Description
DEUTSCHESGERMAN
Die Erfindung bezieht sich auf eine Einrichtung im Kraftstoffbehälter für Brennkraftmaschinen, insbesondere von Kraftfahrzeugen zum Aufstauen einer für die Versorgung der Brennkraftmaschine ausreichenden Kraftstoffmenge bei auf das Fahrzeug einwirkenden Beschleunigungskräften in Gestalt eines um den Ansaugstutzen der Kraftstoffleitung angeordneten, mit dem Behälterboden abschließenden Staugehäuses, wobei zwei in sich geschlossen ausgebildete, verschieden große topfförmige, zentrisch ineinanderliegende Einzelgehäuse, ein äußeres und ein inneres Gehäuse, zwischen sich einen Ringkanal bilden, nach Patent 1 066 442.The invention relates to a device in the fuel tank for internal combustion engines, in particular of motor vehicles to accumulate a sufficient for the supply of the internal combustion engine Amount of fuel in the case of acceleration forces acting on the vehicle in the form of a Storage housing arranged around the intake port of the fuel line and flush with the bottom of the tank, whereby two cup-shaped cups of different sizes which are closed in themselves and lie centrally one inside the other Individual housing, an outer and an inner housing, between them form an annular channel U.S. Patent 1,066,442.
Die Erfindung besteht darin, daß die Kraftstoffrücklaufleitung in den Ringkanal tangential einmündet. Es hat diese Anordnung den Vorteil, daß die aus der Rücklaufleitung fließende Kraftstoffmenge einen längeren Weg zum Stauraum zurücklegen muß und deren unmittelbares Zusammentreffen mit der im Stauraum befindlichen Kraftstoffmenge verhindert. Beide Umstände tragen zu einer raschen Beruhigung und damit zu einer besseren Entschäumung und Entgasung des Kraftstoffes bei. Außerdem ermöglicht die Erfindung, den Tankinhalt praktisch restlos zu verbrauchen. The invention consists in that the fuel return line opens tangentially into the annular channel. This arrangement has the advantage that the amount of fuel flowing out of the return line must cover a longer way to the storage space and its direct coincidence with the im Prevents the amount of fuel in storage space. Both circumstances contribute to a rapid calming down and thus contribute to better defoaming and degassing of the fuel. In addition, the Invention to use up practically all of the tank contents.
In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel schematisch dargestellt. Es zeigen die Fig. 1 und 2 den Kraftstoffstauraum im Aufriß und Grundriß.In the drawing, the invention is shown schematically in one embodiment. Show it 1 and 2 show the fuel storage space in elevation and plan.
Auf dem Boden 120 des Kraftstoffbehälters ist das im wesentlichen zentral angeordnete und oben offene Kraftstoffsammeigehäuse 102 befestigt. Die den Stauraum E einschließende Gehäusewand 102 tangiert mit einer Abflachung 103 (Fig. 2) mit einer äußeren Zylinderwand 101. Die beiden Wände 101 und 102 begrenzen einen äußeren Ringraum 105j der, in der durch die Pfeile in Fig. 2 angedeuteten Strömungsrichtung des Kraftstoffes gesehen, unmittelbar vor der Abflachung 103 durch eine Öffnung 106 mit dem Stauraum E und unmittelbar hinter der Abflachung durch eine Öffnung 104 mit dem Hauptraum des Kraftstoffbehälters in Verbindung steht. In einigem Abstand vor der Öffnung 106 ragt von der Innenseite der Gehäusewand 102 eine angenähert tangential gegen einen zentral angeordneten Filterkörper 117 gerichtete Prallwand 116 quer ab. Um den Fuß des Filters 117 ist ein gegen dieses zu offener Ringkanal 122 herumgeführt, von welchem die z. B. an eine Kraftstofförderpumpe angeschlossene Saugleitung 113' abzweigt. The fuel collecting housing 102 , which is essentially arranged in the center and is open at the top, is fastened to the bottom 120 of the fuel tank. The housing wall 102 enclosing the storage space E is tangent to a flattened area 103 (FIG. 2) with an outer cylinder wall 101. The two walls 101 and 102 delimit an outer annular space 105j, viewed in the direction of flow of the fuel indicated by the arrows in FIG , directly in front of the flat 103 through an opening 106 with the storage space E and immediately behind the flat through an opening 104 with the main space of the fuel tank in connection. At some distance in front of the opening 106 , a baffle wall 116 directed approximately tangentially towards a centrally arranged filter body 117 protrudes transversely from the inside of the housing wall 102. To the foot of the filter 117 an against this too open ring channel 122 is led around, of which the z. B. connected to a fuel pump suction line 113 ' branches off.
Gemäß der Erfindung mündet die Rückleitung 114' für den Überschußkraftstoff, insbesondere im Bereich der Öffnung 104, tangential in den äußeren Ringraum 105 ein. Dadurch wird der aus der Leitung 114' zurückfließende Kraftstoff auf einen von der Leitungs-Einrichtung im KraftstoffbehälterAccording to the invention, the return line 114 ′ for the excess fuel opens tangentially into the outer annular space 105, in particular in the region of the opening 104. As a result, the fuel flowing back from the line 114 'is directed to one of the line devices in the fuel tank

mündung bis zur Öffnung 106 reichenden längeren Strömungsweg durch den Raum 105 gezwungen, auf welchem in den Kraftstoff gelangte Luftbläschen und Schaum Gelegenheit haben, aus der Kraftstoffflüssigkeit bereits auszuscheiden, ehe diese in den inneren Stauraum E gelangt. Da die in diesem Raum befindliche Kraftstoffmenge durch den zuströmenden Rücklaufkraftstoff nicht unmittelbar beunruhigt wird, wird auch im Stauraum E die weitere Entschäumung und Entgasung des Kraftstoffes begünstigt. Aus dem Raum E fließt der Kraftstoff durch das Filter 117 in den Ringkanal 122, von wo er durch die Leitung 113' abgesaugt wird. Im Ringkanal 122 werden die letzten Gasreste aus dem Kraftstoff ausgeschieden und durch das Filter 117 die letzten Schaumbläschen zurückgehalten. The longer flow path reaching the opening 106 is forced through the space 105 , on which air bubbles and foam that have entered the fuel have the opportunity to excrete from the fuel liquid before it reaches the inner storage space E. Since the amount of fuel in this space is not directly disturbed by the incoming return fuel, further defoaming and degassing of the fuel is also promoted in storage space E. From the space E , the fuel flows through the filter 117 into the annular channel 122, from where it is sucked off through the line 113 '. The last gas residues are separated from the fuel in the annular channel 122 and the last small foam bubbles are retained by the filter 117.
