Abstract

On a filter cartridge (1) of star-shaped folded filter paper (2), baffle components (6, 7) are post-connected to attached end plates (4, 5) in order to reinforce the separation of water from the diesel fuel flowing through the filter, which baffle components permit a further coalescence of the finest water droplets already formed by the filter paper on the inside of the filter. <IMAGE>

Description

Das Rohrstück 7 weist einen auf einer Spirale verlaufenden Steg 8 auf und ist mit Hilfe des Klebers 3 in den Endscheiben 4 und 5 fest angebunden. Das Rohrstück 7 ist über den größten Teil seiner axialen Höhe undurchlässig und weist nur in seinem oberen der Endscheibe 4 zugewandten Bereich radiale Öffnungen 9 auf. Der Rohreinsatz 6 liegt fest an den Spiral-Stegen 8 des Rohrstückes 7 an. Zum leichten Einführen des Rohreinsatzes 6 in das Rohrstück 7 ist der Rohreinsatz 6 konisch ausgebildet. Im übrigen ist der Rohreinsatz 6 wie das Rohrstück 7 durch den Kleber 3 fest mit der Endscheibe 4 verbunden. Der Rohreinsatz 6 weist an seinem um die untere Endscheibe verlaufenden Flansch Spiralstege 10 auf, die die von den Stegen 8 gebildeten Kanäle nach radial außen fortführen. Durch die Stege 8 und 10 werden jeweils geschlossene Strömungskanäle 11 bzw. 12 geschaffen. Durch die beschriebene Formgebung der Schikaneeinbauteile wird der Kraftstoff in einer zur Wasserabscheidung äußerst günstigen Weise strömungsmäßig umgelegt Die Spiralstege sorgen insbesondere dafür, daß lange Kontaktwege zu dem strömenden Medium bestehen, um so die Koalierungszeit zu verlängern. Dadurch wird gleichzeitig ein sicheres Dekantieren des Wassers auf der Filterreinseite bewirkt. Darüber hinaus bewirken die Schikaneeinbauteile auch noch eine Erhöhung der Filterpatronen-Stabilität.The pipe section 7 has a web 8 running on a spiral and is firmly attached to the end disks 4 and 5 with the aid of the adhesive 3. The pipe section 7 is impermeable and over most of its axial height has radial openings only in its upper region facing the end disk 4 9 on. The pipe insert 6 rests firmly against the spiral webs 8 of the pipe section 7. The pipe insert is used for easy insertion of the pipe insert 6 into the pipe section 7 6 conical. Otherwise, the pipe insert 6, like the pipe section 7, is through the adhesive 3 is firmly connected to the end disk 4. The pipe insert 6 has on his around the lower end plate extending flange on spiral webs 10, which are of the Web 8 channels formed continue radially outward. Through the webs 8 and 10 each closed flow channels 11 and 12 are created. Through the described Shaping the chicane built-in parts, the fuel is used to separate water extremely favorable flow-related way. The spiral webs are particularly important for the fact that there are long contact paths to the flowing medium, and so does the coalescence time to extend. This means that the water can be safely decanted at the same time the filter clean side causes. In addition, the chicane fittings also effect an increase in the stability of the filter cartridge.

Claims (1)

Patentanspruch: Filterpatrone (1), bestehend aus sternförmig gefaltetem Filterpapier (2) mit angebundenen Endscheiben (4, 5) aus stabilerem Material für ein Diesel-Kraftstoffilter, das von außen nach innen durchströmt wird und Schikaneeinbauten zur Strömungsumlenkung des Kraftstoffes zur Wasserabscheidung aufweist, dadurch gekennzeichn e t, daß die Schikaneeinbauten bestehen aus einem mit Abstand in das Innere der Filterpatrone (1) eingebrachten mit der oberen Endscheibe (4) fest verbundenen und mit einem Flansch um die untere Endscheibe (5) herumlaufenden Rohreinsatz (6) sowie einem an dem inneren Umfang der Falten des Filterpapiers (2) anliegenden mit den Endscheiben (4, 5) fest verbundenem Rohrstück (7), das nur im Bereich der oberen Endscheibe (4) radial durchlässig ist, wobei in dem Ringraum zwischen dem Rohreinsatz (6) und dem Rohrstück (7) spiralförmig verlaufende an dem Rohrstück (7) angeformte Stege (8) geschlossene Strömungskanäle (11) bilden, die unter der unteren Endscheibe (5) in ebenfalls spiralförmige Kanäle (12) münden, die von an dem Flansch des Rohreinsatzes (6) angeformten Stegen (10) zwischen der Endscheibe (5) und dem Flansch des Rohreinsatzes (6) gebildet werden. Claim: filter cartridge (1), consisting of a star-shaped folded Filter paper (2) with attached end plates (4, 5) made of more stable material for a diesel fuel filter, which is flown through from the outside to the inside, and chicane fittings for deflecting the flow of the fuel for water separation, thereby marked that the chicane fittings consist of a spaced in the Inside of the filter cartridge (1) inserted with the upper end plate (4) firmly connected and pipe insert (6) running around the lower end plate (5) with a flange as well as one resting against the inner circumference of the folds of the filter paper (2) the end plates (4, 5) firmly connected pipe section (7), which is only in the area of the upper End plate (4) is radially permeable, in the annular space between the pipe insert (6) and the pipe section (7) extending in a spiral shape on the pipe section (7) Web (8) form closed flow channels (11) which are located under the lower end plate (5) also open into spiral channels (12), which are connected to the flange of the pipe insert (6) molded webs (10) between the end plate (5) and the flange of the pipe insert (6) can be formed. Die Erfindung betrifft eine Filterpatrone nach dem Oberbegriff des Patentanspruchs. The invention relates to a filter cartridge according to the preamble of Claim. Ein solches Filter ist aus US-Z.: DIESEL & GASTUR-BINE PROGRESS, Januar 1980, Seite 27 bekannt Dieses hat jedoch einen recht komplizierten Aufbau. Such a filter is from US-Z .: DIESEL & GASTUR-BINE PROGRESS, January 1980, page 27 known. However, this has a very complicated structure. Die Wasserabscheidung erfolgt dort in vor der eigentlichen Filterpatrone angeordneten Schikaneeinbauten. In diesen Schikaneeinbauten wird die zu filternde Flüssigkeit nicht nur umgelenkt, sondern sie wird zusätzlich auch noch durch relativ großvolumige Entspannungsräume geleitet Hiervon ausgehend, liegt der Erfindung die Aufgabe zugrunde, die Schikaneeinbauten raumsparender auszugestalten und gleichzeitig durch geschickte Zuordnung zu der Filterpatrone eine gute Wasserabscheidung zu erzielen. Im übrigen sollen die Schikaneeinbauten so in die Filterpatrone integriert werden, daß sie zusätzlich als Stützteil für die sternförmig gefaltete Papiereinlage der Filterpatrone dienen Gelöst wird diese Aufgabe durch eine Ausbildung der Filterpatrone nach den kennzeichnenden Merkmalen des Patentanspruchs.The water is separated there in front of the actual filter cartridge arranged chicane fixtures. In these chicane fixtures, the Fluid is not only diverted, but also becomes relative large-volume relaxation rooms based on this, the invention is the The underlying task is to design the chicane fixtures in a space-saving manner and at the same time a good water separation through clever assignment to the filter cartridge achieve. In addition, the baffle fittings should be integrated into the filter cartridge in such a way that that they are also used as a support for the star-shaped folded paper insert Filter cartridge serve This task is achieved by designing the filter cartridge according to the characterizing features of the claim. Ein Ausführungsbeispiel ist in der Zeichnung dargestellt, die eine in ein Wegwerfgehäuse eingesetzte Filterpatrone im Schnitt zeigt. An embodiment is shown in the drawing, which is a shows a filter cartridge inserted in a disposable housing in section. Die Filterpatrone 1 ist in einem Wegwerfgehäuse montiert. Die Filterpatrone 1 setzt sich zusammen aus dem sternförmig gefalteten Filterpapier 2, das mit Hilfe eines Klebemittels 3 an Endscheiben 4 (obere Endscheibe) und 5 (untere Endscheibe) fest angebunden ist. Die Schikaneeinbauten für die Umlenkung des Kraftstoffes zur verstärkten Wasserabscheidung bestehen aus einem Rohreinsatz 6 sowie einem Rohrstück 7. The filter cartridge 1 is mounted in a disposable housing. The filter cartridge 1 is composed of the star-shaped folded filter paper 2, which with the help an adhesive 3 on end plates 4 (upper end plate) and 5 (lower end plate) is firmly attached. The chicane fittings for the diversion of the fuel to the reinforced water separation consist of a pipe insert 6 and a pipe section 7th
