Die Rippen (18, 19) sind quer zur längsten Erstreckung der Querschnitte der Kanäle (16, 17) angeordnet und erzeugen eine hohe Stabilität im Bereich der Kanäle (16, 17). Die Gehäuseteile (8, 9) sind aus Kunststoff gefertigt.In a fuel pump (2) operating according to the gerotor principle, ribs (18, 19) arranged in housing parts (8, 9) and designed as inlet and outlet have ribs (18, 19). The ribs (18, 19) are arranged transversely to the longest extent of the cross sections of the channels (16, 17) and produce a high stability in the region of the channels (16, 17). The housing parts (8, 9) are made of plastic.
Description
Die Erfindung betrifft eine nach dem Gerotorprinzip arbeitende Kraftstoffpumpe zur Förderung von Kraftstoff aus einem Kraftstoffbehälter eines Kraftfahrzeuges mit einem Gehäuse, mit einem zwischen zwei Gehäuseteilen gelagerten Läuferpaar, mit in dem Gehäuse angeordneten und langgestreckt gestalteten Kanälen eines Einlasses und eines Auslasses.The The invention relates to a working according to the gerotor principle fuel pump for the promotion of Fuel from a fuel tank of a motor vehicle with a housing, with one between two housing parts stored pair of runners, with in the case arranged and elongated shaped channels of an inlet and a Outlet.
Solche Kraftstoffpumpen werden insbesondere zur Förderung von Diesel-Kraftstoff in heutigen Kraftfahrzeugen häufig eingesetzt und sind aus der Praxis bekannt. Das Läuferpaar der nach dem Gerotorprinzip arbeitenden Kraftstoffpumpe weist einen Innenläufer mit einer Außenverzahnung und einen Außenläufer mit einer Innenverzahnung auf. Die Außenverzahnung hat dabei meist einen Zahn mehr als die Innenverzahnung. Der Drehpunkt des Innenläufers ist versetzt zu dem Drehpunkt des Außenläufers. Die Kanäle des Einlasses und des Auslasses sind meist in gegenüberliegenden Gehäuseteilen angeordnet. Damit wird die Kraftstoffpumpe axial durchströmt.Such Fuel pumps are used in particular to promote diesel fuel common in today's motor vehicles used and are known from practice. The runner pair the operating according to the gerotor principle fuel pump has an internal rotor an external toothing and an external rotor with an internal toothing on. The external teeth usually have one tooth more than the internal toothing. The pivot point of the inner rotor is offset to the fulcrum of the outer rotor. The channels of the inlet and the outlet are usually in opposite housing parts arranged. Thus, the fuel pump is flowed through axially.
Nachteilig bei der bekannten Kraftstoffpumpe ist, dass die langgestreckten Kanäle des Einlasses und des Auslasses die Stabilität des Gehäuses beeinträchtigen. In der Praxis behilft man sich damit, einen Versteifungsring aus Stahl zur radialen Fixierung und zwei Keramikplatten oder Metallplatten als axiale Begrenzung des Läuferpaares in den Gehäuseteilen anzuordnen. Hierdurch gestaltet sich die bekannte Kraftstoffpumpe sehr kostenintensiv.adversely in the known fuel pump is that the elongated channels the inlet and the outlet affect the stability of the housing. In practice, one makes use of it, a stiffening ring Steel for radial fixation and two ceramic plates or metal plates as axial limit of the pair of runners in the housing parts to arrange. As a result, the known fuel pump designed very expensive.
Der Erfindung liegt das Problem zugrunde, eine Kraftstoffpumpe der eingangs genannten Art so weiterzubilden, dass sie besonders einfach aufgebaut und kostengünstig zu fertigen ist.Of the Invention is based on the problem, a fuel pump of the beginning so-called type so that they are particularly simple and cost-effective to be finished.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass zumindest einer der Kanäle zumindest eine Rippe zur Versteifung des Gehäuses hat.This Problem is inventively characterized solved, that at least one of the channels has at least one rib for stiffening the housing.
Durch diese Gestaltung vermag die Rippe den Kanal zu versteifen und damit ein Durchbiegen des Gehäuses im Bereich des Kanals zu vermeiden. Hierdurch hat das Gehäuse im Bereich des Kanals eine besonders hohe Stabilität. Die hohe Stabilität ist insbesondere am Auslass von großem Vorteil, da hier hohe Kräfte senkrecht auf den den Kanal des Auslasses aufweisenden Bereich des Gehäuses wirken. Ein von den auftretenden Kräften hervorgerufenes Durchbiegen des Gehäuses im Bereich der Kanäle lässt sich hierdurch vermeiden. Damit lässt sich das Gehäuse aus einem sehr dünnwandigen und kostengünstigen Material fertigen. Die erfindungsgemäße Kraftstoffpumpe benötigt hierdurch keinen separat zu montierenden Versteifungsring, ist daher besonders einfach aufgebaut und lässt sich zudem besonders kostengünstig fertigen.By this design allows the rib to stiffen the canal and thus a bending of the housing in the area of the canal. As a result, the housing has in the area the channel a particularly high stability. The high stability is in particular at the outlet of large Advantage, since high forces perpendicular to the channel of the outlet having area of the housing Act. A bending caused by the occurring forces of the housing in the area of the channels can be avoid this. Leave it the case from a very thin-walled and cost-effective Manufacture material. The fuel pump according to the invention thus requires no separately mounted stiffening ring, is therefore particularly simple built up and leaves also very cost effective finished.
Es könnten beispielsweise mehrere Rippen die Kanäle gitterartig überdecken. Die Anzahl der Rippen lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders gering halten, wenn die zumindest eine Rippe quer zur längsten Erstreckung des Querschnitts des Kanals angeordnet ist und einander gegenüberliegende, den Kanal begrenzende Ränder des Gehäuses miteinander verbindet. Weiterhin werden hier durch die Abmessungen und damit eine Drosselwirkung der Rippen besonders gering gehalten.It could For example, several ribs cover the channels lattice-like. The number of ribs leaves according to one other advantageous embodiment of the invention particularly low hold when the at least one rib transverse to the longest extent of the cross section the channel is arranged and the opposite, the channel limiting margins of the housing connects with each other. Furthermore, here are by the dimensions and thus kept a throttling effect of the ribs particularly low.
Zur weiteren Verringerung des Montageaufwandes der erfindungsgemäßen Kraftstoffpumpe trägt es bei, wenn die Rippe einstückig mit den an die Kanäle angrenzenden Bereichen des Gehäuses gefertigt ist.to further reduction of the assembly costs of the fuel pump according to the invention contributes, when the rib is in one piece with the to the channels adjacent areas of the housing is made.
Die erfindungsgemäße Kraftstoffpumpe lässt sich besonders kostengünstig fertigen, wenn zumindest eines der Gehäuseteile aus Kunststoff gefertigt ist. Die im Vergleich zu den Keramikplatten der bekannten Kraftstoffpumpe geringe Festigkeit der aus Kunststoff gefertigten Gehäuseteile wird durch die Rippen in den Kanälen ausgeglichen.The Inventive fuel pump let yourself especially inexpensive finished, if at least one of the housing parts is made of plastic. The compared to the ceramic plates of the known fuel pump low strength of the plastic housing parts gets through the ribs in the channels balanced.
Eine Verbindung der Gehäuseteile erfordert gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einen besonders geringen konstruktiven Aufwand, wenn die Gehäuseteile miteinander verschraubt sind, wobei eines der aus Kunststoff gefertigten Gehäuseteile Aufnahmen für Muttern aus Metall hat. Die Muttern aus Metall stellen eine ausreichende Stabilität der erfindungsgemäßen Kraftstoffpumpe sicher.A Connection of the housing parts requires according to a another advantageous embodiment of the invention a particular low design effort when the housing parts screwed together are, wherein one of the plastic housing parts Recordings for Has metal nuts. The nuts made of metal provide sufficient stability the fuel pump according to the invention for sure.
Die Erfindung lässt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist eine davon in der Zeichnung dargestellt und wird nachfolgend beschrieben. Diese zeigt inThe Invention leaves numerous embodiments to. To further clarify its basic principle is one of them shown in the drawing and will be described below. These shows in
