Abstract

The fluid filter is particularly for engine lubricating oil, having a detachable filter housing containing one or more annular filter elements, together with seals, bypass and/or non-return valves etc.. Only the filter element(7) is interchangeable. There can be a common supporting member(12) in the housing and from which the elements are detachable, and it can be of plastic and in several sections(12a,12b). The element itself can be of one material, typically paper, and with sleeves(10) of stiffened paper at the ends. Alternatively cotton-wool can be used, and a heat-exchanger can be incorporated in the housing.

Description

Die Erfindung betrifft ein ringförmiges radial durch­ strömbares Filterelement aus sternförmig gefaltetem flachem Material zum austauschbaren Einsatz in ein teilbares Filtergehäuse.The invention relates to an annular radial flowable filter element made of star-folded flat material for interchangeable use in one divisible filter housing.

Derartige Filterelemente sollen möglichst einfach aufgebaut sein, damit bei Erschöpfung des Filtermate­ rials möglichst wenig Material ausgetauscht und ent­ sorgt bzw. wiederaufgearbeitet werden muß. Gedacht ist dabei an Filterelemente, bei denen das Material nach Erschöpfung nicht reinigbar ist, d. h. die entwe­ der als ganzes entsorgt oder bei Wiederaufbereitung zerstört werden müssen.Such filter elements should be as simple as possible be built up so that when the filter mat is exhausted rials exchanged and removed as little material as possible worries or must be refurbished. I thought is on filter elements where the material cannot be cleaned after exhaustion, d. H. the eve which is disposed of as a whole or during reprocessing must be destroyed.

Die vorgenannten Anforderungen werden erfindungsgemäß mit einem ringförmigen Filterelement nach den Merkma­ len des Anspruchs 1 erfüllt.The above requirements are according to the invention with an annular filter element according to the Merkma len of claim 1 fulfilled.

Besonders vorteilhaft bei einer solchen Ausgestaltung ist es, daß das austauschbare Filterelement lediglich die für die Filtration unbedingt notwendigen Teile aufweist, die zudem noch aus gleichartigem Material bestehen, wodurch eine einfache Entsorgbarkeit gege­ ben ist. Particularly advantageous in such an embodiment is that the replaceable filter element is only the parts absolutely necessary for the filtration has, which also made of the same material exist, making it easy to dispose of ben is.  

Zweckmäßige Ausgestaltungen sind Gegenstand der Un­ teransprüche.Appropriate configurations are the subject of the Un claims.

Ausführungsbeispiele sind in der Zeichnung schema­ tisch dargestellt.Exemplary embodiments are shown in the drawing represented table.

In einem teilbaren Filtergehäuse 1 ist ein austausch­ bares Ring-Filterelement 2 eingesetzt.In a separable filter housing 1 , an exchangeable ring filter element 2 is used.

Das Filterelement 2 besteht aus sternförmig gefalte­ tem Filterpapier, das zu axial verlaufenden stirnsei­ tig dichten Falttaschen 3 verarbeitet ist. Zur Erzie­ lung der an den axialen Stirnenden dichten Taschen 3 ist das Filterpapier dort mit einem Kleber 4 mitein­ ander verbunden.The filter element 2 consists of star-shaped folded filter paper, which is processed to axially extending stirnsei tig folded pockets 3 . To educate the dense at the axial ends of the pockets 3 , the filter paper is there mitein with another 4 mitein connected.

An den stirnseitigen Enden der axialen Öffnung des Filterelementes 2 sind kurze Rohre 5 aus Pappe in das Filterelement eingeklebt. Die Verklebung sorgt für einen dichten Abschluß zwischen den Rohren 5 und dem stirnseitig zu Taschen geformten Filterpapier. Sämt­ liche Teile des Filterelementes 2 sind aus Papier. Lediglich der zur Verbindung dieser Teile erforderli­ che Kleber ist aus unterschiedlichem Material. Der Anteil des Klebers an dem gesamten Filterelement ist jedoch verschwindend gering. Bei Verwendung an­ schmelzbaren Materials für die einzelnen Teile des Filterelementes kann ein zusätzlicher Kleber auch ganz entfallen, so daß tatsächlich ausnahmslos gleichartiges Material für das Filterelement 2 be­ nutzt werden kann. Wie bereits eingangs erwähnt, er­ möglicht ein Filterelement aus ausschließlich gleich­ artigem Material eine recht einfache und kostengün­ stige Entsorgung bzw. Wiederaufbereitung. Short cardboard tubes 5 are glued into the filter element at the front ends of the axial opening of the filter element 2 . The adhesive ensures a tight seal between the tubes 5 and the filter paper formed on the end face into pockets. All parts of the filter element 2 are made of paper. Only the adhesive required to connect these parts is made of different materials. However, the proportion of the adhesive in the entire filter element is negligible. When using fusible material for the individual parts of the filter element, an additional adhesive can also be dispensed with entirely, so that in fact, without exception, the same material can be used for the filter element 2 . As already mentioned at the beginning, it enables a filter element made of the same type of material to be disposed of and reprocessed quite easily and inexpensively.

Durch die Ausbildung des Filterelementes 2 mit stirn­ seitig angeordneten Rohren 5 ist eine einfache Dich­ tung des Filterelementes 2 in dem Filtergehäuse 1 möglich. Beim Austauschen des Filterelementes wird das Filterelement 2 bei geöffnetem Filtergehäuse 1 auf in Achsrichtung des Filterelementes fluchtende Stutzen an beiden Hälften des Filtergehäuses 1 ein­ fach aufgesteckt und gegenüber den Stutzen durch je­ weils radial dichtende Dichtringe 6 gedichtet. Der Strömungsweg des zu filternden Mediums ist in den Ausführungsbeispielen der Zeichnung jeweils durch ei­ nen entsprechenden Pfeil angegeben.Due to the design of the filter element 2 with tubes 5 arranged on the end face, a simple device of the filter element 2 in the filter housing 1 is possible. When replacing the filter element, the filter element 2 is plugged in with the filter housing 1 open on nozzles aligned in the axial direction of the filter element on both halves of the filter housing 1 and sealed against the nozzles by respective radially sealing sealing rings 6 . The flow path of the medium to be filtered is indicated in the exemplary embodiments of the drawing by a corresponding arrow.

Bei der Ausführung des Filterelementes 2 nach Fig. 3 sind die axialen Stirnkanten des Filterelementes durch eine durchgehende Papier-Endscheibe 7 gedich­ tet, an die das Rohr 5 einstückig angeformt ist. Bei dieser Ausführung sind die einzelnen Falten des Fil­ terlementes nicht stirnseitig zu Taschen verklebt.In the embodiment of the filter element 2 according to FIG. 3, the axial end edges of the filter element are sealed by a continuous paper end plate 7 , to which the tube 5 is integrally formed. In this version, the individual folds of the fil terlementes are not glued to pockets on the face.

Bei der Ausführung nach Fig. 4 ragt das Rohr 5 axial über das Filterelement 2 hinaus und die radiale Dich­ tung gegenüber dem Filtergehäuse 1 erfolgt dort am Außenumfang des Rohres 5.In the embodiment of Fig. 4, the pipe 5 extends axially through the filter element 2 addition, and the like tung radial relative to the filter housing 1 there is carried on the outer periphery of the tube 5.

Bei der Ausführung nach Fig. 5 ist das Rohr 5 radial außen an dem Filterelement 2 angebracht. Wie in die­ sem Fall die Stirnkanten des Filtermaterials gedich­ tet werden müssen, zeigt die Fig. 6. Dort sind die radial nach außen offenen Faltenzwischenräume durch beispielsweise einen entsprechend radial innen ge­ zackt ausgeführten Papierring 8 abgedeckt. In the embodiment of Fig. 5, the pipe 5 is mounted radially outside of the filter element 2. As the end edges of the filter material must be tet Poem in the sem case, FIG. 6, where the radially outwardly open spaces between the folds are covered by, for example, a corresponding radially inner ge pinks paper ring 8 executed.

In Fig. 1 ist in der axialen Öffnung des Filterele­ mentes 2 ein zusätzliches als Stützzarge dienendes Rohrstück 9 gezeigt. Bei einer Durchströmung von ra­ dial innen nach radial außen kann ein solches Rohr­ stück 9 selbstverständlich auch radial außen an den Falten des Filterelementes 2 angebracht sein.In Fig. 1 in the axial opening of the Filterele element 2, an additional pipe section 9 serving as a supporting frame is shown. With a flow from ra dial inside to radially outside, such a tube piece 9 can of course also be attached radially outside to the folds of the filter element 2 .

Zur Erreichung des erfindungsgemäßen Zweckes ist es wichtig, daß das Filterelement selbst außer den für die Filterfunktion notwendigen Teilen keine weiteren Zusatzteile wie beispielsweise Dichtungen oder Venti­ le aufweist. Denn nur dies gewährleistet eine Redu­ zierung des bei einem Filterwechsel anfallenden Aus­ tauschmaterials auf ein Minimum.It is to achieve the purpose according to the invention important that the filter element itself except for the filter function necessary parts no further Additional parts such as seals or venti le has. Because only this guarantees a Redu adornment of the off when changing the filter exchange material to a minimum.
