Abstract
Description
Die Erfindung betrifft ein Ölfilter eines Verbrennungsmotors nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to an oil filter an internal combustion engine according to the preamble of the claim 1.
Ein
solches Ölfilter
ist bekannt aus
Bei einem solchen Filter sind das Haupt- und das Nebenstromfilter jeweils als ein austauschbarer Einsatz ausgebildet. Bei einer Wartung des Filters ist es möglich, dass das Filtergehäuse mit lediglich einem Hauptstrom- und fehlendem Nebenstromfilter geschlossen wird. Bei Motorbetrieb bewirkt ein fehlendes Nebenstromfilter einen den Motorbetrieb beeinträchtigenden Abfall des Öldruckes. Dies ergibt sich daraus, dass bei einer gattungsgemäßen Zentrifuge das zentrifugierte Öl durch Drosselbohrungen in einen drucklosen Raum, der beispielsweise das Motorkurbelgehäuse ist, austritt. Die Drosselbohrungen sind derart angeordnet, dass das Öl tangential um die Lagerachse des Zentrifugeneinsatzes austritt, wodurch die Zentrifuge in Rotation versetzt wird. Damit ein für die Ausübung der Rotation ausreichender Druckabfall an den Drosselbohrungen erhalten bleibt, erfolgt die Ölzufuhr in den Zentrifugeneinsatz ungedrosselt über einen relativ großen Einlassströmungsquerschnitt. Bei in dem Filter fehlendem Zentrifugeneinsatz kann das Öl durch diesen großen Einlassquerschnitt ungehindert durch denjenigen Teil des Filtergehäuses hindurch, in dem an sich der Zentrifugeneinsatz sich befinden sollte, in den drucklosen Raum ungehindert abfließen. Die führt zu einem für einen einwandfreien Motorbetrieb unzulässig hohen Öldruckverlust.at Such a filter is the main and the bypass filter respectively designed as a replaceable insert. During maintenance of the Filters it is possible that the filter housing closed with only one Hauptstrom- and missing bypass filter becomes. When the engine is running, a missing bypass filter will cause a interfering with engine operation Drop in oil pressure. This results from the fact that in a generic centrifuge the centrifuged oil through throttle holes in a non-pressurized space, for example the engine crankcase is, exit. The throttle bores are arranged such that the oil tangentially around the bearing axis of the centrifuge insert, whereby the centrifuge is rotated. Thus one for the exercise of the Sufficient pressure drop is maintained at the throttle bores, the oil supply takes place in the centrifuge insert unthrottled over a relatively large inlet flow area. When missing in the filter centrifuge insert, the oil can through this big one Inlet cross-section unhindered through that part of the filter housing, in which the centrifuge insert should be located, in the unpressurized space flow unhindered. That leads to one for one perfect motor operation inadmissible high oil pressure loss.
Die Erfindung beschäftigt sich mit dem Problem, bei fehlendem Nebenstromfiltereinsatz noch einen funktionsfähigen Betrieb des gattungsgemäßen Ölfilters sicherzustellen.The Invention busy with the problem, in the absence of bypass filter insert another functional Operation of the generic oil filter sure.
Gelöst wird dieses Problem durch eine Ausführung eines gattungsgemäßen Filters nach dem kennzeichnenden Merkmal des Patentanspruchs 1.Is solved this problem by an execution a generic filter according to the characterizing feature of patent claim 1.
Vorteilhafte und zweckmäßige Ausgestaltungen sind Gegenstand der Unteransprüche.advantageous and appropriate embodiments are the subject of the dependent claims.
Die Erfindung beruht auf dem allgemeinen Gedanken, eine Einrichtung vorzusehen, die bei fehlendem Zentrifugeneinsatz zwangsläufig für ein Verschließen der Einlassöffnung sorgt, durch die das Öl bei vorhandenem Zentrifugeneinsatz in dessen Inneres geleitet wird. Diese Einrichtung umfasst ein eine Durchströmung dieser Einlassöffnung sperrendes Sicherheitsventil, das an sich an einer beliebigen Stelle der Zuführleitung angeordnet sein kann. Betätigt kann das Sicherheitsventil mechanisch direkt oder auch indirekt werden. Bei einer indirekten Betätigung kann beispielsweise ein elektrisches Stellventil eingesetzt sein, das die Stellimpulse von einem entfernt liegenden Signalgeber erhält, der das Vorhanden- bzw. Nichtvorhandensein eines Zentrifugeneinsatzes innerhalb des Ölfilters detektieren kann.The The invention is based on the general idea of a device be provided in the absence of centrifuge insert necessarily for closing the inlet port ensures, through which the oil existing centrifuge insert is directed into the interior. This device comprises a flow-through of this inlet opening blocking Safety valve, which in itself at any point of the supply line can be arranged. Can be operated the safety valve mechanically directly or indirectly. In an indirect operation can For example, be used an electric control valve, the receives the control pulses from a remote signal generator, the the presence or absence of a centrifuge insert within of the oil filter can detect.
Bei einer in den Unteransprüchen näher beschriebenen Ausführung des Sicherheitsventiles enthält dieses einen Ventilschieber, dessen Verschiebestellung bestimmt, ob die Einlassöffnung für die Zentrifuge verschlossen oder offen ist. Der Ventilschieber ist in einer ortsfesten Halterung derart verschiebbar gelagert, dass ein in dem Ölfilter vorhandener Zentrifugeneinsatz lediglich eine den Einlass freigebende Verschiebeposition zuläßt. Hierfür sorgt ein in dem Zentrifugeneinsatz entsprechend vorgesehenes, auf den Ventilschieber einwirkendes Widerlager. Bei in dem Ölfilter fehlenden Zentrifugeneinsatz, bei dem das entsprechende Widerlager fehlt, nimmt der Ventilschieber eine einlassverschließende Position ein. Diese verschließende Position kann beispielsweise durch eine Federbeaufschlagung des Ventilschiebers erreicht werden. Im einfachsten Falle wird der Ventilschieber allerdings durch den an diesem anstehenden Öldruck in der Zuleitung in die Verschlussposition bewegt.at one in the subclaims described in more detail execution of the safety valve this one valve spool whose displacement position determines whether the inlet opening for the Centrifuge is closed or open. The valve spool is in a stationary holder so slidably mounted that a in the oil filter existing centrifuge insert only a release position releasing the sliding position allows. This ensures a provided in the centrifuge insert accordingly, on the Valve slide acting abutment. In in the oil filter missing centrifuge insert, in which the corresponding abutment is missing, the valve spool takes a einlassverschließende position one. This occlusive Position can, for example, by a spring loading of the Valve spool can be achieved. In the simplest case, the valve spool However, by the pending on this oil pressure in the supply line in moves the shutter position.
Ein Verschluss der Einlassöffnung muss nicht vollständig sein. Es genügt vielmehr, dass in der Verschlussposition des Ventiles durch dieses nicht ein höherer Ölstrom hindurchtreten kann als bei vorhandenem Zentrifugeneinsatz durch die Zentrifuge als Nebenstromfilter.One Closure of the inlet opening does not have to be complete be. It is sufficient Rather, that in the closed position of the valve through this do not pass a higher oil flow can be considered as existing centrifuge use by the centrifuge as Bypass filters.
Ein besonders vorteilhaftes, weil konstruktiv einfach ausgeführtes Ausführungsbeispiel ist in der Zeichnung dargestellt.One particularly advantageous because structurally simple embodiment executed is shown in the drawing.
