Abstract
Bekannte Vorrichtungen haben eine in einem Speicherbehälter angeordnete Saugstrahlpumpe, die Kraftstoff über eine Ansaugöffnung in einem Boden des Speicherbehälters aus einem Vorratsbehälter in den Speicherbehälter fördert. Der Ansaugöffnung ist ein Filtergewebe vorgeschaltet, das im Kraftstoff des Vorratsbehälters enthaltene Schmutzpartikel herausfiltert, damit diese nicht die Funktionsfähigkeit von der Ansaugöffnung nachgeschalteten Ventilen beeinträchtigen können. Nachteilig ist, dass das Filtergewebe bei stark verunreinigtem Kraftstoff zunehmend verstopft und dadurch einen ansteigenden Druckverlust erzeugt, so dass bei gleicher Leistung der Förderpumpe zunehmend weniger Kraftstoff in den Speicherbehälter gefördert wird. DOLLAR A Bei der erfindungsgemäßen Vorrichtung ist eine alternative Partikelabscheidung vorgesehen, die eine größere Aufnahmefähigkeit für Partikel als der Stand der Technik aufweist. DOLLAR A Erfindungsgemäß ist vorgesehen, an und/oder in dem Boden (23) des Speicherbehälters (2) auf der der Förderpumpe (16) zugewandten Innenseite (19) mehrere, zu dem Speicherbehälter (2) hin offene Kammern (24) zur Abscheidung von im Kraftstoff enthaltenen Schmutzpartikeln anzuordnen, wobei die Förderpumpe (16) derart angeordnet ist, dass der aus der Förderpumpe (16) austretende Kraftstoff die Kammern (24) überströmt.Known devices have arranged in a storage tank suction jet pump, which promotes fuel via a suction port in a bottom of the storage container from a reservoir into the storage container. The intake opening is preceded by a filter fabric which filters out the dirt contained in the fuel of the reservoir, so that they can not affect the functioning of downstream of the intake valves. The disadvantage is that the filter fabric increasingly clogged with heavily contaminated fuel and thus generates an increasing pressure loss, so that with the same power of the feed pump increasingly less fuel is conveyed into the storage tank. DOLLAR A In the apparatus according to the invention an alternative particle separation is provided, which has a greater absorption capacity for particles than the prior art. DOLLAR A According to the invention, provided on and / or in the bottom (23) of the storage container (2) on the inside of the pump (16) facing the inside (19), to the storage container (2) open towards chambers (24) for the deposition of To arrange dirt particles contained in the fuel, wherein the feed pump (16) is arranged such that the fuel exiting from the feed pump (16) overflows the chambers (24).
Description
Die
Erfindung geht aus von einer Vorrichtung nach der Gattung des Hauptanspruchs.
Es ist schon eine Vorrichtung zum Fördern von Kraftstoff aus der
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Vorrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, daß auf einfache Art und Weise eine alternative Abscheidung der Schmutzpartikel aus dem Kraftstoff des Vorratsbehälters vorgesehen ist, indem an und/oder in dem Boden des Speicherbehälters auf einer der Förderpumpe zugewandten Innenseite mehrere, zu dem Speicherbehälter hin offene Kammern zur Abscheidung von im Kraftstoff enthaltenen Schmutzpartikeln vorgesehen sind, wobei die Förderpumpe derart angeordnet ist, dass der aus der Förderpumpe austretende Kraftstoff die Kammern überströmt.The inventive device with the characterizing features of the main claim has the Advantage that on simple way an alternative separation of the dirt particles from the fuel of the reservoir is provided by at and / or in the bottom of the storage container facing on one of the feed pump Inside several, to the storage container open towards the chambers Deposition of dirt particles contained in the fuel are provided, being the feed pump is arranged such that the fuel exiting from the feed pump the chambers overflowed.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Vorrichtung möglich.By in the subclaims listed activities are advantageous developments and improvements in the main claim specified device possible.
Besonders vorteilhaft ist, wenn die Kammern in Strömungsrichtung des aus der Förderpumpe austretenden Kraftstoffs hintereinander angeordnet sind, da auf diese Weise die Partikel besonders gut in den Kammern abgeschieden werden.Especially is advantageous if the chambers in the flow direction of the feed pump leaking fuel are arranged one behind the other, since on this way the particles are deposited particularly well in the chambers become.
Weiterhin vorteilhaft ist, wenn zusätzlich Kammern in Strömungsrichtung des aus der Förderpumpe austretenden Kraftstoffs gesehen nebeneinander angeordnet sind, da auf diese Weise die Abscheidewirkung noch weiter verbessert wird.Farther is advantageous if additional chambers in the flow direction from the feed pump emerging fuel are arranged side by side, because in this way the separation effect is further improved.
Sehr vorteilhaft ist, wenn die Kammern durch vom Boden des Speicherbehälters vorstehende Wandungen gebildet sind, da diese Ausführung besonders einfach und kostengünstig durch Spritzgießen herstellbar ist.Very is advantageous if the chambers by projecting from the bottom of the storage container walls are formed, since this execution particularly easy and inexpensive by injection molding can be produced.
Desweiteren vorteilhaft ist, wenn die Kammern durch zumindest zwei Führungswandungen gebildet sind, die durch mehrere quer zur Strömungsrichtung verlaufende Trennwandungen miteinander verbunden sind, da sich diese Ausführung besonders einfach und kostengünstig durch Spritzgießen herstellen lässt.Furthermore is advantageous if the chambers through at least two guide walls are formed by a plurality of transverse to the flow direction separating walls connected to each other, as this design is particularly simple and economical by injection molding can be produced.
Darüber hinaus vorteilhaft ist, wenn der Speicherbehälter eine der Führungswandungen bildet, da auf diese Weise gewährleistet ist, dass nahezu der gesamte aus dem Vorratsbehälter angesaugte Kraftstoff über die Kammern hinwegströmt und von Schmutzpartikeln gereinigt wird.Furthermore is advantageous if the storage container one of the guide walls forms as guaranteed in this way is that almost all of the fuel sucked from the reservoir over the Chambers flows away and is cleaned of dirt particles.
Vorteilhaft ist, wenn die in axialer Richtung des Speicherbehälters gemessene Höhe der Führungswandungen und/oder der Trennwandungen in Strömungsrichtung des aus der Förderpumpe austretenden Kraftstoffs zunimmt, da auf diese Weise die Abscheidewirkung verbessert wird.Advantageous is when measured in the axial direction of the storage container height of guide walls and / or the dividing walls in the flow direction of the feed pump escaping fuel increases, since in this way the separation effect is improved.
Nach einer vorteilhaften Ausgestaltung ist das Förderaggregat eine Saugstrahlpumpe.To In an advantageous embodiment, the delivery unit is a suction jet pump.
Außerdem vorteilhaft ist, wenn das Förderaggregat derart angeordnet ist, dass der aus einem Auslass des Förderaggregates in den Speicherbehälter austretende Kraftstoffstrahl schräg auf eine Umfangswandung des Speicherbehälters trifft, da der Kraftstoffstrahl auf diese Weise nicht zerteilt wird, sondern sich an die Umfangswandung anschmiegt und an dieser entlang strömt. Dadurch strömt nahezu die gesamte angesaugte Kraftstoffmenge über die Kammern hinweg, so dass eine ausreichende Reinigung des angesaugten Kraftstoffs gewährleistet ist.In addition, advantageous is when the delivery unit is arranged such that the from an outlet of the delivery unit in the storage tank emerging fuel jet obliquely on a peripheral wall of the storage container meets, because the fuel jet is not divided in this way, but conforms to the peripheral wall and flows along it. Thereby flows almost the entire amount of fuel sucked across the chambers, so that ensures sufficient cleaning of the sucked fuel is.
