Insbesondere kann der erfindungsgemäße Ventilstab bei einem gattungsgemäßen Filter gegen einen solchen ohne ein Über strömventil ausgetauscht werden, ohne an dem Verschlußdek kel oder dem Filtergehäuse Änderungen vornehmen zu müssen. Es handelt sich damit für bestehende Filter um eine prakti sche Nachrüsteinrichtung für solche Fälle, in denen ein Überströmventil nicht vorgesehen war.In particular, the valve rod according to the invention can be used in a generic filter against such without an over flow valve can be replaced without the Dek kel or the filter housing to make changes. It is therefore a practi for existing filters retrofit for cases where a Overflow valve was not provided.
Die erfindungsgemäße Lösung eignet sich auch für Fälle, in denen insbesondere in dem Verschlußdeckel bereits ein Über strömventil fest mit diesem verbunden vorhanden war. In diesen Fällen braucht nur der Deckel gegen einen solchen für eine Aufnahme eines erfindungsgemäßen Ventilstabes aus getauscht zu werden.The solution according to the invention is also suitable for cases in which, especially in the cover, already has an over flow valve was firmly connected to this. In In these cases, only the lid needs one for receiving a valve rod according to the invention to be exchanged.
Zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche und werden im Zusammenhang mit einem noch zu beschreibenden Ausführungsbeispiel näher erläutert werden.Appropriate embodiments of the invention are the subject matter of the subclaims and are in connection with one Embodiment yet to be described will.

Diese zeigt
einen Schnitt durch einen Verschlußdeckel
für ein Filtergehäuse zusammen mit einem
in dem Verschlußdeckel gelagerten Ventil
stab.This shows
a section through a cap for a filter housing together with a valve rod mounted in the cap.
Der Verschluß-Deckel 1 ist mit einem Gewinde versehen, um von lotrecht oben auf ein topfförmiges Gehäuse eines Fil ters aufgeschraubt werden zu können.The closure lid 1 is provided with a thread in order to be screwed vertically from above onto a pot-shaped housing of a filter.
In den Verschluß-Deckel 1 ist lösbar ein Ventilstab 2 ein geschnappt. Dieser Ventilstab 2 verschließt mit seinem un teren Ende 3 eine Abflußöffnung in dem Filtergehäuse (nicht dargestellt) bei geschlossenem Deckel 1. Bei geöffnetem Deckel 1 ist die betreffende Abflußöffnung des Filtergehäu ses für einen freien Abfluß freigegeben.In the closure cover 1 a valve rod 2 is releasably snapped. This valve rod 2 closes with its lower end 3 a drain opening in the filter housing (not shown) when the lid is closed. 1 When the lid 1 is open, the relevant drain opening of the filter housing is released for free drainage.
In dem oberen Bereich des Ventilstabes ist radial dicht ein Ringfilter-Element 4 gelagert. Das Ringfilter-Element 4 kann von radial außen nach innen durchströmt werden.In the upper area of the valve rod, a ring filter element 4 is radially sealed. The ring filter element 4 can be flowed through from radially outside to inside.
Den oberen Bereich des Ventilstabes 2, über den dieser an dem Deckel 1 befestigt ist, bildet ein Trägerteil 5. Dieses Trägerteil 5 ist einerseits über einen Schnappverschluß mit dem unteren Teil des Ventilstabes 2 verbunden und anderer seits ebenfalls über einen Schnappverschluß in dem Deckel 1 gehalten.The upper region of the valve rod 2 , by means of which it is attached to the cover 1 , forms a carrier part 5 . This carrier part 5 is connected on the one hand via a snap lock to the lower part of the valve rod 2 and on the other hand also held in the cover 1 via a snap lock.
Eine zentrale Öffnung in dem Trägerteil 5 bildet einen Teil des Überströmventiles 6. Diese Öffnung stellt eine Verbin dung zwischen Rein- und Rohraum des Filters dar.A central opening in the carrier part 5 forms part of the overflow valve 6 . This opening represents a connection between the clean and tube space of the filter.
Verschlossen gehalten wird diese Öffnung durch eine Ventil platte 7, die unter der Kraft einer Feder 8 von unten an die vorgenannte Öffnung dicht angedrückt wird. Die Feder 8 stützt sich einerseits an dem oberen Öffnungsrand des Trä gerteiles 5 ab und zum anderen an einer mit der Ventilplat te 7 fest verbundenen Halterung 9.This opening is kept closed by a valve plate 7 , which is pressed tightly under the force of a spring 8 from below to the aforementioned opening. The spring 8 is based on the one hand on the upper opening edge of the Trä gerteiles 5 and on the other hand on a te with the Ventilplat te 7 bracket 9th
Die Halterung 9 kann ein Blechteil sein, das mit der Ven tilplatte 7 vernietet ist.The bracket 9 may be a sheet metal part which is riveted to the Ven tilplatte 7 .
Die Montage des Überströmventiles 6 erfolgt in der Weise, daß bei noch nicht mit dem unteren Teil des Ventilstabes 2 verbundenem Trägerteil 5 die Ventilplatte 7 von der unteren Seite an den Öffnungsrand des Trägerteiles 5 angelegt wird und die Halterung 9 von der anderen Seite der Öffnung an greifend mit der Ventilplatte 7 vernietet wird. Danach wird das Trägerteil 5 auf das untere Teil des Ventilstabes 2 aufgeschnappt. Die Trennung zwischen unterem Teil des Ven tilstabes 2 und dem Trägerteil 5 ist allein für die vorge nannte Art der Montage des Überströmventiles 6 notwendig und zweckmäßig. Grundsätzlich könnte das Trägerteil 5 auch mit dem übrigen Teil des Ventilstabes 2 ein kompaktes ein heitliches, nicht in Einzelteile auftrennbares, Kompaktteil sein. Der beschriebene Ventilstab 2 zusammen mit dem Ver schlußdeckel i wird besonders vorteilhaft bei lotrecht an geordneten Ölfiltern für Verbrennungsmotoren eingesetzt.The overflow valve 6 is mounted in such a way that when the carrier part 5 is not yet connected to the lower part of the valve rod 2 , the valve plate 7 is applied from the lower side to the opening edge of the carrier part 5 and the holder 9 from the other side of the opening is riveted to the valve plate 7 . Then the carrier part 5 is snapped onto the lower part of the valve rod 2 . The separation between the lower part of the Ven tilstabes 2 and the support member 5 is necessary and appropriate solely for the aforementioned type of mounting the relief valve 6 . In principle, the carrier part 5 could also be a compact, uniform, compact part that cannot be separated into individual parts with the remaining part of the valve rod 2 . The valve rod 2 described together with the United cover lid i is particularly advantageously used in perpendicular to ordered oil filters for internal combustion engines.
