Description

Die Erfindung betrifft eine Anordnung einer Brennstoffpumpe in einem Schlingertopf eines Brennstofftanks nach dem Oberbegriff des Patentanspruchs 1.The invention relates to an arrangement of a fuel pump in a swirl pot Fuel tanks according to the preamble of patent claim 1.

Es sind bereits derartige Anordnungen bekannt, bei denen Brennstoff über eine erste Pumpenstufe in den Schlingertopf hinein und über eine zweite Pumpenstufe zur Brennkraftmaschine gefördert wird. Hierbei wird der zur Brennkraftmaschine geförderte Brennstoff durch eine Elektromotorkammer geleitet und im Überschuß geförderter Brennstoff gelangt von der Brennkraftmaschine in den Tankstofftank zurück. Es liegt damit eine ausreichende Kühlung des Elektromotors vor.Such arrangements are already known in which fuel is supplied via a first one Pump stage into the swirl pot and via a second pump stage to Internal combustion engine is promoted. Here, the pumped to the internal combustion engine Fuel passed through an electric motor chamber and pumped in excess Fuel gets back into the tank tank from the internal combustion engine. So that's it adequate cooling of the electric motor.

Aus der DE-A1-43 32 446 ist eine Versorgungseinrichtung bekannt, bei der ein zwischen Brennstoffpumpe und Verteilerleiste eingesetzter Druckschalter in Abhängigkeit des Pumpenauslaßdrucks zwischen leitend und nichtleitend schaltet und dadurch die Brennstoffpumpe über eine Regelschaltung mit unterschiedlicher elektrischer Leistung versorgt wird, wenn der Pumpenauslaßdruck einen Schwellwert des Druckschalters über- oder unterschreitet.From DE-A1-43 32 446 a supply device is known in which a between Fuel pump and manifold used pressure switch depending on the Pump outlet pressure switches between conductive and non-conductive and thereby the Fuel pump via a control circuit with different electrical power is supplied when the pump outlet pressure exceeds a threshold value of the pressure switch or falls below.

Es hat sich nun gezeigt, daß bei dieser Vorrichtung eine unzulässige Erwärmung der Brennstoffpumpe auftritt.It has now been shown that an inadmissible heating of the Fuel pump occurs.

Hiervon ausgehend liegt der Erfindung daher die Aufgabe zugrunde, Maßnahmen aufzufinden, mit denen eine Zu- und Abschaltung der Brennstoffpumpe ohne unzulässige Erwärmung erreichbar ist.Proceeding from this, the invention is therefore based on the object of measures to find with which the fuel pump can be switched on and off without impermissible Heating is achievable.

Diese Aufgabe ist durch die im Kennzeichen des Patentanspruchs angegebenen Merkmale gelöst. This object is achieved by the features specified in the characterizing part of the claim solved.  

Die Erfindung basiert auf der Überlegung, daß eine dem Verbrauch der Brennkraftmaschine angepaßte Fördermenge den Elektromotor nicht ausreichend kühlt. Hiergegen wenden sich die erfinderischen Merkmale. Sie bewirken eine ausreichende Kühlung des Elektromotors.The invention is based on the consideration that the consumption of the internal combustion engine adjusted flow rate does not cool the electric motor sufficiently. Against this the inventive features. They ensure adequate cooling of the electric motor.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird nachfolgend beschrieben.An embodiment of the invention is shown in the drawing and will described below.

Die Zeichnung zeigt einen Schnitt durch eine erfindungsgemäße Anordnung einer Brennstoffpumpe 1 in einem Schlingertopf 2 eines Brennstofftanks 3 einer Fahr­ zeug-Brennkraftmaschine.The drawing shows a section through an inventive arrangement of a fuel pump 1 in a swirl pot 2 of a fuel tank 3 of a driving tool internal combustion engine.

Der Schlingertopf 2 weist eine nach oben geöffnete Speicherkammer 4 auf, in der zentral die Brennstoffpumpe 1 angeordnet ist und über eine erste Pumpenstufe 5 aus dem Brennstofftank 3 über einen Filter 6 Brennstoff ansaugt und in die Speicherkammer 4 fördert. Der im Überschuß geförderte Brennstoff füllt die Speicherkammer 4 bis zum Übe?lauf 7. Eine zweite Pumpenstufe 8 saugt aus der Speicherkammer 4 Brennstoff ab und fördert diesen, dem Bedarf der Brennkraftmaschine angepaßt, über eine Leitung 9 zur Brennkraftmaschine.The swirl pot 2 has an upwardly open storage chamber 4 , in which the fuel pump 1 is arranged centrally and draws fuel from the fuel tank 3 via a filter 6 via a first pump stage 5 and delivers it into the storage chamber 4 . The fuel delivered in excess fills the storage chamber 4 up to the overflow 7 . A second pump stage 8 sucks fuel out of the storage chamber 4 and conveys it, adapted to the needs of the internal combustion engine, via a line 9 to the internal combustion engine.

Erfindungsgemäß ist nun vorgesehen, daß die erste Pumpenstufe 5 durch eine Elektromotorkammer 10 der Brennstoffpumpe 1 in die Speicherkammer 4 des Schlingertopfes 2 fördert, so daß Elektromotor/Brennstoffpumpe durch die im Überschuß geförderte Brennstoffmenge gekühlt wird.According to the invention, it is now provided that the first pump stage 5 feeds through an electric motor chamber 10 of the fuel pump 1 into the storage chamber 4 of the swirl pot 2 , so that the electric motor / fuel pump is cooled by the excess amount of fuel delivered.
