Description
Die Erfindung betrifft eine Kraftstofffördereinrichtung nach der Gattung des Anspruchs 1.The invention relates to a fuel delivery device according to the Genus of claim 1.
Eine solche Kraftstoffördereinrichtung ist durch die GB-A-2 271 327 bekannt. Diese Kraftstoffördereinrichtung weist einen Kraftstoffvorratstank auf, in dem ein Behälter angeordnet ist, aus dem ein Förderaggregat Kraftstoff fördert. Die Kraftstoffördereinrichtung weist außerdem eine Saugstrahlpumpe für Kraftstoff auf, mit einer an einer Kraftstoffleitung angeschlossenen Düse und einem dieser nachgeordneten Mischrohr, zwischen denen eine Öffnung gebildet ist, durch die aus der Düse austretender Kraftstoff die Saugstrahlpumpe umgebenden Kraftstoff in das Mischrohr mitführt. Durch die Saugstrahlpumpe wird Kraftstoff aus dem Kraftstoffvorratstank in den Behälter gefördert. Das Mischrohr weist an seinem der Düse abgewandten Endbereich eine angeschrägte Öffnung auf, die sich in Einbaulage des Mischrohrs bis in dessen oberen Umfangsbereich erstreckt. Das Mischrohr ragt in eine vertikal verlaufende Kraftstoffleitung hinein, die in einem oberen Bereich des Behälters mündet. Durch die angeschrägte Öffnung des Mischrohrs wird aus diesem austretender Kraftstoff in die vertikal verlaufende Kraftstoffleitung umgelenkt. Die Kraftstoffleitung, an die die Düse angeschlossen ist, ist eine Rücklaufleitung, durch die vom Förderaggregat zuviel geförderter Kraftstoff wieder in den Vorratstank zurückgeführt wird. Der durch die Rücklaufleitung strömende Kraftstoff ist oftmals stark erwärmt, so daß dieser an der Saugstrahlpumpe ausgast und Dampfblasen entstehen können, die den Betrieb der Saugstrahlpumpe beeinträchtigen, so daß diese nicht genügend Kraftstoff in den Behälter fördert. Die Dampfblasen strömen dabei durch die vertikale Kraftstoffleitung nach oben in den Behälter und behindern unter Umständen die Strömung des geförderten Kraftstoffs in der vertikalen Kraftstoffleitung.Such a fuel delivery device is known from GB-A-2 271 327 known. This fuel delivery device has a fuel storage tank on, in which a container is arranged which a fuel pump delivers. The fuel delivery device also has a suction jet pump for fuel with a nozzle connected to a fuel line and one of these downstream mixing tube, between which one Opening is formed through the fuel emerging from the nozzle the suction jet pump surrounding fuel into the mixing tube carries along.

Die erfindungsgemäße Kraftstoffördereinrichtung mit den Merkmalen gemäß dem Anspruch 1 hat demgegenüber den Vorteil, daß an der Saugstrahlpumpe entstehende Gasblasen beim Eintritt in den Behälter durch die wenigstens eine Öffnung des Mischrohrs nach oben entweichen können und damit der Betrieb der Saugstrahlpumpe auch bei erwärmtem Kraftstoff sichergestellt ist.The fuel delivery device according to the invention with the features according to claim 1 has the advantage that The gas jet produced by the suction jet pump when entering the Container through the at least one opening of the mixing tube can escape at the top and thus the operation of the suction jet pump is ensured even with heated fuel.
In den abhängigen Ansprüchen sind vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Kraftstoffördereinrichtung angegeben. Advantageous embodiments are in the dependent claims and further developments of the fuel delivery device according to the invention specified.
Drei Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Es zeigen Figur 1 ausschnittsweise einen Kraftstoffvorratstank mit einer in diesem angeordneten Saugstrahlpumpe, Figur 2 ausschnittsweise einen Längsschnitt durch die Saugstrahlpumpe gemäß einem ersten Ausführungsbeispiel in vergrößerter Darstellung, Figur 3 ausschnittsweise eine Ansicht der Saugstrahlpumpe von Figur 2 in Pfeilrichtung III, Figur 4 ausschnittsweise einen Längsschnitt durch die Saugstrahlpumpe gemäß einem zweiten Ausführungsbeispiel, Figur 5 ausschnittsweise eine Ansicht der Saugstrahlpumpe von Figur 4 in Pfeilrichtung V in Figur 4 und Figur 6 ausschnittsweise eine Ansicht der Saugstrahlpumpe gemäß einem dritten Ausführungsbeispiel. Three embodiments of the invention are in the drawing shown and in the following description explained. FIG. 1 shows a detail of a fuel storage tank with a suction jet pump arranged in it, 2 shows a longitudinal section by the suction jet pump according to a first embodiment in an enlarged view, Figure 3 detail a view of the suction jet pump of Figure 2 in the direction of the arrow III, Figure 4 a section of a longitudinal section the suction jet pump according to a second embodiment, Figure 5 shows a partial view of the suction jet pump of Figure 4 in the direction of arrow V in Figure 4 and Figure 6 in sections a view of the suction jet pump according to one third embodiment.
In Figur 1 ist eine Kraftstoffördereinrichtung mit einem Kraftstoffvorratstank 10 eines Kraftfahrzeugs
dargestellt, in dem nahe dessen Boden 11 ein Behälter
12 angeordnet ist. Aus dem Behälter 12 saugt ein Aggregat 14
an, das Kraftstoff, der bekanntlich eine verdampfungskritische
Flüssigkeit ist, zur Brennkraftmaschine 16 des Kraftfahrzeugs
fördert. Das Förderaggregat 14 fördert mehr Kraftstoff
als die Brennkraftmaschine 16 verbraucht und der überschüssige
Kraftstoff gelangt über eine Rücklaufleitung 18
zurück in den Vorratstank 10. An die Rücklaufleitung 18 ist
eine nahe dem Boden 11 des Vorratstanks 10 angeordnete Saugstrahlpumpe
20 angeschlossen. Die Saugstrahlpumpe 20 weist
eine an die Rücklaufleitung 18 angeschlossene Düse 22 auf,
die als Venturirohr ausgebildet ist und einen Mündungsabschnitt
23 mit gegenüber dem lichten Querschnitt der Rücklaufleitung
18 reduziertem Mündungsquerschnitt aufweist. Mit
axialem Abstand ist der Düse 22 ein Mischrohr 26 nachgeordnet,
dessen lichter Querschnitt größer ist als der Mündungsquerschnitt
der Düse 22. Durch den axialen Abstand zwischen
der Düse 22 und dem Mischrohr 26 ist zwischen diesen beiden
Teilen eine Öffnung 27 vorhanden, beispielsweise in Form eines
Ringspalts, durch die Kraftstoff aus dem Vorratstank 10
in das Mischrohr 26 gelangen kann. Die Düse 22 ist dabei außerhalb
des Behälters 12 im Vorratstank 10 angeordnet und
das Mischrohr 26 ragt mit seinem der Düse 22 abgewandten
Endbereich 28 durch eine seitliche Wand 13 in den Behälter
12 hinein. Dem Mischrohr 26 kann innerhalb des Behälters 12
ein nicht dargestelltes Rückschlagventil zugeordnet sein,
durch das verhindert wird, daß Kraftstoff aus dem Behälter
12 durch das Mischrohr 26 abfließt.FIG. 1 shows a fuel delivery device with a
Während des Betriebs fördert das Aggregat 14 Kraftstoff aus
dem Behälter 12 zur Brennkraftmaschine 16. Die von der
Brennkraftmaschine 16 nicht verbrauchte Kraftstoffmenge gelangt
über die Rücklaufleitung 18 in den Vorratstank 10 zurück.
Der durch die Rücklaufleitung 18 fließende, unter dem
vom Förderaggregat 14 erzeugten Förderdruck stehende Kraftstoff
strömt durch den Mündungsabschnitt 23 der Düse 22 aus
und reißt dabei Kraftstoff aus dem Vorratstank 10 durch die
Öffnung 27 in das Mischrohr 26 mit. Durch die Saugstrahlpumpe
20 wird somit zusätzlich zu dem über die Rücklaufleitung
18 fließenden Kraftstoff noch Kraftstoff aus dem Vorratstank
10 in den Behälter 12 gefördert, in dem sich somit ständig
eine für den Betrieb der Brennkraftmaschine 16 ausreichende
Kraftstoffmenge befindet. Die Saugstrahlpumpe 20 kann auch
bei einem zerklüfteten Vorratstank 10 verwendet werden, bei
dem der Behälter 12 in einem Bereich des Vorratstanks 10 angeordnet
ist, der von anderen Bereichen des Vorratstanks
durch Höcker oder andere Erhebungen getrennt ist, so daß aus
diesen Bereichen kein Kraftstoff in den Bereich mit dem Behälter
12 fließen kann. In diesem Fall wird durch die Saugstrahlpumpe
20 Kraftstoff aus den anderen Bereichen des Vorratstanks
10 in den Bereich gefördert, in dem der Behälter
12 angeordnet ist.During operation, the
In den Figuren 2 und 3 ist die Saugstrahlpumpe 20 gemäß einem
ersten Ausführungsbeispiel dargestellt. In Figur 2 ist
ausschnittsweise die Düse 22 mit ihrem Mündungsabschnitt 23
sowie das die Wand 13 des Behälters 12 durchdringende Mischrohr
26 dargestellt. Das Mischrohr 26 weist in seinem der
Düse 22 abgewandten, im Behälter 12 angeordneten Endbereich
28 an seinem in Einbaulage oberen Umfangsbereich eine Öffnung
in Form eines Schlitzes 30 auf. Der Schlitz 30 verläuft
ausgehend vom Ende des Mischrohrs 26 etwa parallel zu dessen
Längsachse 29. Die Breite des Schlitzes 30 kann, wie in Figur
3 dargestellt, über dessen Länge etwa konstant sein oder
sich über dessen Länge verändern. Der durch die Rücklaufleitung
18 von der Brennkraftmaschine 16 in den Vorratstank 10
zurückfließende Kraftstoff ist unter Umständen stark erwärmt,
so daß beim Ausströmen des Kraftstoffs aus der Düse
22 Gasblasen entstehen, die in das Mischrohr 26 gelangen.
Die Gasblasen können durch den Schlitz 30 im Behälter 12
nach oben entweichen, so daß die Kraftstofförderung in den
Behälter 12 durch die Gasblasen nicht oder nur wenig beeinträchtigt
wird.In FIGS. 2 and 3, the
In den Figuren 4 und 5 ist die Saugstrahlpumpe 120 gemäß einem
zweiten Ausführungsbeispiel dargestellt, bei dem nur das
Mischrohr 126 gegenüber dem ersten Ausführungbeispiel modifiziert
ist, die übrigen Teile der Saugstrahlpumpe 120 aber
unverändert sind. Das Mischrohr 126 ragt mit seinem der Düse
22 abgewandten Ende durch die Wand 13 in den Behälter 12
hinein. In seinem im Behälter 12 angeordneten Endbereich 128
weist das Mischrohr 126 an seinem in Einbaulage oberen Umfangsbereich
eine Öffnung 130 auf, die gebildet ist, indem
der Endbereich 128 mit einer Anschrägung 132 versehen ist.
Die Anschrägung 132 verläuft zum Ende des Mischrohrs 126 hin
zur Längsachse 129 des Mischrohrs 126 hin geneigt. Durch
diese Anordnung der Anschrägung 132 vergrößert sich der
Querschnitt der Öffnung 130 zum Ende des Mischrohrs 126 hin.
Auch durch die Öffnung 130 können Gasblasen aus dem Mischrohr
126 nach oben austreten, so daß der Betrieb der Saugstrahlpumpe
120 durch diese nicht oder nur wenig beeinflußt
wird.In FIGS. 4 and 5, the
In Figur 6 ist ein drittes Ausführungsbeispiel der Saugstrahlpumpe
220 dargestellt, bei dem das Mischrohr 226 in
seinem Endbereich 228 an seinem Umfang mehrere Öffnungen 230
aufweist, die über den Umfang des Mischrohrs 226 verteilt
angeordnet sind und/oder in Richtung der Längsachse 229 des
Mischrohrs 226 zueinander versetzt angeordnet sind. Die
Querschnittsformen der Öffnungen 230 können dabei beliebig
sein.In Figure 6 is a third embodiment of the suction jet pump
220 shown, in which the
