Description

Die Erfindung betrifft eine in einem Schwalltopf eines Kraftstoffbehälters eines Kraftfahrzeuges angeordnete Fördereinheit, mit einer zur Förderung von Kraftstoff zu einer Brennkraftmaschine des Kraftfahrzeuges vorgesehenen Kraftstoffpumpe, mit einer mit der Kraftstoffpumpe verbundenen Saugstrahlpumpe zur Förderung von Kraftstoff aus dem Kraftstoffbehälter in den Schwalltopf und mit einem Pumpenhalter zur Halterung der Kraftstoffpumpe in dem Schwalltopf.The invention relates to a in a baffle Fuel tank of a motor vehicle arranged Conveyor unit, with a for the conveyance of fuel too provided an internal combustion engine of the motor vehicle Fuel pump, with one connected to the fuel pump Suction jet pump to deliver fuel from the fuel tank in the baffle and with one Pump holder for holding the fuel pump in the Swirl pot.

Solche Fördereinheiten werden in heutigen Kraftfahrzeugen häufig eingesetzt und sind aus der Praxis bekannt. Der Pumpenhalter der bekannten Fördereinheit ist zweiteilig gestaltet und hat einen in einer im Bodenbereich des Schwalltopfes angeordneten Öffnung eingesetzten Dichtring und einen an einem Deckel des Schwalltopfes befestigten Arm. Die Kraftstoffpumpe wird von dem Arm gegen den Dichtring vorgespannt. Die Saugstrahlpumpe wird von der Kraftstoffpumpe mit Kraftstoff versorgt und saugt den Kraftstoff aus dem Kraftstoffbehälter durch die Öffnung an. Die Saugstrahlpumpe ist in einem Gehäuse der Kraftstoffpumpe integriert. Such conveyor units are used in today's motor vehicles frequently used and are known from practice. The Pump holder of the known delivery unit is in two parts designed and has one in the bottom area of the Baffle arranged opening inserted sealing ring and one attached to a lid of the baffle Poor. The fuel pump is from the arm against the Prestressed sealing ring. The suction jet pump is from the Fuel pump supplies fuel and sucks the Fuel from the fuel tank through the opening on. The suction jet pump is in a housing of the fuel pump integrated.

Nachteilig bei der bekannten Fördereinheit ist, daß die Kraftstoffpumpe mit der Saugstrahlpumpe ein konstruktiv sehr aufwendiges Bauteil darstellt. Weiterhin erschwert die Saugstrahlpumpe Wartungsarbeiten an der Kraftstoffpumpe.A disadvantage of the known conveyor unit is that the Fuel pump with the suction jet pump a constructive represents a very complex component. Still difficult the suction jet pump does maintenance work on the fuel pump.

Der Erfindung liegt das Problem zugrunde, eine Fördereinheit der eingangs genannten Art so zu gestalten, daß sie möglichst einfach aufgebaut und zu montieren ist.The invention is based on the problem of a conveyor unit of the type mentioned in such a way that they is as simple as possible to assemble and assemble.

Dieses Problem wird erfindungsgemäß dadurch gelöst, daß die Saugstrahlpumpe mit dem Pumpenhalter und/oder dem Schwalltopf als bauliche Einheit gestaltet ist.This problem is solved according to the invention in that the suction jet pump with the pump holder and / or the Swirl pot is designed as a structural unit.

Durch diese Gestaltung lassen sich die Saugstrahlpumpe und die Kraftstoffpumpe einfach getrennt in dem Schwalltopf montieren und demontieren. Wartungsarbeiten an der Kraftstoffpumpe werden dank der Erfindung nicht von der Saugstrahlpumpe behindert und gestalten sich daher sehr einfach. Die Kraftstoffpumpe ist hierdurch besonders einfach aufgebaut und läßt sich zudem kostengünstig fertigen. Ein weiterer Vorteil dieser Gestaltung ist eine einfache sortenreine Trennung von Materialien bei der Demontage der erfindungsgemäßen Fördereinheit, da der Pumpenhalter wie die Saugstrahlpumpe und der Schwalltopf in der Regel aus Kunststoff gefertigt werden und die Kraftstoffpumpe meist Gehäusedeckel und einen Gehäusemantel aus Metall aufweist.This design allows the suction jet pump and the fuel pump simply separated in the baffle assemble and disassemble. Maintenance work on the Fuel pump are not thanks to the invention The suction jet pump is very difficult and therefore very difficult to design simple. This makes the fuel pump particularly simple built and can also be manufactured inexpensively. Another advantage of this design is a simple one sorted separation of materials during disassembly the delivery unit according to the invention, since the pump holder like the suction jet pump and the baffle in the Usually be made of plastic and the fuel pump mostly housing cover and a metal casing having.

Zur weiteren Vereinfachung der Montage der erfindungsgemäßen Fördereinheit trägt es bei, wenn der am Boden des Schwalltopfes befestigte Pumpenhalter eine Rastverbindung mit der Kraftstoffpumpe hat. Im einfachsten Fall kann hierdurch auf eine Vorspannung der Kraftstoffpumpe mittels eines sich an dem Deckel des Schwalltopfes abstützenden Arms verzichtet werden. To further simplify the assembly of the invention Conveyor unit contributes if the at the bottom of the Baffle attached pump holder a snap connection with the fuel pump. In the simplest case it can hereby by means of a preload on the fuel pump one supported on the cover of the baffle Arms are waived.

Die Kraftstoffpumpe wird gemäß einer anderen vorteilhaften Weiterbildung der Erfindung zuverlässig in ihrer vorgesehenen Lage gehalten, wenn der Pumpenhalter einen umlaufenden, einen unteren Bereich der Kraftstoffpumpe umgreifenden Rand und die Rastverbindung einen auf dem freien Ende des Randes angeordneten, radial nach innen weisenden Vorsprung aufweist.The fuel pump is advantageous according to another Further development of the invention reliably in its intended Held in position when the pump holder has a rotating, encompassing a lower area of the fuel pump Edge and the snap connection one on the Free end of the edge arranged radially inwards has a pointing projection.

Zur weiteren Vereinfachung der Montage und der Demontage der erfindungsgemäßen Fördereinheit trägt es bei, wenn eine Verbindung des Pumpenhalters mit dem Boden des Schwalltopfes formschlüssig gestaltet ist.To further simplify assembly and disassembly the conveyor unit according to the invention contributes if connect the pump holder to the bottom of the Swirl pot is designed to be form-fitting.

Die Saugstrahlpumpe könnte einstückig mit dem Pumpenhalter gestaltet sein. Da jedoch die Saugstrahlpumpe eine Düse und ein von der Düse beabstandetes Mischrohr aufweist, führt dies zu einer komplizierten Gestaltung des Pumpenhalters. Der Pumpenhalter läßt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders einfach fertigen, wenn der Boden des Schwalltopfes einen Teilbereich eines Mischrohrs der Saugstrahlpumpe aufweist.The suction jet pump could be made in one piece with the pump holder be designed. However, since the suction jet pump is a Nozzle and a mixing tube spaced from the nozzle, this leads to a complicated design of the Pump holder. The pump holder can be made according to another advantageous development of the invention particularly just make it when the bottom of the baffle Has partial area of a mixing tube of the suction jet pump.

Die Fertigung der Saugstrahlpumpe und der daran angrenzenden Bauteile gestaltet sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders kostengünstig, wenn eine Düse und das Mischrohr der Saugstrahlpumpe jeweils zu einer Hälfte in dem Schwalltopf und zur anderen Hälfte in dem Pumpenhalter angeordnet sind. Durch diese Gestaltung ist die Saugstrahlpumpe längs geteilt und läßt sich daher zusammen mit dem Schwalltopf und dem Pumpenhalter einfach in axial entformbaren Spritzgußformen fertigen. The production of the suction jet pump and the adjoining one Components are designed according to another advantageous one Development of the invention is particularly cost-effective, if a nozzle and the mixing tube of the suction jet pump one half each in the baffle and one other half are arranged in the pump holder. By this design divides the suction jet pump lengthways and can therefore be used together with the baffle and the Pump holder simply in axially demouldable injection molds manufacture.

Zur weiteren konstruktiven Vereinfachung der erfindungsgemäßen Fördereinheit trägt es bei, wenn die Saugstrahlpumpe formschlüssig mit dem Pumpenhalter verbunden ist.To further constructively simplify the invention Conveyor unit helps when the suction jet pump is positively connected to the pump holder.

Die Saugstrahlpumpe könnte beispielsweise wie bei der bekannten Fördereinheit einen im Bereich eines zu der Brennkraftmaschine führenden Auslaßkanals angeordneten Abzweig für die Saugstrahlpumpe aufweisen. Da jedoch die Brennkraftmaschine des Kraftfahrzeuges einen höheren Druck erfordert als die Saugstrahlpumpe, erfordert dies ein kostenintensives, in dem Abzweig angeordnetes Druckminderventil. Ein solches kostenintensives Druckminderventil läßt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach vermeiden, wenn die Kraftstoffpumpe als Peripheralpumpe oder Seitenkanalpumpe ausgebildet ist und wenn eine Düse der Saugstrahlpumpe mit einem im mittleren Bereich einer Förderkammer der Kraftstoffpumpe angeordneten Abzweig verbunden ist. Hierdurch ist der Abzweig an einer Stelle in der Kraftstoffpumpe angeordnet, an der sich selbständig der vorgesehene Druck einstellt.The suction jet pump could, for example, as in the known one Conveyor unit one in the area of one Internal combustion engine leading exhaust port arranged Have a branch for the suction jet pump. However, since the Internal combustion engine of the motor vehicle a higher Pressure requires than the suction jet pump, this requires an expensive pressure reducing valve arranged in the branch. Such a costly pressure reducing valve can be according to another advantageous development simply avoid the invention if the Fuel pump as peripheral pump or side channel pump is formed and if a nozzle of the suction jet pump with one in the middle of a delivery chamber Fuel pump arranged branch is connected. Hereby is the branch at one point in the fuel pump arranged, on which the intended Pressure.

In einer weiteren vorteilhaften Ausgestaltung wird die Saugstrahlpumpe über eine eigene Pumpstufe mit Kraftstoff versorgt. Diese zusätzliche Pumpstufe kann in einer Peripheralpumpe oder Seitenkanalpumpe besonders kostengünstig in einem Laufrad mit der Hauptpumpstufe angeordnet sein.In a further advantageous embodiment, the Suction jet pump with its own pump stage with fuel provided. This additional pump stage can be done in a peripheral pump or side channel pump particularly inexpensive be arranged in an impeller with the main pump stage.
