Luftfilter, Insbesondere für die Kurbelgehäusebelüftung einer Brennkraftmaschine Air filter, in particular for the crankcase ventilation of an internal combustion engine
Die Neuerung bezieht sich auf einen insbesondere für die Kurbelgehäusebelüftung einer Brennkraftmaschine bestimmten Luftfilter mit einem ringförmigen, radial von außen nach innen durchströmten, stirnseitig durch Endscheiben abge- ^ schlossenen Filtereinsatz, der innerhalb eines topfförmi-. gen Gehäuses axial zwischen Gehäuseboden und Geh&usedeckel abgedichtet eingespannt ist, wobei der Gehäusedeckel zugleich eine stirnseitige Endscheibe des Filtereinsatzes bildet.The innovation relates to one in particular for the Crankcase ventilation of an internal combustion engine Air filter with an annular, radially outwardly internally flowed through, the end face closed by end disks filter insert, which is inside a cup-shaped. the housing axially between the housing base and the housing cover is clamped in a sealed manner, with the housing cover at the same time being an end disk of the filter insert forms.
Bei einem bekannten Filter dieser Art bestehen beide Endscheiben aus Blech. Der Gehäusedeckel, der zugleich die ■* obere stirnseitige Endscheibe des Filtereinsatzes bildet, ist mit mehreren am Umfang gleichmäßig verteilten Hakenverschlüssen gegen den Gehäuserand angezogen.In a known filter of this type, both end plates are made of sheet metal. The housing cover, which is also the ■ * forms the upper end plate of the filter insert, is tightened against the edge of the housing with several hook fasteners evenly distributed around the circumference.

auch der Gehäusedeckel aus elastisch nachgiebigem Kunststoff gebildet sind und der Gehäusedeckel, unter elastischer Verformung seines den Filtereinsatz umgebenden Ringteils in axialer Richtung auf den Gehäuserand zu, mit seinem Außenrand abnehmbar über den außen mit einer Ringwulst versehenen Gehäuserand einsprengbar ist. Nunmehr können die Hakenverschlüsse eingespart werden, was angesichts der großen Stückzahl, jpi die es sich bei derartigen Massenartikeln durchweg handelt, eine beachtliehe Yerbilligung darstellt.also the housing cover made of resilient plastic are formed and the housing cover, with elastic deformation of its ring part surrounding the filter insert in the axial direction towards the edge of the housing, with its outer edge removable over the outside with an annular bead provided edge of the housing can be sprinkled. Now the hook fasteners can be saved, what given the large number of items, jpi that it is with such Mass items consistently acts, represents a considerable approval.
In weiterer Ausgestaltung der Erfindung ist die am Gehäuseboden unter der axialen Einspannkraft anliegende ringförmige Endscheibe mit einer an ihrem inneren Umfang ra-~ dial nach innen vorspringenden Dichtlippe versehen, die einen vom Gehäuseboden in den Hohlraum des Filtereinsatzes hineinragenden Zentrieransatz dichtend umschließt. Hierdurch dichtet die ringförmige Endscheibe gegenüber dem Gehäuseboden sowohl axial als auch radial ab» so daß die wichtige Abdichtung zwischen Rohluftraum und Reinluftraum erheblich verbessert ist.In a further embodiment of the invention, the ring-shaped one resting on the housing base under the axial clamping force is End disk is provided with a sealing lip projecting radially inward on its inner circumference, which sealingly encloses a centering shoulder protruding from the housing base into the cavity of the filter insert. As a result, the annular end plate seals against the housing base both axially and radially, so that the important seal between the raw air space and the clean air space is significantly improved.
In der Zeichnung ist ein Ausführungsbeispiel eines erfindungsgemäßen Luftfilters im Achsschnitt dargestellt.In the drawing is an embodiment of an inventive Air filter shown in axial section.

Die am Gehäuseboden 3 anliegende untere stirnseitige Endscheibe 6 des Filtereinsatzes ist für den Austritt der radial von außen nach innen durch den Filtereinsatz geströmten Luft durch den am Gehäuseboden J5 mündenden Reinluft-Austrittsstutzen 7 ringförmig ausgebildet.insert 5 axially clamped. The housing cover 4 also forms the upper end disk of the filter insert. The lower end plate 6 of the filter insert lying on the housing base 3 is for the exit of the radially from the outside to the inside through the filter insert flowed air through the opening at the bottom of the case J5 Clean air outlet nozzle 7 is annular.

Wenn der Filtereinsatz 5 in das Gehäuse bis zum Anliegen seiner Endscheibe 6 am Gehäuseboden j5 eingesetzt ist, hat der Rand des Gehäusedeckels 4, wie strichpunktiert angedeutet, mit seinem den Filtereinsatz ι · " 5 umgebenden Ringteil 4a vom Gehäuserand 8 axialen Abstand.fabric made. When the filter insert 5 in the housing is inserted until it rests on its end plate 6 on the housing base j5, the edge of the housing cover 4, as Indicated by dash-dotted lines, with its ring part 4a surrounding the filter element 5, it is at an axial distance from the edge of the housing 8.
Durch Abwärtsbiegen des Ringteils 4a ist der Gehäusedeckel j ' , 4 mit'seinem nach innen gerollten Außenrand 9 über ^eineBy bending the ring part 4a downwards, the housing cover j ', 4 with its inwardly rolled outer edge 9 is over ^ a
am Gehäuserand 8 vorgesehene äußere Ringwulst 10 elastisch einsprengbar. Hierdurch ist der Gehäusedeekel 4 am Gehäuserand 8 abnehmbar festgelegt und zugleich ausreichend abgedichtet. Die elastische Terformung des Ringteils 4a in axialer Richtung auf den Gehäuserand zu erzeugt eine axiale Kraft* durch die die ringförmige Endscheibe 6 gegen den Gehäuseboden 3 dichtend angepreßt wird* Beim Ausführungsbeispiel hat die Endseheibe 6 an ihrer Außenseite eine sich an den Gehäuseboden anlegende Ringwulst 11Outer annular bead 10 provided on the edge of the housing 8 is elastic blastable. As a result, the housing cover 4 is on the edge of the housing 8 fixed detachably and at the same time adequately sealed. The elastic deformation of the ring part 4a in the axial direction towards the edge of the housing generates an axial force * by which the annular end plate 6 counteracts the housing base 3 is pressed tightly * In the exemplary embodiment the end disk 6 has an annular bead 11 on its outside that rests against the housing base
