Description

Gegenstand der Erfindung ist eine Saugstrahlpumpe mit verbesserter Saugwirkung. Saugstrahlpumpen werden beispielsweise in Kraftstoffbehältern von Kraftfahrzeugen eingesetzt, um Kraftstoff aus einem Bereich des Kraftstoffbehälters in einen anderen Bereich zu fördern.The invention relates to a suction jet pump with improved suction. Suction jet pumps are used, for example, in fuel tanks Motor vehicles used to remove fuel from an area of the fuel tank to promote another area.

Saugstrahlpumpen werden heutzutage in Kraftstoffbehältern von Kraftfahrzeugen eingesetzt und sind damit bekannt. Sie haben die Aufgabe, Kraftstoff aus entfernten und tieferliegenden Bereichen des Kraftstoffbehälters zur Fördereinheit oder in einen Schwalltopf zu fördern. Die Saugstrahlpumpe besteht dabei im wesentlichen aus einem Treibstrahlrohr, einer Ansaugöffnung und einem Mischrohr. Die über das Treibstrahlrohr der Saugstrahlpumpe zugeführte Menge an Flüssigkeit tritt unter Druck aus der das Treibstrahlrohr begrenzenden Treibstrahldüse aus und anschließend in das Mischrohr ein. Die Ansaugöffnung für die zu fördernde Flüssigkeit ist zwischen der Treibstrahldüse und dem Mischrohr angeordnet. Der in das Mischrohr eintretende Treibstahl erzeugt vor dem Mischrohr einen Unterdruck, so daß die zu fördernde Flüssigkeit über die Ansaugöffnung in das Mischrohr angesaugt wird. Der Wirkungsgrad einer Saugstrahlpumpe ist dabei von vielen Faktoren abhängig. So beeinflussen beispielsweise die Länge des Mischrohres und andere geometrische Faktoren den Wirkungsgrad. Der allgemeine Nachteil von Saugstrahlpumpen besteht in ihrem relativ niedrigen Wirkungsgrad von ca. 20 bis 30 %.Suction jet pumps are nowadays used in fuel tanks in motor vehicles used and are therefore known. Your job is to fuel out distant and deeper areas of the fuel tank to the delivery unit or to promote in a baffle. The suction jet pump is there essentially of a propulsion jet pipe, a suction opening and a Mixing tube. The quantity fed through the jet nozzle of the suction jet pump liquid emerges under pressure from the boundary of the jet tube Jet nozzle and then into the mixing tube. The suction opening for the liquid to be pumped is between the jet nozzle and the Mixing tube arranged. The driving steel entering the mixing tube produces before the mixing tube a negative pressure, so that the liquid to be pumped over the Suction opening is sucked into the mixing tube. The efficiency of one The suction jet pump is dependent on many factors. So influence, for example the length of the mixing tube and other geometric factors Efficiency. The general disadvantage of suction jet pumps is their relatively low efficiency of approx. 20 to 30%.

Es ist bekannt, daß eine gute Saugwirkung dadurch erreicht wird, daß die Mischrohrlänge mehr als das Zehnfache des Mischrohrdurchmessers beträgt. Aufgrund der räumlichen Gegebenheiten in einem Kraftstoffbehälter sind aber gerade diese geometrischen Anforderungen oft nicht realisierbar, so daß der ohnehin geringe Wirkungsgrad noch weiter verschlechtert wird.It is known that a good suction effect is achieved in that the Mixing tube length is more than ten times the mixing tube diameter. However, due to the spatial conditions in a fuel tank precisely these geometrical requirements often cannot be realized, so that the anyway low efficiency is further deteriorated.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Saugstrahlpumpe mit verbesserter Saugwirkung zu schaffen, die einfach gebaut ist und keinen großen Bauraum beansprucht.The invention is therefore based on the object of having a suction jet pump to create improved suction that is simple in construction and not a large one Space required.

Gelöst wird die Aufgabe mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind in den Ansprüchen 2 bis 8 beschrieben.The object is achieved with the features of claim 1. Advantageous refinements are described in claims 2 to 8.

Überraschenderweise wurde gefunden, daß das der Erfindung zugrundeliegende Problem mit einer Saugstrahlpumpe gelöst wird, deren Treibstrahldüse und Diffusor derart ausgebildet sind, daß sich der Treibstrahl bereits im Diffusor vollständig an den Umfang des Diffusors legt. Dadurch wird ein sehr schneller Flüssigkeitsverschluß erreicht, der zu einem sehr hohen Unterdruck führt. Erfindungswesentlich ist, daß die Treibstrahldüse und der Diffusor aufeinander abgestimmt sind. Insbesondere die Formgebung der Treibstrahldüse ermöglicht die Aufweitung des Treibstrahls schon kurz nach Verlassen der Treibstrahldüse.Surprisingly, it was found that the basis of the invention Problem with a suction jet pump is solved, its jet nozzle and the diffuser are designed such that the driving jet is already in the diffuser completely on the circumference of the diffuser. This will make a very achieved rapid liquid closure, which leads to a very high negative pressure leads. It is essential to the invention that the jet nozzle and the diffuser are on top of each other are coordinated. In particular, the shape of the jet nozzle enables the expansion of the propellant jet shortly after leaving the Jet nozzle.

Der Vorteil der erfindungsgemäßen Saugstrahlpumpe besteht in ihrer gegenüber bekannten Saugstrahlpumpen verbesserten Saugwirkung, der auf den schnellen Flüssigkeitsverschluß im Diffusor zurückgeführt wird. Darüber hinaus besitzt die Saugstrahlpumpe einen sehr einfachen Aufbau und beansprucht wenig Platz.The advantage of the suction jet pump according to the invention is that of it known suction jet pumps improved suction, which on the rapid liquid closure in the diffuser is returned. Furthermore the suction jet pump has a very simple structure and is stressed little space.

In einer besonders vorteilhaften Ausgestaltung ist die Düsenöffnung der Treibstrahldüse derart gestaltet, daß sie einen Flachstrahl erzeugt. Der Diffusor besitzt in diesem Fall einen an den Flachstrahl angepaßten elliptischen Einlaufkonus.In a particularly advantageous embodiment, the nozzle opening is Driving jet nozzle designed such that it generates a flat jet. The diffuser in this case has an elliptical inlet cone adapted to the flat jet.

Besonders vorteilhaft ist eine Düsenöffnung, die eine quer verlaufende Kerbe besitzt. Dadurch wird der Treibstrahl fächerförmig aufgeweitet. In anderen Ausgestaltungen ist in der Düsenöffnung ein Steg angeordnet, der den Treibstrahl teilt und somit den Flachstrahl erzeugt. Es ist aber auch eine Düsenöffnung denkbar, die mehrere in einer Linie angeordnete Öffnungen besitzt, so daß die Einzelstrahlen sich zu einem Flachstrahl formieren.A nozzle opening, which has a transverse notch, is particularly advantageous owns. As a result, the driving jet is expanded in a fan shape. In other configurations a web is arranged in the nozzle opening, which contains the driving jet divides and thus generates the flat jet. But it is also a nozzle opening conceivable, which has a plurality of openings arranged in a line, so that the Form individual beams into a flat beam.

Ein ebenfalls schneller Flüssigkeitsverschluß im Mischrohr wird erreicht, wenn die Achse der Treibstrahldüse in einem kleinen Winkel zur Achse des Mischrohrs steht. Dadurch trifft der Treibstrahl nicht axial, sondern schräg auf das Mischrohr. Diese Vergrößerung des Auftreffwinkels hat den noch schnelleren Flüssigkeitsabschluß im Mischrohr zur Folge, um somit ebenfalls zu einer verbesserten Saugwirkung zu führen.An equally quick liquid seal in the mixing tube is achieved if the axis of the jet nozzle at a small angle to the axis of the mixing tube stands. As a result, the propellant jet does not hit it axially, but at an angle Mixing tube. This increase in the angle of incidence has the even faster Conclusion of liquid in the mixing tube in order to also improve Lead suction.

An einem Ausführungsbeispiel wird die Erfindung näher erläutert. Die Figuren zeigen dabei in Figur 1 einen Schnitt durch eine erfindungsgemäße Saugstrahlpumpe, Figur 2 die Draufsicht auf das Mischrohr mit elliptischem Diffusor.The invention is explained in more detail using an exemplary embodiment.
