure that the actual contact area is sealed against the ingress of fuel. This known connection is much more complex than a plug connection in every respect.

Um den Zutritt von Luft zur Steckerverbindung zu verhindern, könnte man an ein Vergießen der Steckerhülse denken, was jedoch den Nachteil hätte, daß ein Auswechseln der Dieselkraftstoff-Förderpumpe erschwert würde. Eine andere Möglichkeit der Vermeidung einer Explosionsgefahr bestünde darin, den Steckeranschluß statt in einer Steckerhülse der Dieselkraftstoff-Förderpumpe außerhalb des Kraftstofftanks vorzusehen, was jedoch aus Kostengründen meist nicht infrage kommt.In order to prevent air from entering the plug connection, one could think of potting the plug sleeve, but this would have the disadvantage that it would be difficult to replace the diesel fuel feed pump. Another possibility of avoiding an explosion risk would be to provide the plug connection outside of the fuel tank instead of in a plug sleeve of the diesel fuel delivery pump, but this is usually out of the question for reasons of cost.

Der Erfindung liegt die Aufgabe zugrunde, auf möglichst einfache Weise bei Dieselkraftstoff-Förderpumpen der eingangs genannten Art die Explosionsgefahr im Bereich ihrer Steckerhülse auszuschließen.The invention has for its object to rule out the risk of explosion in the region of its connector sleeve in the simplest possible manner in diesel fuel delivery pumps of the type mentioned.

Diese Aufgabe wird auf überraschend einfache Weise dadurch gelöst, daß die Steckerhülse als nur nach oben hin offene Flüssigkeitskammer ausgebildet ist, die mit Dieselkraftstoff geflutet ist, und daß der Dieselkraftstoff in der Flüssigkeitskammer alle Hohlräume um die kontaktierenden Elemente ausfüllt.This object is achieved in a surprisingly simple manner in that the connector sleeve is designed as a liquid chamber which is only open at the top and which is flooded with diesel fuel, and in that the diesel fuel in the liquid chamber fills all cavities around the contacting elements.

Durch eine solche Flüssigkeitskammer wird mit sehr geringem Aufwand erreicht, daß die Steckerhülse stets auch dann mit Dieselkraftstoff geflutet bleibt, wenn der Kraftstofftank leergefahren wird. Dadurch kann keine Luft in den Bereich der kontaktierenden Elemente gelangen, so daß das Entstehen eines zündfähigen Gemisches ausgeschlossen ist. Trotz dieser zuverlässigen Luftabschirmung wird durch die erfindungsgemäße Ausbildung der Dieselkraftstoff-Förderpumpe die einfache Funktion des Steckanschlusses nicht beeinträchtigt. Der Stecker kann ohne jede Behinderung in die Steckerhülse geschoben oder aus ihr herausgezogen werden.With such a liquid chamber it is achieved with very little effort that the connector sleeve always remains flooded with diesel fuel even when the fuel tank is run empty. As a result, no air can get into the area of the contacting elements, so that the formation of an ignitable mixture is excluded. Despite this reliable air shielding, the simple function of the plug connection is not impaired by the inventive design of the diesel fuel feed pump. The plug can be pushed into or pulled out of the plug sleeve without any hindrance.

Aus der Flüssigkeitskammer beispielsweise infolge von Erschütterungen während des Fahrbetriebs nach oben hin austretender Dieselkraftstoff wird immer wieder ergänzt, so daß der Luftabschluß erhalten bleibt, wenn die Flüssigkeitskammer an ihrer Oberseite einen von dem Pumpenrad gespeisten Kraftstoffzufluß hat.Diesel fuel escaping upward out of the liquid chamber, for example as a result of vibrations during driving, is continuously replenished, so that the air seal is maintained when the liquid chamber has a fuel inflow fed by the pump wheel on its upper side.

Besonders einfach ist der Zufluß mit Dieselkraftstoff zu versorgen, wenn gemäß einer anderen Ausgestaltung der Erfindung der Kraftstoffzufluß über eine Bohrung im oberen Lagerschild mit dem Inneren der Dieselkraftstoff-Förderpumpe in Verbindung steht.The inflow is particularly easy to supply with diesel fuel if, according to another embodiment of the invention, the fuel inflow is connected to the interior of the diesel fuel delivery pump via a hole in the upper end shield.

Die Bohrung kann sehr kurz sein, wenn sie im Lagerschildgehäuse zum Lager des Rotors des Pumpenmotors führt.The bore can be very short if it leads to the bearing of the rotor of the pump motor in the end shield housing.

Zur weiteren Vereinfachung des Aufbaus der Dieselkraftstoff-Förderpumpe trägt es bei, wenn oberhalb des Kraftstoffzuflusses fluchtend zur Bohrung des Lagerschildes eine den aus der Bohrung nach oben spritzenden Flüssigkeitsstrahl zur Flüssigkeitskammer hin umlenkende Prallfläche vorgesehen ist. Bei einer solchen Ausgestaltung ist kein bis zum oberen Ende der Flüssigkeitskammer reichender Strömungskanal erforderlich.To further simplify the structure of the diesel fuel delivery pump, it is provided if, above the fuel inflow, in alignment with the bore of the end shield, a baffle is provided which deflects the liquid jet spraying upwards out of the bore toward the liquid chamber. In such an embodiment, no flow channel reaching to the upper end of the liquid chamber is required.

Die Prallfläche kann am Ende einer nach oben gerichteten Abschirmwand des Lagerschildes vorgesehen werden. Das Lagerschild kann, abgesehen von der erforderlichen Bohrung, unverändert bleiben, wenn die Prallfläche durch einen nach außen gerichteten, dachartigen Vorsprung des Gehäuses des Steckes gebildet ist.The impact surface can be provided at the end of an upward shielding wall of the end shield. The end shield, apart from the required hole, can remain unchanged if the impact surface is formed by an outwardly directed, roof-like projection of the housing of the plug.

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips sind zwei davon schematisch in der Zeichnung dargestellt und werden nachfolgend beschrieben. Die Zeichnung zeigt in

The invention allows numerous embodiments. To further clarify its basic principle, two of them are shown schematically in the drawing and are described below. The drawing shows in
Fig. 1
2 shows a longitudinal section through a diesel fuel delivery pump designed according to the invention,
Fig. 2
a greatly enlarged sectional view of an upper area of a second embodiment of a diesel fuel delivery pump designed according to the invention.

Die in Figur 1 als Ganzes dargestellte Dieselkraftstoff-Förderpumpe hat ein Gehäuse 1, welches an beiden Stirnseiten jeweils durch einen Lagerschild 2, 3 abgeschlossen ist. Der untere Lagerschild 3 ist mit einem Kraftstoffeinlaß 4 und der obere Lagerschild 2 mit einem Kraftstoffauslaß 5 ausgestattet. Im Inneren des Gehäuses 1 sind, auf einer gemeinsamen Welle 6 gelagert, ein Pumpenrad 7 zur Förderung des Dieselkraftstoffes und ein Rotor 8 eines elektrischen Pumpenmotors 9 angeordnet. Die Welle 6 ist in beiden Lagerschilden 2, 3 jeweils in einem Lager 10, 11 gelagert.The diesel fuel feed pump shown as a whole in FIG. 1 has a housing 1, which is closed at both ends by a bearing plate 2, 3. The lower end plate 3 is equipped with a fuel inlet 4 and the upper end plate 2 with a fuel outlet 5. A pump wheel 7 for conveying the diesel fuel and a rotor 8 of an electric pump motor 9 are arranged in the interior of the housing 1, mounted on a common shaft 6. The shaft 6 is supported in a bearing 10, 11 in each of the two end shields 2, 3.

Die Stromversorgung des Pumpenmotors 9 erfolgt über elektrische Leiter 12, die in eine Steckerhülse 13 am oberen Lagerschild 2 hochgeführt sind, in die von oben her ein Stecker 14 eingesetzt ist.The pump motor 9 is supplied with power via electrical conductors 12, which are led up into a plug sleeve 13 on the upper end plate 2, into which a plug 14 is inserted from above.

Wichtig für die Erfindung ist, daß die Steckerhülse 13 als nur nach oben hin offene Flüssigkeitskammer 15 ausgebildet ist. Zur Versorgung dieser Flüssigkeitskammer 15 hat diese an ihrer Oberseite einen Kraftstoffzufluß 16. Zur Versorgung dieses Kraftstoffzuflusses 16 mit Dieselkraftstoff ist im oberen Lagerschild 2 eine Bohrung 17 vorgesehen, die zur Stirnseite des Lagers 17 der Welle 6 führt. Aus dieser Bohrung 17 spritzt beim Arbeiten der Dieselkraftstoff-Förderpumpe Dieselkraftstoff nach oben durch einen Strahlraum 18 gegen eine Prallfläche 19, welche bei dieser Ausführungsform durch einen Vorsprung 20 am Gehäuse des Steckers 14 gebildet ist. Die Prallfläche 19 lenkt den Flüssigkeitsstrahl zur Flüssigkeitskammer 15 hin um. Der Strahlraum 18 ist nach außen hin durch eine Abschirmwand 21 des Lagerschildes 2 abgeschlossen.It is important for the invention that the plug sleeve 13 is designed as a liquid chamber 15 which is only open at the top. To supply this liquid chamber 15, it has a fuel inflow 16 on its upper side. To supply this fuel inflow 16 with diesel fuel, a bore 17 is provided in the upper end shield 2, which leads to the end face of the bearing 17 of the shaft 6. When the diesel fuel delivery pump is working, diesel fuel splashes out of this bore 17 upwards through a blasting chamber 18 against an impact surface 19, which in this embodiment is provided by a Projection 20 is formed on the housing of the plug 14. The baffle 19 deflects the liquid jet towards the liquid chamber 15. The blasting chamber 18 is closed to the outside by a shielding wall 21 of the end shield 2.

Bei der Ausführungsform gemäß Figur 2 reicht die Abschirmwand 21 weiter nach oben als bei der zuvor beschriebenen Ausführungsform. An ihrem oberen Ende ist die Prallfläche 19 vorgesehen. Sie ist so schräg ausgerichtet, daß der aus der Bohrung 17 austretende Flüssigkeitsstrahl zur Flüssigkeitskammer 15 hin umgelenkt wird. Wegen des gegenüber Figur 1 wesentlich größeren Maßstabes läßt Figur 2 deutlicher erkennen, wie der Stecker 14 den Leiter 12 kontaktiert und daß alle Hohlräume im Stecker 14 mit Dieselkraftstoff ausgefüllt sind.In the embodiment according to FIG. 2, the shielding wall 21 extends further upwards than in the previously described embodiment. The baffle surface 19 is provided at its upper end. It is oriented obliquely so that the liquid jet emerging from the bore 17 is deflected towards the liquid chamber 15. Because of the much larger scale compared to FIG. 1, FIG. 2 shows more clearly how the plug 14 contacts the conductor 12 and that all cavities in the plug 14 are filled with diesel fuel.
