Abstract
Description
Die Erfindung betrifft ein Filter, insbesondere Ölfilter zum Reinigen von Schmieröl nach dem Oberbegriff des Patent anspruchs 1. Ein solches Schmierölfilter ist beispielsweise aus DE 39 03 675 C2 bekannt.The invention relates to a filter, in particular an oil filter for cleaning lubricating oil according to the preamble of the patent claims 1. Such a lubricating oil filter is for example known from DE 39 03 675 C2.
Dort gibt beim Filterelementwechsel ein an einer Endscheibe angeformter Verschlußstopfen einen Abflußkanal frei, damit das im Filtergehäuse enthaltene Öl ablaufen kann.There is an end plate when changing the filter element molded plug a drain channel free so the oil contained in the filter housing can drain off.
Das Anbringen eines derartigen Stopfens an der Endscheibe bringt verglichen mit konventionellen Filterelementen einen deutlich erhöhten Aufwand mit sich. Insbesondere muß der Abstand zwischen dem zentralen Ablaufstutzen und dem Ver schlußstopfen eng toleriert werden, um gute Montierbarkeit und Dichtheit zu gewährleisten. Wenn der Verschlußstopfen nicht exakt mit dem Abflußkanal fluchtet, so können bei der Montage des Deckels relativ große Kräfte auf das Filterele ment kommen, die - insbesondere bei Filterelementen ohne Zargen - zu einer Verformung des Filterelements führen.Attaching such a plug to the end plate brings one compared to conventional filter elements significantly increased effort. In particular, the Distance between the central drain pipe and the ver end plugs are tightly tolerated to ensure easy assembly and to ensure tightness. If the plug not exactly aligned with the drainage channel, so the Installation of the cover relatively large forces on the Filterele ment come that - especially with filter elements without Frames - lead to deformation of the filter element.
Die Erfindung beschäftigt sich deshalb mit dem Problem bei dem gattungsgemäßen Ölfilter die Funktion "Filterelement" von der Funktion "Schließen eines Abflußkanals" so zu tren nen, daß am Filterelement kein Verschlußstopfen angeformt werden muß und daß das Filterelement weder bei der Montage noch beim Betrieb Axialkräfte für die Funktion "Schließen eines Abflußkanals" übertragen muß.The invention is therefore concerned with the problem the generic oil filter the function "filter element" so from the function "closing a drainage channel" NEN, that no sealing plug is formed on the filter element must be and that the filter element neither during assembly axial forces during operation for the "Closing a drain channel "must transmit.
Dieses Problem wird durch eine Ausgestaltung des Filters nach den kennzeichnenden Merkmalen des Patentanspruchs 1 gelöst. Im Vergleich zu den aus der Praxis bekannten Lösun gen besitzt die erfindungsgemäße Lösung insbesondere den Vorteil, daß das Filterelement im Betrieb keine Axialkräfte übertragen muß und deshalb ohne axial abstützende Zargen gefertigt werden kann. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche.This problem is solved by designing the filter according to the characterizing features of claim 1 solved. In comparison to the solutions known from practice gene, the solution according to the invention has in particular the Advantage that the filter element has no axial forces during operation must transfer and therefore without axially supporting frames can be manufactured. Advantageous further developments are Subject of the subclaims.
Weitere Vorteile und Merkmale der vorliegenden Erfindung ergeben sich aus der nachfolgenden Beschreibung eines be vorzugten Ausführungsbeispiels anhand der Zeichnung.Further advantages and features of the present invention result from the following description of a be preferred embodiment with reference to the drawing.
Es zeigtIt shows
Fig. 1 einen Querschnitt durch das Filter. Fig. 1 shows a cross section through the filter.
Das Ölfilter 1 besteht aus einem Filtertopf 2, einem aufschraubbaren Filterdeckel 3 und einem auswechselbaren Filterelement 4. Im Filtertopf 2 liegt eng an dessen In nenkontur ein becherartiges Bauelement 5, mit einem Bo den 8, der zumindest eine Durchtrittsöffnung aufweist. Am Boden 8 ist ein Verschlußstopfen 9 fixiert, der einen Leerlaufkanal 10 abdichtet. Baulänge und Durchmesser des Bechers 5 sind so ausgelegt, daß der Becher 5 bei der Montage des Schraubdeckels 3 von diesem stirnseitig über einen Flansch 7 in seine, den Leerlaufkanal 10 mittels des Verschlußstopfens 9 abdichtende, Position geschoben wird.The oil filter 1 consists of a filter bowl 2 , a screw-on filter cover 3 and an exchangeable filter element 4 . In the filter bowl 2 is close to the In nenkontur a cup-like component 5 , with a Bo 8 , which has at least one passage opening. At the bottom 8 , a plug 9 is fixed, which seals an idle channel 10 . The overall length and diameter of the cup 5 are designed so that the cup 5 is pushed from the front side by a flange 7 into its position when the screw cap 3 is assembled, into a position that seals the idle channel 10 by means of the sealing plug 9 .
Am Becher 5 und am Filtertopf 2 sind Führungen 11 und 12 angebracht, die ein Einschieben des Bechers 5 in den Filtertopf 2 nur in einer den Verschlußstopfen 9 auf den Abflußkanal 10 ausrichtenden Position zulassen.Guides 11 and 12 are attached to the cup 5 and the filter bowl 2 , which allow the cup 5 to be pushed into the filter bowl 2 only in a position which aligns the sealing plug 9 with the drain channel 10 .
Bei Demontage des Schraubdeckels 3 wird der Becher 5 durch eine konzentrisch zum Verschlußstopfen 9 ange brachte Feder 6 axial so verschoben, daß der Leerlaufka nal 10 frei wird und das noch im Gehäuse befindliche Öl ablaufen kann.When dismantling the screw cap 3 , the cup 5 is axially displaced by a spring 6 , which is brought concentrically with the sealing plug 9 , so that the idle channel 10 becomes free and the oil still in the housing can drain off.
