Description

Beschreibungdescription

Zur Montage in einem Kraftstoffbehälter vorgesehene FördereinheitDelivery unit intended for installation in a fuel tank

Die Erfindung betrifft eine zur Montage in einem Kraftstoffbehälter vorgesehene Fördereinheit mit einer in einem Schwalltopf angeordneten Kraftstoffpumpe und mit einer Saugstrahlpumpe zur Förderung von Kraftstoff in den Schwalltopf, wobei ein Mischrohr der Saugstrahlpumpe im Wesentlichen vertikal angeordnet ist.The invention relates to a delivery unit provided for mounting in a fuel tank with a fuel pump arranged in a baffle and with a suction jet pump for delivering fuel into the baffle, a mixing tube of the suction jet pump being arranged essentially vertically.

Solche Fördereinheiten werden in heutigen Kraftfahrzeugen häufig eingesetzt und sind aus der Praxis bekannt. Die Saug- Strahlpumpe wird in der Regel von der Kraftstoffpumpe mitSuch conveyor units are often used in today's motor vehicles and are known from practice. The suction jet pump is usually used by the fuel pump

Treibmittel versorgt und saugt Kraftstoff von dem außerhalb des Schwalltopfes befindlichen Bereich des Kraftstoffbehälters an. Hierdurch wird sichergestellt, dass der Schwalltopf ständig mit Kraftstoff gefüllt ist. Die vertikale Einbaulage der Saugstrahlpumpe ermöglicht den Einsatz eines besonders lang gestalteten Mischrohrs.Propellant supplies and sucks fuel from the area of the fuel tank located outside the swirl pot. This ensures that the swirl pot is constantly filled with fuel. The vertical installation position of the suction jet pump enables the use of a particularly long mixing tube.

Der Erfindung liegt das Problem zugrunde, eine Fördereinheit der eingangs genannten Art so zu gestalten, dass sie ein Her- ausspritzen des von der Saugstrahlpumpe geförderten Kraftstoffs aus dem Schwalltopf zuverlässig vermeidet.The invention is based on the problem of designing a delivery unit of the type mentioned at the outset in such a way that it reliably prevents the fuel delivered by the suction jet pump from spraying out of the swirl pot.

Dieses Problem wird erfindungsgemäß dadurch gelöst, dass an dem Auslass des Mischrohrs der Saugstrahlpumpe eine Umlenkung zur Führung des von der Ξaugstrahlpumpe geförderten Kraftstoffs in den Schwalltopf angeordnet ist.This problem is solved according to the invention in that a deflection for guiding the fuel delivered by the suction jet pump into the surge pot is arranged at the outlet of the mixing tube of the suction jet pump.

Durch diese Gestaltung gelangt der von der Saugstrahlpumpe geförderte Kraftstoff nach dem Austritt aus dem Mischrohr ge- gen die Umlenkung. Da die Umlenkung den geförderten Kraft- As a result of this design, the fuel delivered by the suction jet pump arrives at the deflection after it leaves the mixing tube. Since the redirection of the

stoff in den Schwalltopf lenkt, wird ein Herausspritzen des Kraftstoffs aus dem Schwalltopf zuverlässig vermieden. Hierdurch kann sich, das Mischrohr nahezu bis zu der oberen Begrenzung des Schwalltopfes erstrecken. Die Umlenkung des ge- förderten Kraftstoffs ist dabei unabhängig von der Förderleistung der Saugstrahlpumpe. Die Saugstrahlpumpe kann daher eine besonders hohe Förderleistung aufweisen.If the material steers into the baffle, the fuel is reliably prevented from splashing out of the baffle. As a result, the mixing tube can extend almost up to the upper limit of the swirl pot. The deflection of the delivered fuel is independent of the delivery rate of the suction jet pump. The suction jet pump can therefore have a particularly high delivery rate.

Die Umlenkung gestaltet sich gemäß einer vorteilhaften Wei- terbildung der Erfindung konstruktiv besonders einfach, wenn sie einen Bogen hat, wobei ein Teilbereich des Bogens die Öffnung des Mischrohres überdeckt und ein anderer Teilbereich über dem Schwalltopf angeordnet ist .According to an advantageous further development of the invention, the deflection is structurally particularly simple if it has an arc, wherein a partial area of the arc covers the opening of the mixing tube and another partial area is arranged above the swirl pot.

Bei einer besonders hohen Förderleistung der Saugstrahlpumpe lässt sich der Kraftstoff über einen großen Bereich verteilt in den Schwalltopf führen und dabei hohe Strömungsgeschwindigkeiten vermeiden, wenn die Umlenkung zwei aneinander angrenzende Bögen hat, wobei die Bögen in ihren aneinander an- grenzenden Bereichen über dem Mischrohr angeordnet sind und die freien Enden der Bögen das Mischrohr seitlich überragen.With a particularly high delivery rate of the suction jet pump, the fuel can be distributed over a large area into the baffle and high flow speeds can be avoided if the deflection has two adjacent bends, the bends being arranged in their adjacent areas above the mixing tube and the free ends of the bends protrude laterally from the mixing tube.

Die erfindungsgemäße Fördereinheit gestaltet sich konstruktiv besonders einfach, wenn die Umlenkung an dem Schwalltopf an- geordnet ist. Um eine einfache axiale Entformung des Schwalltopfes aus einer Spritzgussform zu gewährleisten, könnte die Umlenkung beispielsweise durch Umformung der Wandung des Schwalltopfes erzeugt werden.The delivery unit according to the invention is particularly simple in terms of construction if the deflection is arranged on the swirl pot. In order to ensure a simple axial demolding of the swirl pot from an injection mold, the deflection could be generated, for example, by reshaping the wall of the swirl pot.

Eine Umformung der Wandung des Schwalltopfes oder dessen aufwändige Fertigung lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn die Umlenkung an der Kraftstoffpumpe angeordnet ist. Hierdurch kann der Schwalltopf als einfach axial entformbares Spritz- According to another advantageous development of the invention, reshaping of the wall of the baffle or its elaborate production can be easily avoided if the deflection is arranged on the fuel pump. As a result, the baffle can be used as an easily axially demoldable spray

gussteil gefertigt werden. Die erfindungsgemäße Fördereinheit lässt sich hierdurch besonders kostengünstig fertigen.cast part to be made. The conveyor unit according to the invention can hereby be manufactured particularly inexpensively.

Die Montage der Umlenkung gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach, wenn die Umlenkung als separates, an der Kraftstoffpumpe oder dem Schwalltopf zu befestigendes Bauteil gestaltet ist.According to another advantageous development of the invention, the installation of the deflection is particularly simple if the deflection is designed as a separate component to be fastened to the fuel pump or the baffle.

Zur weiteren Vereinfachung der Montage der Umlenkung trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn die Umlenkung mit einem Bauteil der Kraftstoffpumpe eine bauliche Einheit bildet. Vorzugsweise handelt es sich bei dem Bauteil um einen Kontakte für den Elektromotor tragenden Deckel. Da der Deckel in der Regel ohnehin als separat zu montierendes Bauteil gestaltet ist, wird die Umlenkung gleichzeitig mit der Montage der Kraftstoffpumpe montiert.According to another advantageous development of the invention, it further contributes to further simplifying the assembly of the deflection if the deflection forms a structural unit with a component of the fuel pump. The component is preferably a contact for the cover carrying the electric motor. Since the cover is usually designed as a component to be installed separately, the deflection is installed at the same time as the fuel pump is installed.

Zur weiteren Verringerung der Fertigungskosten der erfindungsgemäßen Fördereinheit trägt es bei, wenn die Umlenkung einstückig mit dem Bauteil der Kraftstoffpumpe gefertigt ist.It contributes to a further reduction in the manufacturing costs of the delivery unit according to the invention if the deflection is made in one piece with the component of the fuel pump.

Das Mischrohr der Saugstrahlpumpe könnte mit dem Schwalltopf einteilig gefertigt sein. Zur weiteren Vereinfachung der Montage der erfindungsgemäßen Fördereinheit trägt es jedoch bei, wenn das Mischrohr der Saugstrahlpumpe mit der Förderpumpe als vormontierbare bauliche Einheit gestaltet ist. Im einfachsten Fall kann das Mischrohr mit der Kraftstoffpumpe einteilig gestaltet sein.The mixing tube of the suction jet pump could be made in one piece with the baffle. To further simplify the assembly of the delivery unit according to the invention, however, it is helpful if the mixing tube of the suction jet pump with the delivery pump is designed as a preassembled structural unit. In the simplest case, the mixing tube with the fuel pump can be designed in one piece.
