Abstract

The filter element comprises a non-woven material containing metal and/or glass fibers. A zigzag folded strip is made from panels or rolled sheet. Individual surfaces are defined by pre-stamping (3, 4, 5, 6).

Description

Stand der Technik State of the art

Die Erfindung betrifft ein Filterelement, insbesondere zur Flüssigkeitsfilterung nach dem Oberbegriff des An spruchs 1. The invention relates to a filter element, in particular for filtering liquids according to the preamble of claim 1.

Es ist ein Filterelement beispielsweise aus der DE 94 03 868.6 U1 mit einer zick-zack-förmig gefalteten Filterbahn bekannt, bei dem die Filterbahn sternförmig zusammenge legt ist. There is a filter element, for example, from DE 94 03 868.6 U1 with a zigzag-shaped folded filter web, in which the filter web together quantitative star-shaped sets is. Der dadurch gebildete Hohlzylinder wird radial von außen von der zu filternden Flüssigkeit angeströmt und die gefilterte Flüssigkeit wird zentral aus dem Fil terelement herausgeleitet. The hollow cylinder formed thereby is radially flows from the outside of the liquid to be filtered and the filtered liquid is centrally passed out of the Fil terelement.

Das Material der Filterbahn ist bei dem bekannten Filter element Papier, Filz oder ein Kunststoffvlies, wobei die se Filterelemente als auswechselbarer Einsatz in ein ent sprechendes Filtergehäuse eingefügt werden. The material of the filter web in the known filter element of paper, felt or synthetic fleece, the se filter elements are inserted as exchangeable insert in a filter housing ent speaking. Nach einer bestimmten Betriebszeit weisen diese Filterelemente mit bekannten Filtermaterial keine ausreichende Filterei genschaft mehr auf und müssen ersetzt werden. After a certain time, these filter elements have known filter material sufficient Filterei genschaft more, and must be replaced.

Aufgabenstellung task

Der Erfindung liegt die Aufgabe zugrunde, ein Filterele ment der eingangs genannten Art so fortzubilden, daß bei einem beibehaltenem einfach Aufbau eine große Lebensdauer des Filterelements erreicht werden kann. The invention has the object of providing a Filterele ment of the type mentioned retrain so that a large element life can be achieved with a simple structure beibehaltenem.

Vorteile der Erfindung Advantages of the Invention

Das erfindungsgemäße Filterelement ist, insbesondere für die Anwendung als Flüssigkeitsfilter in einem Kraftfahr zeug, mit den Merkmalen des Kennzeichens des Anspruchs 1 dadurch vorteilhaft, daß mit einem Filtervlies, das Me tall- oder Glasfaser enthält, eine außerordentlich große Lebensdauer, gegebenenfalls sogar entsprechend der Le bensdauer des angeschlossenen Aggregats, ermöglicht wird. The filter element according to the invention, in particular for use as a fluid filter in a motor driving generating, with the features of the characterizing part of claim 1 is advantageous in that a filter fleece, tall oil which Me or contains glass fiber, an extremely long-life, possibly even according to the Le will service life of the connected unit, allows. Hierdurch wird auch die Konstruktion des Filtergehäuses vereinfacht, da eine Auswechslung des Filterelements nicht mehr notwendig ist. In this way, the construction of the filter housing is simplified, as a replacement of the filter element is no longer necessary.

Um nach wie vor einen Aufbau des Filterelements, vorzugs weise sternförmig mit Zick-Zack-Falten, in vorteilhafter Weise zu ermöglichen, ist die Filterbahn aus vorgeprägten Filtervliesplatten oder aus einer aufgerollten Filter vliesbahn hergestellt und anhand der Vorprägung werden die Einzelflächen der Zick-Zack-Form im Herstellungspro zeß herausgebildet. To still a construction of the filter element preference, as a star shape with a zig-zag pleats, to allow in an advantageous manner, the filter web of pre-embossed nonwoven filter plates or of a rolled filter is made nonwoven web and on the basis of pre-cut, the individual faces of the zig-zag form in Herstellungspro process emerged. Somit kann dauerhaft ein mechanisch stabiles Filterelement gebildet werden, das die Vorteile der relativ großen Filteroberfläche auch bei einer Stern faltung, bezogen auf den jeweiligen Bauraum, beibehält und damit nicht auf die, für sich gesehen bekannte Mehr lagenanordnung mit diversen Vliesmaterialien zurückge griffen wird. is attacked thus permanently mechanically stable filter element are formed, the folding advantage of the relatively large filter surface even with a star, based on the respective space, maintains and not, per se known to the multi-location arrangement with various nonwoven materials Retired.

Mit einer vorteilhaften Ausführungsform des Filtervlie ses, das vollständig aus Metallfasern besteht, können Filterbahnen von ca. 1 mm Dicke in verschiedenen Poren feinheiten und Faserdicken, insbesondere aus Edelstahlfa sern, hergestellt werden. With an advantageous embodiment of the Filtervlie ses, which is made entirely of metal fibers, filter webs of about 1 mm thickness can be prepared in various intricacies pores and fiber thicknesses, in particular fibers Edelstahlfa. Auch eine Verwendung von gesin tertem Metallfaservlies ist vorteilhaft. Also, a use of Gesin tertem metal fiber fleece is advantageous. Das Metallfa servlies eignet sich besonders zum Einsatz im thermisch beanspruchten Ölfilterbereich, wobei die Fasern eine aus reichende Kapazität aufweisen um die Schmutzpartikel über eine lange Lebensdauer zu speichern ohne zu verspröden. The Metallfa servlies is particularly suitable for use in thermally stressed oil filter region, wherein the fibers have a store from reaching capacity to have the dirt particles over a long lifetime without becoming brittle.

In einer Mischform kann gemäß einer weiteren Ausführungs form das Filtervlies mit unterschiedlichen Metallfaser durchmessern in einlagiger Ausführung für bestimmte Fil tervliesanordnungen gewichts- und preisgünstiger einge setzt werden. In a mixed form the filter fleece can, according to another execution form with different metal fiber diameters in a single-layer version for certain Fil tervliesanordnungen weight and inexpensive is set to be.

Bei einer anderen bevorzugten Ausführungsform des Filte relements als Glasfaservlies kann dieses in vorteilhafter Weise ein- oder beidseitig mit Polyesterfasern kaschiert bzw. beschichtet werden. In another preferred embodiment of the Filter relements as glass fiber fleece, this can be activated in an advantageous manner or on both sides with polyester fibers or coated. Hierdurch ist eine Rillierung oder sonstige Prägung auf einfache Weise durchführbar und das Glasfaservlies kann ohne zusätzliches Schutzvlies auf der An- oder der Abströmseite und gegebenenfalls auch oh ne Stützgewebe zu einem Sternfalt-Filterelement verarbei tet werden. This results in a grooving or other embossing can be carried out in a simple manner and the nonwoven glass fabric can be used without additional protective fleece on the presence or the downstream side, and optionally also oh ne support fabric to Sternfalt filter element proces tet be.

Eine gute Stabilität der Stern- bzw. Zick-Zack-Faltung ist auf einfache Weise erreichbar, wenn die Vorprägung aus quer zur Faltkante verlaufenden Rillungen oder son stigen Prägearten jeweils innerhalb einer Einzelfläche der Filterbahn besteht. A good stability of the star or zig-zag fold is achieved in a simple manner when the pre-embossing is made transverse to the folding creases or son Stigen embossing style in each case within a single area of ​​the filter web. Die Vorprägungen können jeweils auch entlang der gewünschten Faltkanten für eine einfache mechanische Verarbeitung des Rohmaterials der Filterbahn vorgesehen werden. The knockouts may each be provided along the desired folding lines for a simple mechanical processing of the raw material of the filter web.

Das erfindungsgemäße Filterelement der oben beschriebenen Ausführungsformen kann bevorzugt im Hydraulikbereich, im Schaltgetriebebereich, im Schmieröl- oder Kraftstoff filterbereich eines Kraftfahrzeuges oder auch bei der Was serfiltration oder bei der Filtrierung von aggressiven Medien eingesetzt werden. The filter element according to the invention of the above-described embodiments may preferably be in the field of hydraulics, in the manual range, the lubricating oil or fuel filter area of ​​a motor vehicle or even when What serfiltration or in the filtration of corrosive media are used. Es sind in der Regel bei einer geeigneten Faserdicke keine zusätzlichen Feinfilter not wendig. There are not agile usually at an appropriate fiber thickness no additional fine filter.
