Feinfilter für eine KraftstofffördereinheitFine filter for a fuel delivery unit
Die Erfindung betrifft einen Feinfilter für eine Kraftstofffördereinheit eines Kraftfahrzeuges mit einem Filterelement, mit Mitteln zur Befestigung des Filterelementes an der Kraftstofffördereinheit und an einem die Kraftstofffördereinheit umgebenden Schwalltopf.The invention relates to a fine filter for a fuel delivery unit of a motor vehicle with a filter element, with means for fastening the filter element to the fuel delivery unit and to a swirl pot surrounding the fuel delivery unit.
Solche Feinfilter werden in heutigen Kraftfahrzeugen insbesondere bei zweistufigen Kraftstofffördereinheiten häufig eingesetzt und sind aus der Praxis bekannt. Die erste Stufe der Kraftstofffördereinheit fördert in der Regel Kraftstoff über einen Vorfilter aus einem Kraftstoffbehälter in den oberen Bereich des Schwalltopfes. Die zweite Stufe der Kraftstof fördereinheit fördert den Kraftstoff aus dem unteren Bereich des Schwalltopfes zu einer Brennkraftmaschine des Kraftfahrzeuges. Der Feinfilter wird dabei im mittleren Bereich des Schwalltopfes angeordnet und hat ein axial vom Kraftstoff durchströmtes Gehäuse mit dem darin angeordneten Filterelement. Nachteilig bei dem bekannten Feinfilter ist, dass er sehr aufwändig aufgebaut ist und einen großen Platzbedarf hat. Daher erfordert der Filter einen sehr großen Schwalltopf. Dies führt zu einem sehr kostenintensiven Aufbau des Schwalltopfes und des Feinfilters.Such fine filters are frequently used in today's motor vehicles, particularly in two-stage fuel delivery units, and are known from practice. The first stage of the fuel delivery unit generally delivers fuel from a fuel tank into the upper region of the swirl pot via a prefilter. The second stage of the fuel delivery unit delivers the fuel from the lower region of the baffle to an internal combustion engine of the motor vehicle. The fine filter is arranged in the middle region of the swirl pot and has an axially flowed through by the fuel housing with the filter element arranged therein. A disadvantage of the known fine filter is that it has a very complex structure and requires a large amount of space. The filter therefore requires a very large baffle. This leads to a very expensive construction of the surge pot and the fine filter.
Weiterhin ist aus der Praxis ein Feinfilter bekannt geworden, der die Kraftstofffördereinheit ringförmig umschließt und am Boden des Schwalltopfes befestigt wird. Dieser Feinfilter hat kleine Abmessungen, vermag den Kraftstoff jedoch nicht ausreichend und dauerhaft zu filtern. Um ein schnelles Zusetzen des Feinfilters mit
Schmutzpartikeln zu vermeiden, weist das Filterelement daher in der Regel eine Maschenweite von 40 - 80 μm auf.Furthermore, a fine filter has become known from practice, which surrounds the fuel delivery unit in a ring and is attached to the bottom of the swirl pot. This fine filter has small dimensions, but cannot filter the fuel sufficiently and permanently. To quickly clog the fine filter with To avoid dirt particles, the filter element usually has a mesh size of 40 - 80 μm.
Der Erfindung liegt das Problem zugrunde, einen Feinfilter der eingangs genannten Art so zu gestalten, dass er besonders kostengünstig herstellbar ist und den Einsatz von Filterelementen mit einer besonders kleinen Maschenweite ermöglicht.The invention is based on the problem of designing a fine filter of the type mentioned at the outset in such a way that it can be produced particularly cost-effectively and enables the use of filter elements with a particularly small mesh size.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass das Filterelement ringförmig gestaltet und jeweils zur Befestigung an Mantelflächen der Kraftstofffördereinheit und des Schwalltopfes vorgesehen ist und zumindest zwei im Wesentlichen axial ausgerichtete, konzentrisch zur Symmetrieachse angeordnete Abschnitte hat.This problem is solved according to the invention in that the filter element is designed in a ring shape and is provided in each case for attachment to lateral surfaces of the fuel delivery unit and the surge pot and has at least two essentially axially aligned sections arranged concentrically to the axis of symmetry.
Durch diese Gestaltung lässt sich das Filterelement unmittelbar an dem Schwalltopf und der Kraftstofffördereinheit befestigen. Daher erfordert der erfindungsgemäße Feinfilter kein kostenintensives und geräumiges Gehäuse. Der erfindungsgemäße Feinfilter lässt sich daher besonders kostengünstig fertigen. Die in axialer Richtung weisenden Abschnitte führen zu einer besonders großen Oberfläche des Filterelementes und daher zu einer besonders geringen Verstopfungsanfälligkeit. Ein weiterer Vorteil der Erfindung besteht darin, dass sich der erfindungsgemäße Feinfilter auch bei kleinen Abmessungen des Schwall- topfes und damit sehr engen Kraftstoffbehältern einsetzen lässt .With this design, the filter element can be attached directly to the swirl pot and the fuel delivery unit. Therefore, the fine filter according to the invention does not require an expensive and spacious housing. The fine filter according to the invention can therefore be manufactured particularly inexpensively. The sections pointing in the axial direction lead to a particularly large surface area of the filter element and therefore to a particularly low susceptibility to clogging. Another advantage of the invention is that the fine filter according to the invention can also be used with small dimensions of the surge pot and thus very narrow fuel tanks.
Zur weiteren Verringerung der Fertigungskosten des erfindungsgemäßen Feinfilters trägt es bei, wenn das Filterelement in einer axialen Schnittebene V-förmig gestaltet ist. Weiterhin hat der Feinfilter hierdurch eine hohe Stabilität.
Große Mengen der von dem Filterelement zurückgehaltenen Schmutzpartikel lassen sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung einfach in einem kleinen Teilbereich des Filterelementes sammeln, wenn das Filterelement in einer axialen Schnittebene im Wesentlichen U-förmig gestaltet ist.It contributes to a further reduction in the manufacturing costs of the fine filter according to the invention if the filter element is V-shaped in an axial sectional plane. Furthermore, the fine filter has a high stability. According to another advantageous development of the invention, large quantities of the dirt particles retained by the filter element can easily be collected in a small partial area of the filter element if the filter element is essentially U-shaped in an axial section plane.
Eine besonders große Oberfläche des Filterelementes bei besonders geringen Abmessungen lässt sich gemäß einer anderen vorteilhaften Weiterbildung der Erfindung erreichen, wenn die Abschnitte des Filterelementes hülsen- förmig gestaltet und konzentrisch um seine Symmetrieachse angeordnet sind und wenn jeweils zwei Abschnitte mittels eines ringscheibenfδrmigen Abschnittes miteinander verbunden sind.A particularly large surface area of the filter element with particularly small dimensions can be achieved according to another advantageous development of the invention if the sections of the filter element are sleeve-shaped and arranged concentrically around its axis of symmetry and if two sections are connected to one another by means of a ring-shaped section.
Zur weiteren Vergrößerung der Oberfläche des Filterelementes trägt es gemäß einer anderen vorteilhaften Weiterbildung der Erfindung bei, wenn mehrere Abschnitte einander konzentrisch umschließen.According to another advantageous development of the invention, the surface area of the filter element is further enlarged if a plurality of sections surround one another concentrically.
Der erfindungsgemäße Feinfilter gestaltet sich konstruktiv besonders einfach und lässt sich mit geringem Aufwand montieren, wenn das Filterelement aus einem Material oder mehreren Materiallagen mit einer vorgesehenen Stabilität gefertigt ist und an seinen Rändern Mittel zur Befestigung an dem Schwalltopf oder der Kraftstofffördereinheit hat.The fine filter according to the invention is structurally particularly simple and can be assembled with little effort if the filter element is made of one material or several layers of material with an intended stability and has means for attachment to the swirl pot or the fuel delivery unit at its edges.
Die Kraftstofffördereinheit wird gemäß einer anderen vorteilhaften Weiterbildung der Erfindung besonders zuverlässig vor Verschmutzung und damit vor Verschleiß geschützt, wenn das Filterelement eine Maschenweite von 15/xm hat. Dies führt im Gegensatz zu dem Filterelement des bekannten Feinfilters mit eine Maschenweite von 40 -
80 μm zu einer besonders feinen Filterung des Kraftstoffs .According to another advantageous development of the invention, the fuel delivery unit is protected particularly reliably against contamination and thus against wear if the filter element has a mesh size of 15 / xm. In contrast to the filter element of the known fine filter with a mesh size of 40 - 80 μm for a particularly fine filtering of the fuel.
