Definitions
- the invention relates to a delivery unit for conveying fuel from a fuel tank to an internal combustion engine of a motor vehicle with a fuel pump, which is arranged in a surge chamber and having a metal housing and with a fuel filter, which is arranged downstream of the fuel pump ( EP-A-0 754 852 ).
- the present invention is therefore based on the object to provide a conveyor unit with little effort in the production.
- the object is achieved in that the housing of the fuel filter is electrically connected to the housing of the fuel pump.
- electrostatic charges of the fuel filter can be passed in a particularly simple manner to the fuel pump, which is grounded via its power supply. Additional safety devices for discharging electrostatic charges may be omitted.
- the dissipation of electrostatic charges can be accomplished in a simple manner with a metal filter housing.
- the housing of the fuel filter consists of an electrically conductive plastic.
- a plastic housing has the advantage over a metal housing that it can be easily produced by means of injection molding, resulting in much larger design options. As a result, such a filter housing can be adapted to the most diverse conditions of use.
- the electrical conductivity of the housing of the fuel filter is achieved in a simple manner by admixtures of carbon in the form of carbon black or nanotubes or metal particles.
- the arrangement of the fuel pump in the swirl pot is usually via a pump holder.
- This must therefore be designed so that an electrically conductive connection is made possible from the filter housing to the pump housing.
- the pump holder is also made of an electrically conductive plastic, which is integrally formed on the filter housing. Such a component can be produced particularly easily by means of injection molding.
- the housing of the fuel filter is connected to the holder for the fuel pump via an integrally formed web.
- the variation possibilities arise due to the arrangement of the web with respect to the circumference and the height of the filter housing and the width of the web, which determines the distance of the pump holder to the filter housing.
- the cost of producing such a component remains almost the same due to this design.
- connection of the filter housing to the housing of the fuel pump can be produced by connecting the housing of the fuel filter to the fuel pump via the inlet connection. Since the fuel pumped by the fuel pump must anyway be supplied to the fuel filter, the inlet port is designed so that it is connectable to the outlet port of the fuel pump, preferably by plugging. The outlet in the connection piece of the fuel pump must also consist of an electrically conductive material.
- FIG. 1 shows a fuel tank 1 of a motor vehicle not shown with a conveyor unit 2, which is inserted through an opening 3 in the fuel tank 1. After installation, the opening 3 is closed with a flange 4.
- the delivery unit 2 consists of a prestressed against the bottom of the fuel tank 1 swirl pot 5.
- a fuel pump 6 is arranged, which sucks fuel from the swirl pot 5 and promotes via an outlet 7.
- a fuel filter 8 is arranged, which, viewed fluidly, is arranged downstream of the fuel pump 6, so that the fuel pumped by the fuel pump 6 reaches the fuel filter 8 via an inlet port 9.
- the filtered fuel is then via a flow line 10 through the flange 4 to a not shown Internal combustion engine of the motor vehicle.
- the housing 11 of the fuel filter 8 has a one-piece molded web 12, which merges into a pump holder 13.
- the fuel pump 6 is mounted in the region of its metallic housing 14.
- the filter housing 11 is made of polyoxymethylene, which is electrically conductive by the addition of carbon black. In the fuel filter 8 resulting electrostatic charges can be transmitted through the filter housing 11, the web 14 and the pump holder 13 to the housing 14 of the fuel pump 6, from where they are safely discharged via the power supply, not shown.
- FIG. 2 shows the filter housing 11 with the outlet port 10 and the inlet port 9.
- the fuel filter is not shown in this view.
- To the filter housing 11 of the pump holder 13 is integrally formed by injection molding, so that both components form a unit.
- FIG. 3 shows the filter housing 11, the lower end is closed with a lid 15. About molded on the lid 15 locking hooks, the fuel filter 8 can be fixed in the swirl pot.
- the pump holder 13 also has latching hooks 17, via which the pump holder is additionally connectable to the swirl pot.
- longitudinal webs 18 and retaining springs 19 are formed for receiving and supporting the fuel pump 6, not shown.
- the filter housing 11 further has an elongated inlet port 9 with a receptacle 20 which is designed such that it can be plugged onto the outlet port 7 of the fuel pump 6.

Abstract
Description
Gegenstand der Erfindung ist eine Fördereinheit zum Fördern von Kraftstoff aus einem Kraftstoffbehälter zu einer Brennkraftmaschine eines Kraftfahrzeugs mit einer Kraftstoffpumpe, welche in einem Schwalltopf angeordnet ist und ein aus Metall bestehendes Gehäuse aufweist und mit einem Kraftstofffilter, welcher stromabwärts der Kraftstoffpumpe angeordnet ist (
Derartige Fördereinheiten sind seit langem bekannt und somit Stand der Technik. Dazu ist es bekannt, den Kraftstofffilter Schwalltopf anzuordnen. Aufgrund vorgegebener Sicherheitsbestimmungen müssen Bauteile, welche mit strömenden Flüssigkeiten in Kontakt kommen, gegen elektrostatische Aufladungen abgesichert sein. Dadurch steigt der Aufwand für die Herstellung der Fördereinheit.Such conveyor units have long been known and thus state of the art. For this purpose it is known to arrange the fuel filter swirl pot. Due to specified safety regulations, components that come into contact with flowing liquids must be protected against electrostatic charges. This increases the effort for the production of the conveyor unit.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Fördereinheit mit geringem Aufwand in der Herstellung vorzusehen.The present invention is therefore based on the object to provide a conveyor unit with little effort in the production.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass das Gehäuse des Kraftstofffilters mit dem Gehäuse der Kraftstoffpumpe elektrisch leitend verbunden ist.According to the invention the object is achieved in that the housing of the fuel filter is electrically connected to the housing of the fuel pump.
Durch die elektrisch leitende Verbindung der beiden Gehäuse können elektrostatische Aufladungen des Kraftstofffilters in besonders einfacher Weise zur Kraftstoffpumpe geleitet werden, die über ihre Stromversorgung geerdet ist. Zusätzliche Sicherheitsvorrichtungen für die Ableitung elektrostatische Aufladungen können entfallen.Due to the electrically conductive connection of the two housings electrostatic charges of the fuel filter can be passed in a particularly simple manner to the fuel pump, which is grounded via its power supply. Additional safety devices for discharging electrostatic charges may be omitted.
Die Ableitung elektrostatischer Aufladungen lässt sich in einfacher Weise mit einem Filtergehäuse aus Metall bewerkstelligen.The dissipation of electrostatic charges can be accomplished in a simple manner with a metal filter housing.
Erfindungsgemäß besteht das Gehäuse des Kraftstofffilters aus einem elektrisch leitfähigen Kunststoff. Ein Kunststoffgehäuse hat gegenüber einem Metallgehäuse den Vorteil, dass es sich einfach mittels Spritzgießen herstellen lässt, wodurch sich wesentlich größere Gestaltungsmöglichkeiten ergeben. Dadurch kann ein derartiges Filtergehäuse an die verschiedensten Einsatzbedingungen angepasst werden.According to the invention, the housing of the fuel filter consists of an electrically conductive plastic. A plastic housing has the advantage over a metal housing that it can be easily produced by means of injection molding, resulting in much larger design options. As a result, such a filter housing can be adapted to the most diverse conditions of use.
Die elektrische Leitfähigkeit des Gehäuses des Kraftstofffilters wird in einfacher Weise durch Beimischungen von Kohlenstoff in Form von Ruß oder Nanotubes oder von Metallpartikeln erreicht.The electrical conductivity of the housing of the fuel filter is achieved in a simple manner by admixtures of carbon in the form of carbon black or nanotubes or metal particles.
Die Anordnung der Kraftstoffpumpe im Schwalltopf erfolgt in der Regel über einen Pumpenhalter. Dieser muß demzufolge so ausgebildet sein, dass eine elektrisch leitende Verbindung vom Filtergehäuse zum Pumpengehäuse ermöglicht wird. Gemäß einer vorteilhaften Ausgestaltung besteht der Pumpenhalter ebenfalls aus einem elektrisch leitfähigen Kunststoff, der an dem Filtergehäuse einteilig angeformt ist. Ein derartiges Bauteil lässt sich besonders einfach mittels Spritzgießen herstellen.The arrangement of the fuel pump in the swirl pot is usually via a pump holder. This must therefore be designed so that an electrically conductive connection is made possible from the filter housing to the pump housing. According to an advantageous embodiment of the pump holder is also made of an electrically conductive plastic, which is integrally formed on the filter housing. Such a component can be produced particularly easily by means of injection molding.
Um die Anordnung vom Kraftstoffpumpe und Kraftstofffilter im Schwalltopf variabel an verschiedene Einsatzbedingungen anpassen zu können, ist das Gehäuse des Kraftstofffilters mit dem Halter für die Kraftstoffpumpe über einen integral angeformten Steg verbunden. Die Variationsmöglichkeiten ergeben sich aufgrund der Anordnung des Stegs bezüglich des Umfangs und der Höhe des Filtergehäuses sowie der Breite des Steges, welcher den Abstand des Pumpenhalters zum Filtergehäuse bestimmt. Der Aufwand für die Herstellung eines derartigen Bauteils bleibt durch diese Ausgestaltung nahezu gleich.In order to be able to variably adapt the arrangement of the fuel pump and fuel filter in the swirl pot to different operating conditions, the housing of the fuel filter is connected to the holder for the fuel pump via an integrally formed web. The variation possibilities arise due to the arrangement of the web with respect to the circumference and the height of the filter housing and the width of the web, which determines the distance of the pump holder to the filter housing. The cost of producing such a component remains almost the same due to this design.
In einer nicht erfindungsgemäßens anderen Ausgestaltung lässt sich die Verbindung des Filtergehäuses mit dem Gehäuse der Kraftstoffpumpe dadurch herstellen, dass das Gehäuse des Kraftstofffilters über den Einlassstutzen mit der Kraftstoffpumpe verbunden ist. Da der von der Kraftstoffpumpe geförderte Kraftstoff ohnehin dem Kraftstofffilter zugeführt werden muß, ist der Einlassstutzen so ausgestaltet, dass er mit dem Auslassstutzen der Kraftstoffpumpe verbindbar, vorzugsweise durch Aufstecken, ist. Der Auslassstutzen im Anschlussstück der Kraftstoffpumpe muß dabei ebenfalls aus einem elektrisch leitfähigen Material bestehen.In another embodiment not according to the invention, the connection of the filter housing to the housing of the fuel pump can be produced by connecting the housing of the fuel filter to the fuel pump via the inlet connection. Since the fuel pumped by the fuel pump must anyway be supplied to the fuel filter, the inlet port is designed so that it is connectable to the outlet port of the fuel pump, preferably by plugging. The outlet in the connection piece of the fuel pump must also consist of an electrically conductive material.
