Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Filtereinrichtung insbesondere einen Flüssigkeitsfilter, insbesondere einen Kraftstofffilter oder Ölfilter für Brennkraftmaschinen.The invention relates to a filter device, in particular a liquid filter, in particular a fuel filter or oil filter for internal combustion engines.

Stand der TechnikState of the art

Aus der EP1035902 A1 sind Filtermedien bekannt, die mit ihren Meltblownschichten grundsätzlich einer Verschweißung zugänglich sind.From the EP1035902 A1 Filter media are known, which are basically accessible with their meltblown layers a weld.

Aus der EP1194204 ist der Ringschluss eines zickzackförmig gefalteten Filtermediums mittels eines Ultraschallschweißprozesses bekannt. Bei dem Schweißprozess wird ein Klip eingesetzt, um die beiden Enden eines Filtermediums zu verbinden.From the EP1194204 the ring closure of a zigzag folded filter medium by means of an ultrasonic welding process is known. In the welding process, a clip is used to connect the two ends of a filter medium.

Aufgabe der ErfindungObject of the invention

Der Erfindung liegt die Aufgabe zugrunde, eine einfachere und/oder kostengünstigere und/oder leichter herstellbare Verbindung der Enden eines Filtermediums zu einem Ringschluss, wie er z. B. für ein sterngefaltetes Filterelement, das aus eine zickzackfömig gefalteten Bahn umfasst, notwendig ist.The invention has for its object to provide a simpler and / or less expensive and / or easier to produce connection of the ends of a filter medium to a ring closure, as he z. B. for a star-folded filter element, which comprises a zigzagged folded web, is necessary.

Offenbarung der ErfindungDisclosure of the invention

Erfindungsgemäß wird diese Aufgabe durch ein Filterelement (1) umfassend einen zickzackfömig gefalteten Faltenbalg (2), wobei Enden (3, 4) des Faltenbalgs durch direktes Ultraschallverschweißen des Faltenbalgs verbunden sind, gelöst.According to the invention this object is achieved by a filter element ( 1 ) comprising a zigzag folded bellows ( 2 ), where ends ( 3 . 4 ) of the bellows are connected by direct ultrasonic welding of the bellows, solved.

Dabei können bei dem Filterelement zwei nach innen gerichtete Halbfalten miteinander verschweißt sein oder zwei nach außen gerichtete Halbfalten miteinander verschweißt sein.In this case, two inwardly directed half-folds can be welded together or two outwardly directed half-folds can be welded together in the filter element.

Es können auch zwei Halbfalten derart miteinander verschweißt sein, dass im Verbindungsbereich der zickzackförmige Faltenverlauf des Filterelements durch einen trapezförmigen Verlauf ersetzt ist.It is also possible for two half-folds to be welded together in such a way that the zigzag-shaped fold course of the filter element is replaced by a trapezoidal shape in the connection region.

Vorteilhafterweise setzt man für die Ultraschallverschweißung ein Medium mit hohem Kunststoffanteil und/oder einer Kunststofflage ein. Hierdurch muss für das Ultraschallverscheißen kein zusätzliches Material hinzugefügt werden, sodass das die Enden des Filtermediums direkt miteinander verschweißt werden können. Ein solches Medium ist z. B. in der EP 1035902 A1 beschrieben, deren Inhalt hiermit in die vorliegende Anmeldung aufgenommen wird.Advantageously, a medium with a high plastic content and / or a plastic layer is used for ultrasonic welding. As a result, no additional material must be added for the ultrasonic shedding, so that the ends of the filter medium can be welded directly to each other. Such a medium is z. B. in the EP 1035902 A1 described, the contents of which are hereby incorporated into the present application.

Offenbart ist hiermit auch ein Verfahren zur Herstellung eines Filterelements, insbesondere eines sterngefalteten Filterelements, wobei der Faltenbalg des Filterelements mit Ultraschall verschweißt wird.Disclosed is also a method for producing a filter element, in particular a star-folded filter element, wherein the bellows of the filter element is welded with ultrasound.

Die Verschweißung kann flächig, punktförmig oder linienförmig, mit und ohne Einprägungen erfolgen.The welding can be flat, punctiform or linear, with and without impressions.

Kurze Beschreibung der ZeichnungenBrief description of the drawings

Ausführungsbeispiele des erfindungsgemäßen Filterelements werden anhand der Figuren der Zeichnung näher erläutert. Es zeigen:Embodiments of the filter element according to the invention will be explained in more detail with reference to the figures of the drawing. Show it:

1 eine perspektivische Darstellung eines Filterelements 1 a perspective view of a filter element

2 den Querschnitt durch ein Filterelement, wie in 1 mit zwei Beispielen A und B für eine Verbindung des zickzackförmig gefalteten Mediums. 2 the cross section through a filter element, as in 1 with two examples A and B for a compound of the zigzag folded medium.

3 einen weiteren Querschnitt durch ein Filterelement, wie in 1 mit einem dritten Beispiel C für eine Verbindung des zickzackförmig gefalteten Mediums. 3 a further cross section through a filter element, as in 1 with a third example C for a compound of the zigzag-folded medium.

Ausführungsform(en) der ErfindungEmbodiment (s) of the invention

Gleiche Teile sind in den nachstehenden Figuren mit identischen Bezugszeichen bezeichnetLike parts are designated in the following figures with identical reference numerals

Die Darstellung gemäß 1 ist ein aus dem Stand der Technik bekanntes, sogenanntes sterngefaltetes Filterelement. Hierbei ist eine zickzackförmig gefaltete Filtermedienbahn, der Balg, zu einem Ring geschlossen. Auf den Beiden Seitenflächen (5, 6) können offene und/oder geschlossene Endscheiben an dem Filterelement angebracht sein.The representation according to 1 is a known from the prior art, so-called star-folded filter element. Here is a zigzag folded filter media web, the bellows, closed to form a ring. On the two side surfaces ( 5 . 6 ) open and / or closed end discs may be attached to the filter element.

2 zeigt den Querschnitt durch ein Filterelement, wie in 1 mit zwei Beispielen A und B für eine Verbindung des zickzackförmig gefalteten Mediums. 2 shows the cross section through a filter element, as in 1 with two examples A and B for a compound of the zigzag folded medium.

Bei A sind zwei Enden, im Beispiel Halbfalten, die nach innen in das Filterelement gerichtet sind miteinander verschweißt. Die Verschweißung muss hierbei nicht vollflächig vorhanden sein.In A, two ends, in the example half-folds directed inwardly into the filter element, are welded together. The welding does not have to be complete.

Bei C ist die Verschweißung zweier Halbfalten angedeutet, die nach außen gerichtet sind.At C, the welding of two half-folds is indicated, which are directed to the outside.

In Figur drei ist eine weitere Variante mit einem dritten Beispiel C für eine Verbindung des zickzackförmig gefalteten Mediums gezeigt. Zwei Enden, beispielsweise Halbfalten, sind hierbei so verschweißt, dass ein trapezförmiger Verlauf des Faltenbalges im Querschnitt entsteht.FIG. 3 shows a further variant with a third example C for a connection of the zigzag-folded medium. Two ends, for example, half-folds, are in this case welded so that a trapezoidal course of the bellows is formed in cross section.
