Description
Die Erfindung betrifft ein Nebenstromfilter mit einer Zentrifuge gemäß dem Oberbegriff des Anspruches 1.The invention relates to a bypass filter with a centrifuge according to the preamble of
Die
Im Übrigen sind Kombinationen aus Haupt- und Nebenstromfiltern allgemein bekannt. Hierzu wird beispielhaft auf die folgenden Druckschriften verwiesen:
Außerdem zeigt die
Die Erfindung beschäftigt sich mit dem Problem, ein Nebenstromfilter der eingangs angegebenen Art zu schaffen, welches in der Praxis die geforderte betriebliche Lebensdauer gewährleistet und in besonders ökonomischer Weise zur Verfügung gestellt werden kann.The invention is concerned with the problem of creating a bypass filter of the type specified, which ensures the required operational life in practice and can be made available in a particularly economical manner.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Gehäuse des Nebenstromfilters einen als Anschlussbereich des Hauptstromfilters ausgebildeten Bodenbereich aufweist, der im zusammengebauten Zustand von Haupt- und Nebenstromfilter mit einer inneren Ringwand die Außenseite des topfförmigen Hauptstromfiltergehäuses dicht überlappt und zwischen der Außenseite der inneren Ringwand und der Innenseite einer die innere Ringwand umschließenden äußeren Ringwand einen mit dem Innenraum des Nebenstromfilters kommunizierenden Ringkanal aufweist, der seinerseits im zusammengebauten Zustand von Haupt- und Nebenstromfilter mit einem außen am Hauptstromfiltergehäuse angeordneten, zum Ringkanal hin offenen Aufnahmeringkanal und einer davon ausgehenden Ablassleitung kommuniziert.This object is achieved in that the housing of the bypass filter has a trained as a connection region of the main flow filter bottom area, the outer side of the cup-shaped main flow filter housing tightly overlaps in the assembled state of main and bypass filter with an inner annular wall and between the outside of the inner ring wall and the Inside an inner ring wall enclosing the outer annular wall has a communicating with the interior of the bypass filter annular channel which in turn in the assembled state of main and bypass filter communicates with an externally arranged on the main flow filter housing, communicating with the annular channel open receiving ring channel and an outgoing therefrom discharge line.
Das erfindungsgemäße Nebenstromfilter kann also nach Art eines Deckels auf das topfförmige Gehäuse des zugeordneten Hauptstromfilters aufgesetzt werden.The bypass filter according to the invention can therefore be placed in the manner of a lid on the cup-shaped housing of the associated main flow filter.
Dabei beruht die Erfindung auf dem allgemeinen Gedanken, das Nebenstromfilter bei einer erforderlichen Wartung, das heißt nach einer für die Zentrifuge vorgegebenen maximalen Betriebslaufzeit, als Ganzes, das heißt einschließlich des gesamten Gehäuses, auszutauschen. Da der Innenraum des Nebenstromfilters im Falle eines Schmierölfilters mit dem Kurbelraum eines Verbrennungsmotors verbunden ist, können diejenigen Gehäuseteile, die nicht direkt mit dem Innenraum des Hauptstromfilters in Verbindung stehen, aus kostengünstigem Kunststoff mit geringer Wandstärke ausgebildet werden. Lediglich eine an den Innenraum des Hauptstromfilters angrenzende Trennwand des Anschlussbereiches ist dem in dem Hauptstromfilter herrschenden Druck entsprechend stabil auszuführen, was jedoch ebenfalls mit Kunststoff möglich ist. Insgesamt kann damit das gesamte Nebenstromfilter einschließlich der darin gelegenen Lager der Zentrifuge aus zumindest gleichartigem und damit problemlos entsorgbarem Material hergestellt werden. So kann das gesamte Nebenstromfilter insbesondere als bei seiner Entsorgung gemeinsam veraschbares Bauteil ausgeführt werden.The invention is based on the general idea, the bypass filter with a required maintenance, that is, after a predetermined for the centrifuge maximum operating time, as a whole, that is, including the entire housing to exchange. Since the interior of the bypass filter is connected in the case of a lubricating oil filter with the crankcase of an internal combustion engine, those housing parts that are not directly related to the interior of the main flow filter can be made of inexpensive plastic with low wall thickness. Only one adjacent to the interior of the main flow filter partition wall of the connection area is the case correspondingly stable to perform the pressure prevailing in the main flow filter, but this is also possible with plastic. Overall, therefore, the entire bypass filter including the bearings located therein of the centrifuge from at least similar and thus easily disposable material can be produced. Thus, the entire by-pass filter can be designed in particular as a component which can be incinerated together when it is disposed of.
Als im Sinne der Erfindung besonders zweckmäßig ist eine Ausgestaltung des Nebenstromfiltergehäuses dahingehend, dass das gesamte Gehäuse ein verschlossenes, nicht zerstörungsfrei zu öffnendes Bauteil darstellt.As in the context of the invention particularly useful is an embodiment of the bypass filter housing to the effect that the entire housing is a sealed, non-destructive openable component.
Zur Verbindung des Nebenstromfilters mit dem Hauptstromfilter ist das Gehäuse des Nebenstromfilters vorteilhafterweise mit Schraubenverschlußmitteln versehen, die komplementär zu entsprechenden Aufnahmemitteln des Hauptstromfiltergehäuses ausgebildet sind.To connect the bypass filter with the main flow filter, the housing of the bypass filter is advantageously provided with screw closure means which are formed complementary to corresponding receiving means of the main flow filter housing.
An dem Wandbereich des Nebenstromfiltergehäuses, der bei angeschlossenem Hauptstromfilter an das Innere des Hauptstromfilters angrenzt, sind zweckmäßigerweise Haltemittel für den Hauptstromfiltereinsatz vorgesehen. Diese Haltemittel sind bei einer besonders vorteilhaften Ausgestaltung Bestandteil einer Schnappverschlußeinrichtung gegenüber dem Hauptstromfiltereinsatz.At the wall region of the bypass filter housing, which adjoins the interior of the main flow filter when the main flow filter is connected, holding means for the main flow filter insert are expediently provided. These holding means are in a particularly advantageous embodiment part of a snap closure device relative to the main flow filter insert.
Für die Versorgung der Zentrifuge des Nebenstromfilters mit zu reinigender Flüssigkeit empfiehlt sich eine Zufuhrleitung durch den Wandbereich des Nebenstromfiltergehäuses, der an das Innere des Hauptstromfilters angrenzt.For the supply of the centrifuge of the bypass filter with liquid to be cleaned, a supply line through the wall portion of the bypass filter housing adjacent to the interior of the main flow filter is recommended.
Der Abfluss aus dem Nebenstromfilter kann durch eine Wand des Hauptstromfilters hindurch erfolgen.The effluent from the bypass filter may be through a wall of the main flow filter.
Insgesamt ist es vorteilhaft, die Einsätze von Haupt- und Nebenstromfilter achsgleich anzuordnen.Overall, it is advantageous to arrange the inserts of main and secondary flow filters coaxially.
Ein vorteilhaftes, nachstehend noch näher erläutertes Ausführungsbeispiel ist in der Zeichnung dargestellt.An advantageous, explained in more detail below embodiment is shown in the drawing.
