Description
Die Erfindung betrifft eine Saugstrahlpumpeneinheit mit einer Saugstrahlpumpe, einem in eine Öffnung eines Kraftstoffbehälters einsetzbaren Halteflansch und einem Niederhalter, welcher zum Vorspannen der Saugstrahlpumpe von dem Halteflansch weg ausgebildet ist.The The invention relates to a suction jet pump unit with a suction jet pump, one in an opening a fuel tank insertable retaining flange and a hold-down, which for biasing the suction jet pump is formed away from the retaining flange.
Saugstrahlpumpeneinheiten
der vorstehenden Art werden derzeit in Kraftstoffbehältern heutiger Kraftfahrzeuge
eingebaut und sind deshalb bekannt. Sie dienen dazu, aus einer Kammer
des Kraftstoffbehälters
Kraftstoff über
eine Förderleitung
in eine zweite Kammer zu fördern. Üblicherweise
ist als Förderleitung
an der in dem Kraftstoffbehälter
angeordneten Saugstrahlpumpe ein Schlauch befestigt, der bis in die
zweite Kammer reicht. Als Treibmittel benutzt man häufig für solche
Saugstrahlpumpeneinheiten von einer Einspritzanlage des Kraftfahrzeugmotors über eine
Rücklaufleitung
zurückfließenden Kraftstoff.
Dazu ist die Saugstrahlpumpe mit einem weiteren Schlauch an einem
beispielsweise im Halteflansch angeordneten An schluß, zu dem
auch die Rücklaufleitung
führt,
angeschlossen (
Nachteilig ist es bei den bekannten Saugstrahlpumpeneinheiten, daß diese mit ihrem Niederhalter, ihren Schläuchen und dem Halteflansch ein recht sperriges Bauteil bilden, was sich bei einer Montage in einem Kraftstoffbehälter nachteilig bemerkbar macht.adversely it is in the known Saugstrahlpumpeneinheiten that this with its hold-down, its hoses and the retaining flange form a rather bulky component, resulting in a mounting in a fuel tank makes disadvantageous noticeable.
Der Erfindung liegt das Problem zugrunde, eine Saugstrahlpumpeneinheit der eingangs genannten Art so zu gestalten, daß ihr Ein- und Ausbau in eine Kammer eines Kraftstoffbehälters möglichst einfach ist.Of the Invention is based on the problem, a Saugstrahlpumpeneinheit of the type mentioned above so that their installation and removal in one Chamber of a fuel tank preferably easy.
Dieses Problem wird erfindungsgemäß dadurch gelöst, daß der Niederhalter und die Saugstrahlpumpe durch ein Gelenk miteinander verbunden sind.This Problem is inventively characterized solved, that the Downholder and the suction jet pump by a joint with each other are connected.
Diese Gestaltung erlaubt es, die Saugstrahlpumpeneinheit bei der Montage in eine langgestreckte Form zu bringen, so daß die Saugstrahlpumpe mit ihren Schläuchen voran in die Öffnung des Kraftstoffbehälters eingeführt werden kann. Diese Schläuche lassen sich im Kraftstoffbehälter zur zweiten Kammer hin umlenken. Anschließend wird der Niederhalter durch die Öffnung nachgeschoben, bis der Halteflansch gegen den Kraftstoffbehälter anliegt.These Design allows the Saugstrahlpumpeneinheit during assembly to bring in an elongated shape, so that the suction jet pump with their hoses ahead in the opening of the fuel tank introduced can be. Leave these hoses in the fuel tank divert to the second chamber. Then the hold-down is through the opening pushed until the retaining flange rests against the fuel tank.
Eine konstruktiv vorteilhafte Weiterbildung der Erfindung besteht darin, daß das Gelenk als Scharnier ausgebildet ist.A structurally advantageous development of the invention is that this Joint is designed as a hinge.
Die Saugstrahlpumpe läßt sich gegenüber dem Niederhalter in verschiedene Richtungen verschwenken und damit einfach in den Kraftstoffbehälter einführen, wenn das Gelenk eine Gelenkkugel und eine Kugelpfanne hat.The Suction jet pump can be compared to the Swing down hold-downs in different directions and thus easy in the fuel tank introduce, when the joint has a joint ball and a ball socket.
Eine für eine zuverlässige Funktion der Saugstrahlpumpeneinheit vorteilhafte Weiterbildung der Erfindung besteht darin, daß sie Mittel dauerhafter Ausrichtung der Saugstrahlpumpe gegenüber dem Niederhalter hat. Die Saugstrahlpumpe läßt sich damit im eingebauten Zustand nicht mehr gegenüber dem Halteteil oder dem Niederhalter verschwenken. Damit ist auch die Lage der Saugstrahlpumpe im Kraftstoffbehälter festgelegt. Diese Lage ist abhängig von der Geometrie des Kraftstoffbehälters, in den die Saugstrahlpumpeneinheit eingesetzt werden soll.A for one reliable Function of the Saugstrahlpumpeneinheit advantageous development of Invention is that they Means permanent alignment of the suction jet pump over the Hold-down has. The suction jet pump can thus be installed in the State no longer compared to that Swing holding part or the hold-down. This is also the Position of the suction jet pump in the fuel tank fixed. This location depends on the geometry of the fuel tank, in which the Saugstrahlpumpeneinheit is to be used.
Die Ausrichtung der Saugstrahlpumpe gestaltet sich besonders einfach, wenn sie eine zwischen der Saugstrahlpumpe und dem Niederhalter angeordnete und diese formschlüssig greifende Federklammer hat. Hierdurch läßt sich die Saugstrahlpumpeneinheit für die Montage in unterschiedlich gestalteten Kraftstoffbehältern vorbereiten, da eine solche Federklammer einfach an der Saugstrahlpumpeneinheit zu montieren und zu demontieren ist und damit leicht ausgewechselt werden kann.The Alignment of the suction jet pump is particularly easy, if they are arranged between the suction jet pump and the hold-down and this form-fitting has gripping spring clip. As a result, the Saugstrahlpumpeneinheit can be for the Prepare installation in differently designed fuel tanks because such a spring clip easy on the Saugstrahlpumpeneinheit to assemble and disassemble is easily replaced can be.
Bei einer Saugstrahlpumpeneinheit, bei welcher die Saugstrahlpumpe gegen einen Boden des Kraftstoffbehälters vorgespannt ist, wird diese selbständig ausgerichtet, wenn die Saugstrahlpumpe einen Fuß hat, welcher zum Anliegen an einen Boden des Kraftstoffbehälters vorgesehen ist.at a Saugstrahlpumpeneinheit, wherein the ejector against a bottom of the fuel tank is biased, this is independently aligned when the Suction jet pump has a foot, which is provided for abutment with a bottom of the fuel tank is.
Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung ihres Grundprinzips sind drei davon in der Zeichnung dargestellt und werden nachfolgend beschrieben. Diese zeigt inThe Invention leaves numerous embodiments to. To further clarify their basic principle are three of them shown in the drawing and are described below. This shows in
