Title
(DE) FILTER MIT EINEM DURCH MINDESTENS EINE VERSTÄRKUNG VERSTÄRKTEN GEHÄUSE
(EN) FILTER WITH A HOUSING THAT IS REINFORCED BY AT LEAST ONE REINFORCEMENT
(FR) FILTRE A CARTER RENFORCE PAR AU MOINS UN ELEMENT DE RENFORCEMENT
Abstract
(DE)
Es wird ein Filter, insbesondere für die Ansaugluft von Brennkraftmaschinen vorgeschlagen, der Versteifungen für die Gehäuseschalen (10, 11) aufweist. Die Versteifung besteht insbesondere aus einer Stütze, bestehend aus einem Hohlstutzen (21) und einem Gewindestutzen (22), wobei diese beiden Stutzen durch eine Schraube (23) fest miteinander verbunden sind. Dadurch kommt eine gute Versteifung des Filtergehäuses zustande, wodurch dessen Eigenschwingungen wirksam unterbunden werden können, wobei das Gesamtgewicht des Filters im wesentlichen gleich bleibt. Das Vorsehen dieser Stütze wird nur möglich durch eine im Filterelement (12) befindliche Aussparung (24), welche eine Zusatzdichtung (25) trägt, die diese Aussparung zum Stutzen hin abdichtet. Dadurch wird eine zuverlässige Abdichtung zwischen Rohseite (14) und Reinseite (15) des Filters erreicht. Zusätzlich kann die Einspannung der Zusatzdichtung zwischen Hohlstutzen (21) und Gewindestutzen (22) das Flachfilterelement zusätzlich stabilisieren.
(EN)
The invention relates to filter, especially for the intake air of an internal combustion engine which filter comprises reinforcements for the housing parts (10, 11). The reinforcement consists especially of a stay consisting of a hollow tube (21) and a threaded tube (22). Said tubes are stably linked with one another by means of a screw (23), thereby allowing a good bracing of the filter housing. The bracing of the filter housing effectively reduces the natural vibration of the housing while the overall weight of the filter remains substantially the same. Provision of such a stay is made possible by a recess (24) in the filter element (12). Said recess carries an additional seal (25) which seals the recess towards the tube. In this manner, the raw side (14) and the clean side (15) of the filter are reliably sealed from one another. In addition, the mounting of the additional seal between the hollow tube (21) and the threaded tube (22) can additionally stabilize the flat filter element.

L'invention concerne un filtre, en particulier pour l'air d'aspiration d'un moteur à combustion interne, présentant des moyens de renforcement pour les enveloppes du carter (10, 11). Ces moyens de renforcement sont constitués notamment par un support comprenant un tube (21) et un manchon fileté (22), ces deux éléments tubulaires étant reliés rigidement entre eux au moyen d'une vis (23). On obtient ainsi un bon renforcement du carter de filtre, permettant de supprimer efficacement ses oscillations propres, le poids total du filtre restant sensiblement inchangé. L'agencement de ce support n'est réalisable que grâce à un évidement (24) ménagé dans l'élément du filtre (12), un joint supplémentaire (25) assurant par ailleurs l'étanchéité du support. On obtient ainsi toute garantie d'étanchéité entre la face brute (14) et la face propre (15) du filtre. En outre, le blocage du joint supplémentaire entre le tube (21) et le manchon fileté (22) peut stabiliser davantage l'élément de filtre plat.
