Abstract
In ein Filtergehäuse austauschbar einsetzbares Ringfilterelement mit die Stirnkanten abdeckenden Endscheiben, wobei mindestens eine der Endscheiben (4) aus einem kompakten, relativ starren, jedoch noch geringfügig elastischen Material besteht und radial innen und/oder außen einen als radiale Dichtung vorgesehenen ringförmigen, in der Ebene der Endscheibe (4) liegenden und mit dieser einstückig gebildeten Überstand (5) besitzt, der eine radiale Breite aufweist, durch die dieser Überstand (5) bei Anlegen an eine radiale Gegendichtfläche des Filters eine nur geringfügig gegenüber der Endscheibenebene gekippte Lage einnimmt.In a filter housing interchangeable insertable ring filter element with the end edges covering end discs, wherein at least one of the end discs (4) from a compact, relatively rigid, but still slightly elastic Material exists and radially inside and / or outside as a radial seal provided annular, in the plane of the end plate (4) lying and integrally formed with this supernatant (5) having a radial width through which this projection (5) when applied to a radial mating surface of the filter, only slightly opposite to End disc level assumes tilted position.
Description
Die Erfindung betrifft ein in ein Filtergehäuse austauschbar einsetzbares Ringfilterelement mit die Stirnkanten abdeckenden Endscheiben. Das Ringfilterelement ist über mindestens eine ihrer Endscheiben radial innen und/oder außen gegenüber einer Anlagefläche des Filtergehäuses über eine radial wirkende Dichtung gedichtet.The The invention relates to an insertable into a filter housing replaceable Ring filter element with the end edges covering end plates. The Ring filter element is over at least one of its end disks radially inward and / or outward with respect to a contact surface of the Filter housing over a sealed radially acting seal.
Bei Ringfilterelementen mit relativ weichen Endscheiben aus beispielsweise Vlies ist es möglich, einen vorgesehenen radial ringförmigen Überstand der Endscheiben für ein radiales Dichten des Ringfilterelementes gegenüber einer Aufnahme zu benutzen. Die Dichtung wird dadurch bewirkt, dass das relativ weiche Endscheibenmaterial zwischen einer festen Anlagefläche an dem Ringfilterelement und einer festen Gegenaufnahmefläche radial dicht verpresst wird. Der radiale Überstand wird dabei um etwa 90° in die zu verpressende Lage umgebogen. Derartige Dichtungen sind äußerst kostengünstig, da sie durch lediglich eine geringfügige, gezielte Vergrößerung der Endscheiben geschaffen werden können.at Ring filter elements with relatively soft end plates, for example Fleece is it possible to have one provided radially annular projection of the End discs for a radial sealing of the ring filter element with respect to a To use recording. The seal is caused by the fact that relatively soft Endscheibenmaterial between a fixed contact surface on the Ring filter element and a fixed counter-receiving surface radially is pressed tightly. The radial projection is about 90 ° in the bent to be pressed position. Such seals are extremely inexpensive, as they by only a slight, targeted enlargement of the End discs can be created.
In bestimmten Anwendungsfällen werden bei Ringfilterelementen relativ starre Endscheiben gewünscht. In diesen Fällen ist eine Dichtwirkung auf die vorgenannte Art nicht möglich, da das Dichtscheibenmaterial einerseits für ein Umklappen um etwa 90° zu steif ist und andererseits auch nicht in einem für jenes Dichtprinzip notwendigen Maße komprimierbar ist.In certain applications are desired in ring filter elements relatively rigid end plates. In these cases is a sealing effect in the aforementioned manner not possible because the sealing disc material on the one hand for folding over by about 90 ° too stiff and, on the other hand, not in a necessary for that sealing principle Dimensions compressible is.

Für ein Ringfilterelement mit einer relativ starren Endscheibe eine wirtschaftlich erzielbare Dichtungsmöglichkeit innerhalb eines Gehäuses zu schaffen, ist das Problem, mit dem sich die Erfindung beschäftigt.For a ring filter element with a relatively rigid end plate economically achievable sealing possibility within a housing to create is the problem with which the invention deals.
Eine Lösung hierzu stellt eine Ausführung eines Ringfiltereinsatzes mit den Merkmalen des Anspruchs 1 dar.A solution this is an implementation a ring filter insert with the features of claim 1.
Die Erfindung beruht dabei auf dem Gedanken, die hohe Anpresskraft eines nur leicht aus der Ebene gekippten relativ steifen Ringes auszunutzen.The The invention is based on the idea of the high contact pressure of a exploit only slightly out of the plane tilted relatively stiff ring.
Bei der erfindungsgemäßen Dichtung ist jeweils anzustreben, den Dichtrand in eine solche Richtung zu kippen, dass der zwischen den gegeneinander abgedichteten Räumen herrschende Differenzdruck in Richtung eines Geradebiegens des Dichtrandes wirkt.at the seal according to the invention is to strive respectively, the sealing edge in such a direction tilt that prevails between the mutually sealed rooms Differential pressure in the direction of a straight bending of the sealing edge acts.
Insbesondere, wenn eine solche Einbaulage konstruktiv nicht möglich ist, sollte für einen Anschlag des abgebogenen Dichtrandes an der Gegendichtfläche, an der der Dichtrand anliegt, gesorgt werden.Especially, If such an installation position is structurally impossible, should be for a Stop of the bent sealing edge on the counter surface, on the sealing edge rests, be taken care of.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.One embodiment the invention is shown in the drawing.
Diese zeigt in schematischer Darstellung ein Filtergehäuse mit einem eingesetzten Ringfilterelement.These shows a schematic representation of a filter housing with an inserted Ring filter element.
Das
Filtergehäuse
besteht aus einem topfförmigen
Unterteil
Das
Ringfilterelement wird von radial außen nach innen durchströmt. Auf
diese Weise ist der radiale Überstand
In
dem Deckel des Filters ist als Sicherheitsvorkehrung gegen ein zu
weites Umbiegen des Überstandes
Der große Vorteil der Erfindung besteht darin, für die Dichtung des Ringfilterelementes in einem Gehäuse außer einem einfachen radialen Überstand mindestens einer der Endscheiben des Ringfilterelementes keine weiteren Maßnahmen zu benötigen. Der radiale Überstand muss insbesondere keine besondere Form aufweisen, sondern kann vielmehr praktisch eine einfache Ringscheibe mit etwa rechteckigem Querschnitt sein.Of the size Advantage of the invention is, for the seal of the ring filter element in a housing except a simple radial projection at least one of the end plates of the ring filter element no further action to need. Of the radial supernatant in particular, does not have to have any particular shape, but rather can be practical be a simple annular disc with approximately rectangular cross-section.
