Description

Die Erfindung betrifft eine Demontagehilfe für Filter­ gehäuse nach dem Oberbegriff des Patentanspruchs.The invention relates to a disassembly aid for filters Housing according to the preamble of the claim.

Derartige Demontagehilfen sind z.B. aus der US-PS 28 86 180 bekannt. Der Mitnehmer ist dort ein Sprengring, der in einer in der Löse-Schraube vorgesehenen Ringnut angreift. Dieser Sprengring ist damit ein separates Teil, das nach Einstecken der Schraube in den Gehäusedeckel in der betreffenden Schrauben-Ringnut befestigt werden muß.Such disassembly aids are e.g. from the US-PS 28 86 180 known. The driver is there a snap ring in one in the release screw provided ring groove attacks. This snap ring is thus a separate part, which after inserting the Screw in the housing cover in the concerned Screw ring groove must be fastened.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, den Aufbau der Demontagehilfe zu verbessern, damit mit der Montage des Mitnehmers nicht bis nach dem Einführen der Schraube in den Gehäusedeckel ge­ wartet werden muß und es möglich ist, die Herstellungs­ kosten zu senken.Proceeding from this, the object of the invention to improve the structure of the disassembly aid, so with the assembly of the driver not until after inserting the screw into the housing cover must be maintained and it is possible to manufacture cut costs.

Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Patentanspruchs.This task is solved by the characteristic Features of the claim.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.An embodiment is shown in the drawing.

Das Filtergehäuse besteht aus einem Gehäuse-Hauptteil 1 und einem glockenartig ausgebildeten Gehäusedeckel 2. Das Gehäuse-Hauptteil 1 kann aus Aluminium und der Deckel 2 aus einem Kunststoff sein. Der Gehäusedeckel 2 ist mit Hilfe einer Schraube 3 mit dem Gehäuse-Hauptteil 1 ver­ bunden. Die Schraube 3 weist einen an dem Gehäusedeckel 2 angreifenden Schraubenkopf auf und greift an dem Gehäuse-Hauptteil 1 in eine Gewindebohrung 4 ein. Die Dichtung zwischen Gehäusedeckel 2 und Hauptteil 1 erfolgt radial über einen Dichtring 5.The filter housing consists of a main housing part 1 and a bell-shaped housing cover 2 . The main housing part 1 can be made of aluminum and the cover 2 made of a plastic. The housing cover 2 is ver with the help of a screw 3 with the main body part 1 . The screw 3 has a screw head engaging on the housing cover 2 and engages on the housing main part 1 in a threaded bore 4 . The seal between the housing cover 2 and the main part 1 takes place radially via a sealing ring 5 .

In die Schraube 3 ist eine Ringnut 9 eingearbeitet, in die ein Schnappelement 10 eingreift, das über ein Rohrteil 8 an den Gehäusedeckel 2 angeformt ist. Wird die Schraube 3 zum Abnehmen des Gehäusedeckels 2 und Wechseln des Filtereinsatzes 7 gelöst, so schlägt das Schnappelement 10 an die Unterflanke (11) der Ring­ nut 9 und hebt bei weiterem Lösen der Schraube den Ge­ häusedeckel 2 von dem Gehäuse-Hauptteil 1 ab.In the screw 3 , an annular groove 9 is worked into which a snap element 10 engages, which is formed on the housing cover 2 via a tubular part 8 . If the screw 3 for removing the housing cover 2 and changing the filter insert 7 is loosened, the snap element 10 strikes the lower flank ( 11 ) of the ring groove 9 and lifts the housing cover 2 from the housing main part 1 when the screw is loosened further.

Das Schnappelement (10) kann aus einzelnen biegsamen Laschen ausgebildet sein, die sich an den inneren Umfang der Ringnut (9) anlegen. Dabei sind diese Laschen als ein Art Widerhaken in der Weise ausgebildet, daß die Schraube (3) zwar in den Gehäusedeckel 2 eingeführt werden kann, wobei die Laschen des Schnappelementes (10) in die Ringnut einspringen, aber ein anschließendes Herausziehen der Schrauben dann nur noch über die Höhe der Ringnut möglich ist. Auf diese Weise legt sich die Unterflanke (11) der Ringnut (9) beim Lösen der Schrauben so an das Schnappelement (10) an, daß sich bei weiterem Herausdrücken der Schraube der Gehäusedeckel 2 von dem Gehäuse-Hauptteil 1 abhebt.The snap element ( 10 ) can be formed from individual flexible tabs which lie against the inner circumference of the annular groove ( 9 ). These tabs are designed as a kind of barb in such a way that the screw ( 3 ) can be inserted into the housing cover 2 , the tabs of the snap element ( 10 ) jumping into the annular groove, but then only then removing the screws over the height of the ring groove is possible. In this way, the lower flank ( 11 ) of the annular groove ( 9 ) rests on the snap element ( 10 ) when the screws are loosened in such a way that the housing cover 2 stands out from the main housing part 1 when the screw is further pushed out.
