Description
Die vorliegende Erfindung betrifft einen Flansch eines Kraftstoff-Fördermoduls sowie ein Kraftstoff-Fördermodul. Derartige Flansche bzw. Kraftstoff-Fördermodule werden am Tank insbesondere von Kraftfahrzeugen eingesetzt, um den Tank mit der Kraftstoffzuführleitung eines Motors zu verbinden.The present invention relates to a flange of a fuel delivery module as well as a fuel delivery module. Such flanges or fuel delivery modules are used on tanks in particular by motor vehicles, to connect the tank to the fuel supply line of an engine.
Ein bekannter derartiger Flansch umfaßt einen Druckregler zum Regeln des Drucks in der Kraftstoffzufuhrleitung. Bei Überschreitung des einzuregelnden Drucks läßt der Druckregler Kraftstoff durch eine Drosselstelle entweichen. Aufgrund der hohen Strömungsgeschwindigkeit des Kraftstoffs in der Drosselstelle des Druckreglers bildet sich eine starke Ladungstrennung aus, was die Gefahr einer sehr starken elektrostatischen Aufladung des Druckreglers und seiner Umgebung mit sich bringt.A known such flange comprises a pressure regulator for regulating the Pressure in the fuel supply line. If the to be regulated is exceeded The pressure regulator allows fuel to escape through a throttle point. Due to the high flow rate of the fuel in the The throttling point of the pressure regulator forms a strong charge separation, what the danger of a very strong electrostatic charge of the pressure regulator and its surroundings.
Um diese Gefahr zu verringern ist bei dem bekannten Flansch vorgesehen, daß eine am Gehäuse des Druckreglers befestigte elektrische Leitung diesen leitend mit einer Versorgungsleitung einer Kraftstoffpumpe des Kraftstoff-Fördermoduls verbindet, um so das Gehäuse des Druckreglers auf einem definierten Potential zu halten.In order to reduce this risk, the known flange provides that an electrical line attached to the housing of the pressure regulator conductive with a supply line of a fuel pump of the fuel delivery module connects, so the housing of the pressure regulator on one keep defined potential.
Das Anbringen der Leitung zwischen dem Druckregler und der Versorgungsleitung ist arbeitsaufwendig, und es ist nicht auszuschließen, daß im Laufe des Betriebs des Fahrzeugs der elektrische Kontakt zwischen dem Druckregler und der Versorgungsleitung verlorengeht, sei es aufgrund von Kabelbruch, unfächmännischer Wartung oder anderem, so daß sich unbemerkt dennoch elektrostatische Aufladungen bilden können.Attaching the line between the pressure regulator and the supply line is labor intensive, and it cannot be excluded that in the course the operation of the vehicle the electrical contact between the pressure regulator and the supply line is lost, be it due to a cable break, improper maintenance or other, so that it goes unnoticed can still form electrostatic charges.
Aus US-A-5,642,718 ist ein Kraftstoff-Fördermodul mit einem Flansch, einer am Flansch befestigten Pumpe, einem Druckregler und einem Filter bekannt. Ein aus leitfähigem Kunststoff bestehendes Gehäuse der Pumpe ist gegen die Energiequelle der Pumpe isoliert, der Flansch ist aus nichtleitendem Kunstharz.From US-A-5,642,718 is a fuel delivery module with a flange, one known pump attached to the flange, a pressure regulator and a filter. A housing made of conductive plastic of the pump is against The pump's energy source is insulated, the flange is made of non-conductive synthetic resin.
Durch die vorliegende Erfindung, wie in Anspruch 1 bzw. Anspruch 11
definiert, wird ein Flansch eines Kraftstoff-Fördermoduls bzw. ein Kraftstoff-Fördermodul
geschaffen, welcher bzw. welches bei einfachem Aufbau hohe
Betriebssicherheit aufweist.By the present invention as in claim 1 and
Vorteilhafte Weiterentwicklungen des Flansches bzw. des Kraftstoff-Fördermoduls sind in den Ansprüchen 2 bis 10 und 12 definiert.Advantageous further developments of the flange or the fuel delivery module are defined in claims 2 to 10 and 12.
Die leitende Verbindung des Druckreglers mit dem Anschluß über das schwach leitende Material gemäß der Erfindung legt das Potential des Druckreglers allein durch dessen Anbringen am Flansch fest, ohne daß hierzu weitere Montageschritte und -teile erforderlich wären. Es ergibt sich somit ein Kostenvorteil durch Einsparung von Arbeitszeit und Teilen sowie ein Qualitätsvorteil, da die als Teil des Flansches ausgebildete leitende Verbindung zwischen dem Druckregler und dem Anschluß sich nicht z.B. durch Kabelbruch oder Lösen eines Steckkontakts öffnen kann. The conductive connection of the pressure regulator with the connection via the weakly conductive material according to the invention sets the potential of Pressure regulator by simply attaching it to the flange, without this would require further assembly steps and parts. It follows thus a cost advantage by saving working hours and parts as well a quality advantage because the conductive part of the flange Connection between the pressure regulator and the connection is not e.g. can open by breaking the cable or loosening a plug contact.
Um im Falle eines in einer Rückführleitung zum Tank angeordneten Druckreglers durch alleinige Erdung des Druckreglers noch nicht abgeleitete elektrostatische Ladungen zuverlässig zu erfassen, kann zusätzlich vorgesehen werden, daß auch die Rückführleitung selber mit dem Anschluß leitend verbunden ist.In the case of a pressure regulator arranged in a return line to the tank not yet derived by simply grounding the pressure regulator Reliable detection of electrostatic charges can also be provided be that the return line itself is conductively connected to the connection is.
Dazu ist zweckmäßigerweise der Flansch einstückig aus einem schwach elektrisch leitenden Kunststoff gebildet. Dabei kann es sich um ein im wesentlichen beliebiges, gegen Kontakt mit Kraftstoff beständiges Kunstharz handeln, das durch Einbringung von Graphit- oder Metallteilchen leitfähig gemacht ist. Die Leitfähigkeit des Kunststoffs ist zweckmäßigerweise auf Oberflächenwiderstandswerte zwischen 103 Ohm und 109 Ohm eingestellt, um einerseits die elektrostatischen Ladungen zuverlässig abzuleiten, andererseits die mechanischen Eigenschaften des eine Matrix bildenden Kunstharzes durch die eingebrachten leitfähigen Teilchen nicht zu stark zu verändern.For this purpose, the flange is expediently formed in one piece from a weakly electrically conductive plastic. This can be an essentially any synthetic resin that is resistant to contact with fuel and is made conductive by introducing graphite or metal particles. The conductivity of the plastic is expediently set to surface resistance values between 10 3 ohms and 10 9 ohms, in order on the one hand to reliably discharge the electrostatic charges and on the other hand not to change the mechanical properties of the synthetic resin forming a matrix too much by the introduced conductive particles.
Der Anschluß ist bevorzugtermaßen eine elektrische Durchführung.The connection is preferably an electrical feedthrough.
Der elektrische Kontakt zwischen der Durchführung und dem Material des Flansches wird vorteilhaftetweise dadurch hergestellt, daß ein Leiter der elektrischen Durchführung von dem schwach elektrisch leitenden Material ohne Isolation umgeben ist. Vorzugsweise wird bei der Herstellung des Flansches durch Spritzgießen die elektrische Durchführung in das schwach elektrisch leitende Material eingebettet.The electrical contact between the bushing and the material of the Flange is advantageously manufactured in that a conductor of electrical implementation of the weakly electrically conductive material is surrounded without isolation. Preferably in the manufacture of the Flange by injection molding the electrical feedthrough into the weak electrically conductive material embedded.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels mit Bezug auf die beigefügte Figur. Further features and advantages of the invention result from the following Description of an embodiment with reference to the accompanying Figure.
Die einzige Figur zeigt ein Kraftstoff-Fördermodul mit einem Flansch gemäß der Erfindung im Querschnitt.The single figure shows a fuel delivery module with a flange according to of the invention in cross section.
Die Figur zeigt ein Kraftstoff-Fördermodul zum Einbau in einem Tank eines
Kraftfahrzeugs. Das Modul umfaßt eine Kraftstoffpumpe 1, die über einen
Filtervorsatz 3 Kraftstoff aus dem Tank ansaugt und über einen Auslaßstutzen
5 in eine Filterkammer 7 preßt, die sich in Form eines Hohlzylinders
um die Pumpe 1 herum erstreckt. Ein Filterkörper 9 ist in der
Kammer 7 angeordnet und an seinen Stirnseiten durch O-Ringe 11 abgedichtet.
Eine Schlauchleitung 13 verbindet den Auslaß der Filterkammer 7 mit
einem Anschlußstutzen 15 an der Innenseite eines Flansches 17. Ein
Kraftstoffdurchgang 19 erstreckt sich vom Stutzen 15 in der Figur zunächst
vertikal durch den Flansch 17 hindurch und horizontal nach rechts zu einem
Auslaßstutzen 21, der zur Anbringung einer zum Motor führenden Kraftstoffzufuhrleitung
vorgesehen ist. Eine in der Figur nach links verlaufende
Rückführleitung 23 verbindet den Kraftstoffdurchgang 19 mit einem Druckregler
25, der in einer Aussparung an der Innenseite des Flansches 17
befestigt ist. Der Druckregler 25 enthält in einem Gehäuse eine Membran
27, die sein Inneres in eine Kraftstoffkammer 31 und eine Gegendruckkammer
29 unterteilt. Die Gegendruckkammer 29 enthält eine Druckspiralfeder
33, die die Membran 27 dicht gegen einen Reglersitz 35 preßt. Erst wenn
der Druck in der Kraftstoffkammer 31 einen Mindestwert überschreitet, rückt
die Membran 27 geringfügig vom Reglersitz 35 ab, so daß durch die sich
öffnende Drosselstelle Kraftstoff in einen stromabwärtigen Abschnitt der
Rückführleitung 23 und von dort aus zurück in den Tank strömen kann.The figure shows a fuel delivery module for installation in a tank
Motor vehicle. The module comprises a fuel pump 1, which has a
Filter attachment 3 draws fuel from the tank and through an outlet connection
5 presses into a filter chamber 7, which is in the form of a hollow cylinder
extends around the pump 1. A filter body 9 is in the

Eine elektrische Durchführung umfaßt einen Steckverbinder 37 mit zwei
Messerkontakten 39 und zwei daran angeschlossene, durch den Flansch 17
geführte Drähte 41. Die Durchführung bildet einen Anschluß an externe
Potentiale einer Batterie. Der Steckverbinder 37 ist einstückig an den
Flansch 17 angeformt, und die Messerkontakte 39 sind zu ihrer Verankerung
mit dem Material des Flansches umspritzt. Die Drähte 41 sind mit der
Pumpe 1 verbunden, um diese mit Energie zu versorgen.An electrical feedthrough comprises a
Der Flansch 17 einschließlich des Steckverbinders 37 besteht aus einem
schwach elektrisch leitenden Kunststoffmaterial, wie etwa einer Kunstharzmatrix
mit eingebetteten leitfähigen Metall- oder Graphitteilchen. Die metallischen
Messerkontakte 39 stehen mit diesem Material ohne dazwischenliegende
Isolierung in direktem Kontakt. Auf diese Weise sind sie mit dem
Gehäuse des Druckreglers 25 sowie der gesamten Innenfläche der Rückführleitung
23 leitend verbunden. Eine Ansammlung von elektrostatischen
Ladungen ist so auf der ganzen Länge der Rückführleitung 23 zuverlässig
ausgeschlossen.The
Es ist ohne weiteres möglich, von den zwei Messerkontakten 39 einen gegen
den Flansch 17 elektrisch zu isolieren. Dies ist aber nicht unbedingt
erforderlich. Um die geringen elektrostatischen Ladungen, die sich in der
Rückführleitung 23 und am Druckregler bilden, zuverlässig abzuleiten, ist
eine sehr geringe Leitfähigkeit des Flanschmaterials ausreichend. Es ist
deshalb kein Problem, die Leitfähigkeit so einzustellen, daß die ausreichende
Ableitung der elektrostatischen Ladungen sicher gewährleistet ist, daß aber
dennoch Leckströme zwischen den Messerkontakten 39 durch das Flanschmaterial
so gering gehalten werden, daß sie technisch nicht ins Gewicht fallen.It is readily possible to counter one of the two
Als Anschluß an ein externes Potential kann anstelle des oben beschriebenen Steckverbinders eine beliebige andere elektrische Verbindung, etwa eine Lüsterklemme, eine Schraube-Öse-Verbindung oder dergleichen verwendet werden. Der Anschluß kann auch durch eine leitfähige Schraube zur Befestigung des Flansches am Tank gebildet sein, soweit dieser leitfähig ist und ein definiertes elektrisches Potential hat.As a connection to an external potential, instead of the one described above Any other electrical connection, such as a connector Luster clamp, a screw-eye connection or the like is used become. The connection can also be made using a conductive screw Attachment of the flange to the tank, if it is conductive and has a defined electrical potential.
