Die oben genannten Lösungen zur Befestigung der Membran haben den Nachteil, dass ein zusätzliches Fixierelement gefertigt und montiert werden muss, oder ein zusätzlicher Prozessschritt zur Befestigung der Membran notwenig ist.The above solutions for fixing the membrane have the disadvantage that made an additional fixing and must be mounted, or an additional process step necessary for attachment of the membrane.
Offenbarung der ErfindungDisclosure of the invention
Die erfindungsgemäße Vorrichtung und das erfindungsgemäße Verfahren mit den Merkmalen der unabhängigen Ansprüche haben den Vorteil, dass das Filterelement als ein Bauteil vorgefertigt werden kann, das ohne zusätzlichen Verbin dungsprozess direkt in die Vertiefung des Gehäuses einsetzbar ist. Durch die angeformten Fortsätze quer zur Einfügerichtung des Filterelements ist dieses zuverlässig in der Vertiefung gesichert, so dass auch bei unterschiedlichen Betriebsbedingungen eine zuverlässige Abdichtung des Gehäuses gewährleistet ist. Dadurch entfällt beispielsweise die Verwendung von zusätzlichen Sicherungsmitteln, die in einem zusätzlichen Montageprozess montiert werden müssten.The Inventive device and the invention Method with the features of the independent claims have the advantage that the filter element prefabricated as a component can be done without additional connection process directly can be used in the recess of the housing. By the molded extensions transverse to the insertion direction of the filter element, this is reliable in the recess secured, so even under different operating conditions ensures a reliable sealing of the housing is. This eliminates the use of, for example additional securing means in an additional assembly process would have to be mounted.
Durch die in den abhängigen Ansprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der in den unabhängigen Ansprüchen angegebenen Ausführungen möglich. Besonders vorteilhaft kann das Filterelement als vorgefertigte Baueinheit hergestellt werden, die dann vorteilhaft nach dem gesamten Zusammenbau des Gehäuses nachträglich in die Gehäusevertiefung eingepresst werden kann. Durch die Montage in Öffnungsrichtung wird das Filterelement durch die an die Seitenwände angeformten Fortsätze quer zur Öffnungsrichtung nach der Montage an einem Herausfallen gehindert. Das Filterelement weist mindestens eine sich über dessen gesamten Umfang sich erstreckende Dichtrippeauf, die beim Einfügen des Filterelements an die Seitenwand gepresst wird und diese gegen das Filterelement abdichtet. Dadurch sind keine weiteren separaten Dichtelemente notwendig.By those listed in the dependent claims Measures are advantageous developments and improvements that specified in the independent claims Versions possible. Particularly advantageous can the filter element are manufactured as a prefabricated unit, which then advantageous after the entire assembly of the housing subsequently pressed into the housing recess can be. By mounting in the opening direction is the filter element by integrally formed on the side walls Projections transverse to the opening direction after assembly prevented from falling out. The filter element has at least one extending over its entire circumference Dichtrippeauf, when inserting the filter element to the side wall is pressed and this seals against the filter element. Thereby no further separate sealing elements are necessary.
Das Filterelement ist vorzugsweise kreisrund ausgebildet, wobei an einem Grundkörper einerseits eine gasdruchlässige, flüssigkeitsundurchlässige Membran angeordnet ist, und andererseits elastische Dichtlippen angespritzt sind, die einen Presssitz in der Gehäusevertiefung ermöglichen.The Filter element is preferably circular, wherein at one Basic body on the one hand a gas-permeable, liquid-impermeable membrane is arranged, and molded on the other hand elastic sealing lips are that allow a press fit in the housing recess.
Die angeformten Fortsätze quer zur Öffnungsrichtung sind günstigerweise als mehrere Kreisringsegmente ausgeführt, so dass sich die Dichtrippen leichter über die Fortsätze hinwegschieben lassen. Dadurch müssen dann die Dichtrippen nicht über ihren gesamten Umfang verformt werden. In Abhängigkeit der Belastungsanforderungen an das Gehäuse, insbesondere bezüglich Erschütterung und Temperaturwechsel, sind vorzugsweise zwei, drei oder vier Segmente als Fortsätze der Seitenwand angeformt. Bei größeren Durchmessern der Gehäusevertiefung können beispielsweise aber auch fünf oder sechs oder mehr Kreisringsegmente angeordnet sein.The molded extensions transverse to the opening direction are conveniently designed as multiple annular segments, so that the sealing ribs more easily over the extensions let it slide away. As a result, then have the sealing ribs not be deformed over its entire circumference. Dependent on the load requirements to the housing, in particular regarding vibration and temperature change, are preferably two, three or four segments as extensions the side wall formed. For larger diameters but can the housing recess, for example also be arranged five or six or more circular ring segments.
Günstigerweise sind dabei die Abstände zwischen den Segmenten über den Umfang näherungsweise gleich groß, da hierdurch eine Verformung der Dichtrippen beim Einfügen des Filterelements erleichtert wird.conveniently, are the distances between the segments over the circumference is approximately the same size, as a result a deformation of the sealing ribs when inserting the filter element is relieved.
Vorteilhaft ist es, wenn die Ausdehnung der Fortsätze quer zur Montagerichtung des Filterelements geringer ist, als die Höhe der Dichtlippen bezüglich des Grundkörpers des Filterelements. Dadurch können beim Einpressen des Filterelements die Dichtlippen derart verformt werden, dass sie sich entlang der Öffnungsrichtung über die Fortsätze schieben lassen. Dadurch werden die Dichtlippen beim Einfügen des Filterelements nicht beschädigt.Advantageous It is when the extension of the extensions transverse to the mounting direction of the filter element is less than the height of the sealing lips with respect to the main body of the filter element. As a result, when pressing the filter element, the sealing lips be deformed so that they over the opening direction over let the extensions slide. As a result, the sealing lips in Inserting the filter element is not damaged.
Vorzugsweise wird das erfindungsgemäße Gehäuse für Verstellantriebe im Kraftfahrzeug angewendet, beispielsweise für Fensterheberantriebe oder Schiebedachantriebe, um den Motor gegen Feuchtigkeit und eindringendes Wasser zu schützen und gleichzeitig ein Druckausgleich bei die Temperaturschwankungen zuzulassen.Preferably is the housing according to the invention for Adjustment drives used in the motor vehicle, for example for Window regulators or sunroof drives to keep the engine from getting wet and to protect and penetrate water at the same time Allow pressure equalization at the temperature fluctuations.
Besonders kostengünstig können die Fortsätze quer zur Öffnungsrichtung einstückig mit dem Gehäuseteil ausgebildet werden, vorzugsweise mittels Kunststoffspritzgussverfahren. Das Filterelement kann dabei als unabhängig vom Gehäuse hergestelltes Bauteil gefertigt werden, an dem Dichtrippen angeformt sind, die verglichen mit dem Grundkörper elastischer ausgebildet sind. Diese elastischen Dichtrippen lassen sich beim Einschieben über die Fortsätze entsprechend verformen und bilden danach einen Presssitz mit den Seitenwänden der Gehäusevertiefung. Gleichzeitig bilden. die Fortsätze eine zuverlässige Sicherung gegen das Herausfallen des Filterelements.Particularly cost-effective, the extensions can be formed integrally with the housing part transversely to the opening direction, preferably by means of plastic injection molding. The filter element can be made as a component manufactured independently of the housing, on the sealing ribs are formed, which are formed elastic compared to the main body. These elastic sealing ribs can be correspondingly deform when pushed over the extensions and then form a press fit with the side walls of the housing recess. At the same time form. the extensions a reliable safeguard against falling out of the filter element.
In einer bevorzugten Ausführung wird das Filterelement soweit in die Gehäusevertiefung eingepresst, dass nach der Montage des Filterelements die Fortsätze bezüglich der Montagerichtung an der mindestens einen Dichtrippe anliegen. Dadurch wird die Haftreibung der Dichtlippe unterstützt und ein Losrütteln des Filterelements von Anfang an komplett unterbunden.In In a preferred embodiment, the filter element is so far pressed into the housing recess that after assembly the filter element, the extensions with respect to the Mounting direction abut the at least one sealing rib. Thereby the stiction of the sealing lip is supported and a shaking loose the filter element completely prevented from the beginning.
