Die Erfindung betrifft ein Flüssigkeitsfilter mit einem becherförmigen Gehäuse.The invention relates to a liquid filter with a cup-shaped housing.
Aufgabe der Erfindung ist es, ein Flüssigkeitsfilter in zweckmäßiger Ausbildung zu schaffen.The object of the invention is to create a liquid filter in an expedient design.
Ein Flüssigkeitsfilter gemäß der Erfindung ist dadurch gekennzeichnet, daß eine Nut um die Innenseite des Öffnungsrandes des becherförmigen Gehäuses herum und ein tangential in die Nut hineinführender Einlaß für die zu filtrierende Flüssigkeit vorgesehen sind, daß sich in einem Deckel des Gehäuses ein Flüssigkeitsauslaß befindet, daß eine Hülse in dem Gehäuse zum Umlenken der in das Gehäuse einfließenden Flüssigkeit in Richtung auf dessen geschlossenes Ende vorA liquid filter according to the invention is characterized in that that a groove around the inside of the opening edge of the cup-shaped housing and one tangential Into the groove leading inlet for the liquid to be filtered are provided that are in a cover of the housing a liquid outlet is located that a sleeve in the housing for diverting the flowing into the housing Liquid in the direction of its closed end

Die Erfindung ist im nachfolgenden an Hand eines Ausführungsbeispiels unter Bezugnahme auf die beiliegenden Zeichnungen näher beschrieben. In den Zeichnungen sind:The invention is described below on the basis of an exemplary embodiment with reference to the accompanying drawings described in more detail. In the drawings are:
Fig. 1 ein axialer Schnitt durch ein Flüssigkeitsfilter,Fig. 1 is an axial section through a liquid filter,
Fig· 2 eine Einzelheit im Schnitt an der Linie II-II der Fig· 1, undFig. 2 is a detail in section on the line II-II of Figures 1, and
Fig. 5 ein Schnitt an der Linie III-III der Fig. 1·Fig. 5 is a section on the line III-III of Fig. 1.
Das Filter weist ein Gehäuse 1o auf, das in einem äußeren Gehäuse sitzt, von dem ein Teil 11 gezeigt ist. Das Gehäuse ist im wesentlichen becherförmig ausgebildet, und am Qffnungsrand befindet sich an der Innenseite eineNut 12. Diese Nut steht mit einem tangentialen Einlaß 15 in der Wand des Gehäuses 1o in Verbindung. Dieser Einlaß wiederum steht mit einem Einlaßkanal 14 im Gehäuse 11 in Verbindung. Die Jüut 12 ist spiralförmig ausgebildet und nimmt in ihrer Tiefe in Richtung vom Einlaß 13 ab, bis sie nach einer vollen Umdrehung um die Innenseite des Gehäuses herum vollkommen verschwindet.The filter has a housing 1o which is in an outer housing sits, of which a part 11 is shown. The housing is essentially cup-shaped and at the edge of the opening there is a groove 12 on the inside. This groove stands with a tangential inlet 15 in the wall of the housing 1o in connection. This inlet is in turn connected to an inlet channel 14 in the housing 11. The Jüut 12 is spiral-shaped formed and decreases in depth in the direction of the inlet 13 until after a full revolution around the inside of the housing disappears completely.
Das Gehäuse 1o ist mit einem Deckel 15 versehen, der dichtend in die öffnung des Gehäuses 1o paßt· Der Deckel 15 weist in der Mitte einen Flüssigkeitsauslaß 16, auf, durch den fil-The housing 1o is provided with a cover 15 which is sealing fits into the opening of the housing 1o The lid 15 has a liquid outlet 16 in the middle through which the fil-

trierte Flüssigkeit das Gehäuse über eine Auslaßöffnung 21
und einen damit fluchtenden Auslaßkanal 22 im Gehäuse 11 verläßt. Innerhalb des Gehäuses 1o sitzt eine zylindrische Hülse
17, die den Filtereinsatz 18 umgibt. Die Hülse ist gegen den
Deckel 15 abgedichtet.liquid traversed the housing via an outlet opening 21
and an outlet channel 22 in the housing 11 which is aligned therewith. A cylindrical sleeve 17, which surrounds the filter insert 18, sits inside the housing 1o. The sleeve is against that
Cover 15 sealed.
Ein Leitring 19 weist eine Anzahl im Abstand angeordneter Öffnungen
2o auf, die dadurch gebildet sind, daß der Hing 19
axial geschlitzt wird und Bereiche des Rings zu einer Seite
eines jeden dieser Schlitze eingedrückt werden.A guide ring 19 has a number of spaced apart openings 2o, which are formed in that the Hing 19
is axially slotted and areas of the ring to one side
of each of these slots.
Im Betrieb fließt die in die Hut 12 gelangende Flüssigkeit von der iiut 12 in den Ringraum zwischen der Hülse 17 und dem Gehäuse
1o. Die getrennten Flüssigkeitsstrahler, die in diesen Raum
durch die Offnungen 2o einfließen, führen zu einer sehr starken
Wirbelbewegung der Flüssigkeit bei dessen Durchfließen
durch den Ringraum in Richtung auf das geschlossene Ende des
Gehäuses. Während dieser Bewegung werden alle eventuell vorhandenen schweren Partikel durch die Zentrifugalkraft gegen die
Wand des Gehäuses geschleudert und damit vom Flüssigkeitsstrom getrennt, der um das untere Ende der Hülse 17 herum fließt.
Das Ausscheiden dieser schweren Partikel geht in vollständigerer Weise als bei bekannten Filtern vonstatten, die einen einfachen
Spiraleinlauf haben, ohne daß ein Leitring vorgesehen
ist. Die Lebensdauer des Filtereinsatzes wird damit erhöht, da weniger schwere Partikel der Abschleuderung entgehen.During operation, the liquid reaching the hat 12 flows from the outlet 12 into the annular space between the sleeve 17 and the housing 1o. The separate liquid ejectors which flow into this space through the openings 2o lead to a very strong vortex movement of the liquid as it flows through
through the annulus towards the closed end of the
Housing. During this movement, any heavy particles that may be present are counteracted by the centrifugal force
The wall of the housing is thrown and thus separated from the flow of liquid which flows around the lower end of the sleeve 17.
The separation of these heavy particles takes place in a more complete manner than with known filters which have a simple spiral inlet without a guide ring being provided
is. The service life of the filter insert is increased as less heavy particles escape being thrown off.
