Abstract

The proposed filter which can be introduced into a fuel container, has an elastic framework composed of a thermoplastic. The framework supports an elastic permeable plastic filter cloth. The filter further has a connection piece (2) for the fuel pump and for the fuel line. The connection piece (2) faces the fuel filler opening arranged on the container. The fuel enters from the exterior through the filter cloth into the interior of the filter and is passed on from there through the connection piece (2). The ratio of the height of the filter to its maximum width is 1:3 to 8. The connection piece (box 3) for the fuel line is arranged centrally and is firmly attached to the framework. The framework is composed of elastic, radially-running shoulders (5) and ribs (6) which are arranged in the central area of the filter and are firmly attached to the cloth and the elasticity of which increases from the centre of the filter body towards the filter rim. <IMAGE>

Description

Die Erfindung betrifft ein Filter nach dem Oberbegriff des Patent­ anspruchs 1.The invention relates to a filter according to the preamble of the patent claim 1.

Filter dieser Art müssen beim Zusammenbau des Kraftstoffsystems in den Kraftstoffbehälter hineingebracht werden. Die optimale Lage des Filters ist in unmittelbarer Nähe des Behälterbodens; es kann auch am Behälterboden aufliegen, ohne daß dessen Leistung beeinträchtigt wird. Das Austrittsende des Filters ist an einer Kraftstoffpumpe angeschlossen, über die der filtrierte Kraftstoff direkt oder über zwischengeschaltete Einrichtungen zu dem Vergaser oder den Einspritzelementen des Verbrennungsmotors geführt wird.Filters of this type must be used when assembling the fuel system be brought into the fuel tank. The optimal one The filter is in the immediate vicinity of the tank bottom; it can also rest on the bottom of the container without its performance is affected. The outlet end of the filter is at one Fuel pump connected through which the filtered fuel directly or via intermediary devices to the carburetor or the injection elements of the internal combustion engine.

Gegenwärtig werden s.g. "In-Tank-Pumpen" benutzt, die sich innerhalb des Behälters befinden und mit Gebern, Leitungen usw. für die Anzeigevorrichtungen versehen sind. Das Kraftstoff-Filter wird - in der Kraftstoff-Flußrichtung gesehen - vor der Pumpe geschaltet. Der Kraftstoffstrom fließt von außen durch das Filtergewebe, wobei feste, mit dem Strom geführte Teilchen am Gewebe getrennt werden.Currently so-called "In-tank pumps" are used, which are located within of the container and with sensors, lines, etc. for the Indicators are provided. The fuel filter will - seen in the direction of fuel flow - switched in front of the pump. The fuel flow flows from the outside through the filter cloth, whereby solid, current-carrying particles are separated on the tissue.

Das Einbringen des Filters samt Pumpe und Zubehör in den Kraftstoff­ behälter bringt erhebliche Probleme mit sich, insbesondere bei Be­ hältern aus Kunststoffen, bei denen eine verhältnismäßig grobe Toleranz in den Höhenmaßen gegeben ist. Beim Zusammenbau des Kraftstoffsystems muß das ganze Paket (Filter, Pumpe, Zubehör) in den Behälter durch das Füll-Loch mit einem begrenzten Durchmesser gesteckt werden. dabei muß das Filter, das größer als das Füll-Loch ist, verformt werden.The insertion of the filter together with the pump and accessories in the fuel container brings with it considerable problems, especially with Be plastic containers, which have a relatively coarse tolerance is given in the height dimensions. When assembling the fuel system the whole package (filter, pump, accessories) has to go through the container the filling hole with a limited diameter. the filter, which is larger than the filling hole, must be deformed will.

Bekannt sind Filter, die aus einem elastischen Rippengerüst beste­ hen, welches das Filtergewebe stützt (DT-OS 31 33 343). Filter dieser Art sind im beschränkten Maß verformbar, können jedoch bei der gegenwärtigen Technologie den Einbau nicht wesentlich erleichtern.Filters are known which best consist of an elastic rib structure which supports the filter fabric (DT-OS 31 33 343). Filters of this type are deformable to a limited extent, but cannot make installation much easier with current technology.

Man hat bereits versucht, starre Filter in gebogener Form (Stiefelform, Bohnenform usw.) zu verwenden. Diese Versuche blieben auch ohne Erfolg, weil solche Filter mit Pumpe und Zubehör entweder über­ haupt nicht oder nur mit großen Schwierigkeiten durch das Füll- Loch gesteckt werden konnten.Attempts have already been made to use rigid filters in a curved shape (boot shape,  Bean shape, etc.). These attempts were also without Success because such filters with pump and accessories either over not at all or only with great difficulty due to the filling Hole could be put.

Ungünstig verliefen auch Versuche mit teilweise verdrehbaren Kunst­ stoff-Filtern, die aus einem, sich über die ganze Filterfläche erstreckenden elastischen Gerüst bestehen, das mit dem Filter­ gewebe stoffschlüssig verbunden ist. Das Gerüst weist nämlich ein ganz anderes Schrumpfmaß auf, als das Gewebe und infolge der Umgebungsbedingungen (Temperatur, chemische Einflüsse usw.) traten an den Filtern bleibende Deformationen auf, die die Arbeit der Filter erheblich beeinträchtigten.Attempts with partially rotatable art were also unfavorable Fabric filters that consist of one, spread over the entire filter area extending elastic scaffold exist that with the filter fabric is cohesively connected. The scaffold points a completely different degree of shrinkage than the fabric and as a result the environmental conditions (temperature, chemical influences, etc.) there were permanent deformations on the filters that did the work the filter significantly affected.

Aufgabe der vorliegenden Erfindung ist es, ein Filter der eingangs genannten Art zu finden, das zwar ausreichend nachgiebig ist und während des Einbaus in den Behälter beim Durchstecken durch das Kraftstoff-Füll-Loch eine ausreichende Formveränderung anzunehmen vermag, nach dem Einbau jedoch sofort die ursprüngliche Form wieder erlangt und sie bleibend behält. Der Aufbau des Filters soll möglichst einfach sein.The object of the present invention is a filter of the beginning mentioned type to find, which is sufficiently compliant and during installation in the container when pushing through the Fuel fill hole to assume a sufficient shape change capable, but immediately after installation, the original shape regained and keeps them permanently. The structure of the filter should be as simple as possible.

Erfindungsgemäß wird diese Aufgabe durch die kennzeichnenden Merk­ male des Patentanspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.According to the invention, this object is achieved by the characterizing note male of claim 1 solved. Advantageous further training the invention emerge from the subclaims.

Das erfindungsgemäße Filter ist während des Durchsteckens durch die Kraftstoff-Füllöffnung im Behälter sehr leicht verformbar, insbesondere im Randbereich, nimmt aber innerhalb des Behälters seine Grundform sofort wieder an und behält sie bleibend.The filter according to the invention is through during insertion the fuel filling opening in the tank is very easily deformable, especially in the edge area, but takes within the container immediately resumes its basic form and retains it.

Durch die Umgebungsbedingungen verursachte geringe Formveränderungen beeinträchtigen die Funktion des Filters im vernachlässigbaren Maß, denn die aufgrund des unterschiedlichen Schrumpfmaßes des Gerippes und des Gewebes auftretenden Deformationen spielen sich - dank der erfindungsgemäßen Anordnung des Gerippes - praktisch nur in dem kleineren Mittelbereich des Filters ab, während der größere Randbereich deformationslos bleibt. Die Größe der offenen Filter­ fläche bleibt konstant. Die Grundfläche des Filters kann bei seiner flachen Form stets in Berührung mit dem Behälterboden bleiben.Small changes in shape caused by the ambient conditions impair the function of the filter to a negligible extent, because the deformations occurring due to the different shrinkage dimensions of the frame and the fabric - thanks to the arrangement of the frame according to the invention - practically only take place in the smaller central area of the filter during the larger edge area remains without deformation. The size of the open filter area remains constant. With its flat shape, the base of the filter can always remain in contact with the bottom of the container.

In den beigefügten Zeichnungen ist ein Ausführungsbeispiel des erfindungsgemäßen Filters dargestellt. In the accompanying drawings, an embodiment of the illustrated filter according to the invention.  

Es zeigen:Show it:

Fig. 1 ein erfindungsgemäßes Filter im Axialschnitt und Fig. 1 is an inventive filter in axial section and

Fig. 2 eine Draufsicht auf das Filter nach Fig. 1, wobei die linke Hälfte des Filter-Oberteils abgenommen ist. Fig. 2 is a plan view of the filter of FIG. 1, with the left half of the filter upper part removed.

Das Filter besteht aus zwei Hälften, nämlich aus dem kegelstumpf­ förmigen Oberteil 1 und dem kreisförmigen, leicht konvexen Unter­ teil 2. Am Oberteil ist eine profilierte Buchse 3 für den Pumpen­ anschluß vorgesehen. In die Buchse 3 wird ein nicht dargestellter Pumpenzapfen eingesteckt. An der Außenseite der Buchse 3, in ihrem oberen Bereich, ist eine Auskragung 4 angeformt. Mit der Buchse 3 ferner die Schultern 5 verbunden. Das gestanzte kegelförmige Filter­ teil 7 ist sowohl mit der Buchse 3 als auch mit den Schultern 5 fest verbunden.The filter consists of two halves, namely the frustoconical upper part 1 and the circular, slightly convex lower part 2 . At the top, a profiled socket 3 is provided for the pump connection. A pump plug (not shown) is inserted into the socket 3 . On the outside of the socket 3 , in its upper area, a projection 4 is formed. The shoulders 5 are also connected to the socket 3 . The punched conical filter part 7 is firmly connected to both the socket 3 and the shoulders 5 .

Der Unterteil 2 des Filters besteht aus einem kreisförmigen Gewebe­ teil 8 sowie einem Gerippe (im dargestellten Beispiel aus Poly­ amid) mit radial angeordneten Rippen 6.The lower part 2 of the filter consists of a circular fabric part 8 and a frame (in the example shown made of poly amide) with radially arranged ribs 6 .

Erfindungswesentlich ist, daß sowohl die Schultern 5 als auch die Rippen 6 sich zum Rand des Filters hin verjüngen, so daß in dem Randbereich des Filters das Schrumpfmaß des Gewebes und der Teile des Gerippes annähernd gleich ist.It is essential to the invention that both the shoulders 5 and the ribs 6 taper towards the edge of the filter, so that the shrinkage of the fabric and the parts of the frame are approximately the same in the edge region of the filter.

Die beiden Filterhälften (Oberteil 1 und Unterteil 2) sind durch Zusammenschweißen der Ränder miteinander fest verbunden.The two filter halves (upper part 1 and lower part 2 ) are firmly connected to one another by welding the edges together.

Beim Einbau des Filters kann der Filterkörper mit der angeschlossenen Pumpe sowie den anderen Einrichtungen (Geber, Zuleitungen, elektr. Leitungen usw.) im Randbereich praktisch unbeschränkt zusammenge­ drückt und durch die Einfüllöffnung in den Tank gesteckt werden. Das Filter nimmt dank seiner Anordnung sofort seine ursprüngli­ che Form wieder an und behält sie bleibend.When installing the filter, the filter body can be connected to the Pump as well as the other devices (sender, supply lines, electr. Lines etc.) in the edge area practically unlimited presses and inserted into the tank through the filler opening will. Thanks to its arrangement, the filter immediately returns to its original position form and retains it permanently.

In dem dargestellten Beispiel wird das Filter in einer Spritzform hergestellt. Der Gewebezuschnitt für den Oberteil 1 wird in die Form gelegt und die Buchse 3 sowie die Schultern 5 aufgespritzt. Ähnlich wird der Unterteil 2 hergestellt: Auf den Gewebezuschnitt (Gewebeteil 8) werden die Rippen 6 aufgespritzt.In the example shown, the filter is manufactured in an injection mold. The fabric blank for the upper part 1 is placed in the mold and the bushing 3 and the shoulders 5 are sprayed on. The lower part 2 is produced in a similar way: the ribs 6 are sprayed onto the fabric blank (fabric part 8 ).
