Abstract

The filter unit may be an elongated cylinder with a diameter of 35 mm and an overall length of 140 mm. There are two concentric filter elements inside the outer casing of the filter. The fuel, especially oil, flows radially inward. The outer, annular filter element (1) consists of a fine filter of plastics foam which can filter out coarse and even fine solid contaminant particles. The inner filter element (2) may have an outer diameter of 15 mm and is of a water-absorbing polymer.

Description

Die Erfindung betrifft einen Vollstromfilter für die Absorption von Wasser aus Kraftstoffen. Handels­ übliche Kraftstoffilter sind in der Lage Grob- bzw. Feinpartikel aus Kraftstoffen zu filtern. Sie sind jedoch nicht in der Lage Wasser aus den Kraftstoffen zu absorbieren.The invention relates to a full flow filter for the absorption of water from fuels. Commercial Common fuel filters are able to filter coarse or fine particles from fuels. they are however unable to absorb water from the fuels.

Wasser sammelt sich beim Befüllen, oder durch Kondensationsvorgänge im Tank und auch im Kraft­ stoff an. Dies ist ein höchst schädlicher und somit unerwünschter Vorgang, von dem eine Gefahr für den Tank durch Korrosion ausgeht. Das Wasser kann aber auch zur Zerstörung der Einspritzanlagen durch Kavitation führen. Dadurch kann die Betriebssicherheit und Lebensdauer des Gerätes erheblich beeinträchtigt werden.Water collects when filling, or through condensation in the tank and also in power fabric. This is a highly harmful and therefore undesirable process that is dangerous for corrosion of the tank. The water can also destroy the injection systems lead through cavitation. This can significantly increase the operational safety and lifespan of the device be affected.

Es ist deshalb im hohen Maße erwünscht und erforderlich, die Kraftstoffe weitestgehend wasserfrei zu halten. Dies wird mit der vorliegenden Erfindung dadurch gelöst, daß der Kraftstoffilter ein in ihn eingebettetes wasserabsorbierendes Polymer enthält, das ein Vielfaches seines Volumens an Wasser aufnehmen kann. Die Polymere quellen durch die Wasseraufnahme auf, werden aber in dem Kraft­ stoffilter eingebunden und halten das Wasser aus dem Kraftstoffkreislauf zurück.It is therefore highly desirable and necessary for the fuels to be largely water-free hold. This is achieved with the present invention in that the fuel filter is in it embedded water-absorbing polymer that contains a multiple of its volume of water can record. The polymers swell up due to the water absorption, but become effective in the integrated and keep the water out of the fuel circuit.

Als wasserabsorbierende Polymere werden handelsüblich sogenannte Superabsorber verwendet, oder auch Super-Slurper genannt. Die Polymere sind synthetische Polymere wie vernetzte Polyacryl- Säure-Salze, oder Salze von Co-Polymeren aus Acrylamid und Acrylsäure. Weiterhin kommen Propf-Co-Polymere auf Basis von natürlichen Kohlenhydraten wie Stärke mit Acrylnitirl zum Einsatz.So-called superabsorbers are commercially used as water-absorbing polymers, or also called super slurper. The polymers are synthetic polymers such as cross-linked polyacrylic Acid salts, or salts of copolymers of acrylamide and acrylic acid. Graft copolymers also come based on natural carbohydrates such as starch with acrylic nylon.

Die Superabsorber werden in Granulatform, oder in Vlies bzw. Gewebeeingebettet in den Kraftstoffilter eingelegt.The superabsorbents are embedded in granules, or in fleece or tissue in the Fuel filter inserted.

Erfindungsgemäß werden die Kraftstoffilter wie beispielhaft auf der Zeichnung dargestellt, aufgebaut: Der Kunststoffschaumfilter Pos. 1 dient als Feinfilter zum Rückhalt der Grobpartikel. Das innenlie­ gende Granulat ist als wasserabsorbierendes Polymer Pos. 2 ausgebildet, zum Rückhalt des Wassers.According to the invention, the fuel filters are constructed as shown by way of example on the drawing: The plastic foam filter item 1 serves as a fine filter for retaining the coarse particles. The interior lying granulate is designed as a water-absorbing polymer pos. 2 , to retain the water.

Das Gehäuse des Kraftstoffilters ist hier nicht dargestellt, da dieses unterschiedliche Formen an­ nehmen kann und für die Erfindung nicht relevant ist. Das Öl strömt radial in das Filter ein, tritt durch die Filterschicht, wird auf der Innenseite durch das Polymer geleitet und nach oben abgezogen.The housing of the fuel filter is not shown here, since it takes on different shapes can take and is not relevant to the invention. The oil flows radially into the filter and passes through the filter layer is passed through the polymer on the inside and pulled upwards.

Der aufgepreßte Deckel Pos. 3 ist als 2. Filter ausgebildet und dient als Begrenzung der Polymerausdehnung.The pressed-on cover item 3 is designed as a second filter and serves to limit the polymer expansion.

Die Geometrien der Zeichnung sind beispielhaft und stellen eine mögliche Ausführungsform dar. An­ dere Ausführungsformen sind erfindungsgemäß möglich.The geometries of the drawing are exemplary and represent a possible embodiment their embodiments are possible according to the invention.

In der dargestellten Ausführungsform und den entsprechenden Volumina hat der Kunststoffschaum­ filter eine innenliegende Sauglage mit einer Absorptionsfähigkeit von 22.000 g/m², einem Filterge­ häuse von 25 mm Innendurchmesser mit einer dargestellten Länge von 150 mm und einem Leervo­ lumen von ca. 0,1 l eine Wasserabsorptionskapazität von ca. 50 ml.In the embodiment shown and the corresponding volumes, the plastic foam filter an internal suction layer with an absorption capacity of 22,000 g / m², a filter housing with an inside diameter of 25 mm, a length of 150 mm and an empty space lumen of approx. 0.1 l a water absorption capacity of approx. 50 ml.
