Abstract

Eine Ölpumpe (4) eines Verbrennungsmotors liefert Schmutzöl durch einen senkrecht verlaufenden Ölzufuhrkanal (6) in einen Ringkanal (7) eines Ölfilterflansches (2). Von dort strömt das Öl durch den Ölfilter (1) und eine Zentralbohrung (9) in einen Hauptölkanal (15). Da der Ölzufuhrkanal (6) oberhalb der Zentralbohrung (9) in den Ringkanal (7) mündet und der Hauptölkanal (15) oberhalb der Zentralbohrung (9) verläuft, sinkt der Filterölstand bei abgestelltem Motor nicht unter die Höhe des Schmutzöleintrittes in den Ringkanal (7). Ein völliges Entleeren des Ölfilters bei abgestelltem Motor ist somit verhindert und ein schneller Öldruckaufbau bei erneutem Motorstart begünstigt.An oil pump (4) of an internal combustion engine delivers dirty oil through a vertical oil supply channel (6) into an annular channel (7) of an oil filter flange (2). From there, the oil flows through the oil filter (1) and a central bore (9) into a main oil channel (15). Since the oil supply channel (6) opens into the ring channel (7) above the central bore (9) and the main oil channel (15) runs above the central bore (9), the filter oil level does not drop below the level of the dirty oil inlet into the ring channel (7 ). A complete emptying of the oil filter when the engine is switched off is thus prevented and a rapid build-up of oil pressure is encouraged when the engine is started again.

Description

Die Erfindung betrifft eine Vorrichtung zum Reinigen von Schmieröl nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for cleaning lubricating oil according to the preamble of claim 1.

Eine Vorrichtung, bei der das verschmutzte Öl von einer durch den Verbrennungsmotor angetriebenen Pumpe gefördert wird und zunächst durch einen Zufuhrkanal in einen im Ölfilterflansch untergebrachten, ringförmigen Kanal und von dort in das Filtergehäuse strömt, ist aus DE-PS 33 44 568 bekannt.Hierbei entleert sich bei abgestelltem Motor der Reinölraum des Ölfilters über einen in Strömungsrichtung unterhalb des Filters liegenden Kanal. Dadurch wird der Aufbau des nötigen Öldruckes bei dem erneuten Starten des Motors verzögert.
Der Erfindung liegt die Aufgabe zugrunde, das völlige Entleeren des Ölfilters bei abgestelltem Motor zu verhindern.A device in which the contaminated oil is conveyed by a pump driven by the internal combustion engine and first flows through a supply channel into an annular channel accommodated in the oil filter flange and from there into the filter housing is known from DE-PS 33 44 568 When the engine is switched off, the clean oil chamber of the oil filter is located below a channel in the flow direction. This delays the build-up of the necessary oil pressure when the engine is restarted.
The object of the invention is to prevent the oil filter from being completely emptied when the engine is switched off.

Die Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst.The object is achieved with the characterizing features of claim 1.

Um eine solche Vorrichtung in einfacher Weise zu realisieren, ist in weiterer Gestaltung der Erfindung der Ölzufuhrkanal so dicht an den Ringkanal geführt, daß dieser im Bereich des Ölzufuhrkanales eine verringerte Tiefe aufweist. Weiterhin hat der von dem Ringkanal umschlossene Steg einen geringen Abstand von der durch die Flanschanschlußfläche verlaufenden Ebene und der Ölzufuhrkanal ist als zur horizontalen Teilungsebene der Kurbelgehäusehälften senkrechte Bohrung ausgeführt.In order to implement such a device in a simple manner, in a further embodiment of the invention the oil supply channel is guided so close to the ring channel that it has a reduced depth in the area of the oil supply channel. Furthermore, the web enclosed by the annular channel is at a short distance from the plane running through the flange connection surface and the oil supply channel is designed as a bore perpendicular to the horizontal parting plane of the crankcase halves.

Der mit dieser Erfindung erzielbare Vorteil besteht insbesondere darin, daß der Ölstand in dem Filter nach dem Abstellen des Motors trotz einer Filteranordnung deutlich über dem Ölstand der Motorölwanne nicht unter das oberste Niveau der zum Hauptölkanal führenden Zentralbohrung sinkt. Der Ölfilter ist somit ständig mehr als zur Hälfte gefüllt. Ein schneller Öldruckaufbau nach dem Anlassen des Motors ist dadurch gewährleistet. Durch das Heranführen des Ölzufuhrkanales dicht an die Flanschschlußfläche tritt die Bohrung direkt in den Ringkanal, so daß keine weitere Verbindung vom Ölzufuhrkanal zum Ringkanal notwendig ist. Weiterhin ermöglicht diese Anordnung eine materialsparende, gußgerechte Gestaltung des Kurbelgehäuses im Bereich des Ölfilterflansches und das Anbringen der Ölzufuhrkanalbohrung in der gleichen Aufspannung der Kurbelgehäusehälfte, in der die Kurbelgehäusetrennfläche bearbeitet wird. Schließlich reduziert die etwas zurückliegende Stirnfläche des vom Ringkanal umschlossenen Steges die zu bearbeitende Oberfläche der Flanschanschlußfläche.The advantage that can be achieved with this invention is, in particular, that the oil level in the filter after the engine has been switched off does not drop below the top level of the central bore leading to the main oil channel, despite the filter arrangement being clearly above the oil level of the engine oil pan. The oil filter is therefore always more than half full. This ensures a quick build-up of oil pressure after starting the engine. By bringing the oil supply channel close to the flange connection surface, the bore enters the ring channel directly, so that no further connection from the oil supply channel to the ring channel is necessary. Furthermore, this arrangement enables a material-saving, cast-appropriate design of the crankcase in the region of the oil filter flange and the attachment of the oil supply channel bore in the same clamping of the crankcase half in which the crankcase separating surface is machined. Finally, the somewhat back end face of the web enclosed by the ring channel reduces the surface of the flange connection surface to be machined.

Im folgenden wird anhand von Zeichnungen ein Ausführungsbeispiel der Erfindung näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to drawings.

Es zeigt:

  • Fig. 1 einen Schnitt durch eine Brennkraftmaschine mit einer Vorrichtung zum Reinigen von Schmieröl,
  • Fig. 2 einen Schnitt durch einen am Flansch montierten Ölfilter,
  • Fig. 3 einen Schnitt entlang der Linie III-III aus Fig. 2,
  • Fig. 4 einen Schnitt entlang der Linie IV-IV aus Fig. 3.
It shows:
  • 1 shows a section through an internal combustion engine with a device for cleaning lubricating oil,
  • 2 shows a section through an oil filter mounted on the flange,
  • 3 shows a section along the line III-III from FIG. 2,
  • FIG. 4 shows a section along the line IV-IV from FIG. 3.

Ein Ölfilter 1 ist am Filterflansch 2 eines Verbrennungsmotors 3 befestigt. Das von einer Ölpumpe 4 geförderte Schmutzöl strömt durch einen im Kurbelgehäuseoberteil 5 des Verbrennungsmotors 3 angebrachten Ölzufuhrkanal 6 in einen Ringkanal 7 im Filterflansch 2. Das Schmutzöl tritt durch eine Einmündungsstelle 8 aus dem Ölzufuhrkanal 6 in den Ringkanal 7, die aus der Durchdringung des Ringkanals 7 mit der Bohrung für den Ölzufuhrkanal 6 entsteht.
Damit der Ölzufuhrkanal 6 den Ringkanal 7 nicht unterhalb einer Zentralbohrung 9 schneidet, ist die Tiefe des Ringkanals 7 in einem Teil 10 des Filterflansches 2 nahe dem Ölzufuhrkanal 6 verringert. Das Schmutzöl strömt aus dem Ringkanal 7 durch Eintrittsöffnungen 11 in den Ölfilter 1. Dort durchströmt es zunächst einen ringförmigen Schmutzölraum 12, der außen von einem Blechgehäuse 13 und innen durch eine Filterpatrone 14 begrenzt wird. Das Schmutzöl wird in der Filterpatrone 14 gereinigt und tritt anschließend als Reinöl durch die Zentralbohrung 9 in einen Hauptölkanal 15 aus. Der Hauptölkanal 15 versorgt den Verbrennungsmotor 3 mit Reinöl und liegt oberhalb der Zentralbohrung 9. Da die Einmündungsstelle 8 und der Hauptölkanal 15 oberhalb der Zentralbohrung 9 liegen, sinkt der Filterölstand S (Fig. 2) bei abgestelltem Verbrennungsmotor 3 nicht unter die Höhe der Einmündungsstelle 8 in dem Ringkanal 7.An oil filter 1 is attached to the filter flange 2 of an internal combustion engine 3 . The dirty oil delivered by an oil pump 4 flows through an oil supply channel 6 mounted in the crankcase upper part 5 of the internal combustion engine 3 into an annular channel 7 in the filter flange 2 . The dirty oil passes through a junction 8 from the oil supply channel 6 into the ring channel 7 , which arises from the penetration of the ring channel 7 with the bore for the oil supply channel 6 .
Thus, the oil feed passage 6 7 does not intersect the annular channel below a central bore 9, the depth of the annular channel 7 is reduced in a part 10 of the filter flange 2 close to the oil supply passage. 6 The dirty oil flows out of the ring channel 7 through inlet openings 11 into the oil filter 1 . There it first flows through an annular dirty oil chamber 12 which is delimited on the outside by a sheet metal housing 13 and on the inside by a filter cartridge 14 . The dirty oil is cleaned in the filter cartridge 14 and then emerges as pure oil through the central bore 9 into a main oil channel 15 . The main oil channel 15 supplies the internal combustion engine 3 with pure oil and is located above the central bore 9 . Since the junction 8 and the main oil channel 15 are above the central bore 9 , the sinks Filter oil level S (FIG. 2) with the internal combustion engine 3 switched off not below the level of the junction 8 in the ring channel 7 .

Um den Bearbeitungsaufwand am Kurbelgehäuseoberteil 5 gering zu halten, ist dessen Materialstärke im Bereich des Filterflansches 2 soweit erhöht, daß der Ölzufuhrkanal 6 senkrecht zur Kurbelgehäuseteilungsebene als Bohrung hergestellt werden kann.
Eine dem Ölfilter 1 zugewandte Stirnfläche 16 eines vom Ringkanal 7 umschlossenen Steges 17 hat einen geringfügigen Abstand H gegenüber einer Flanschanschlußfläche 18 und verringert dadurch die Größe der für einen öldichten Sitz des Ölfilters 1 zu bearbeitenden Fläche. Weiterhin ermöglicht der Abstand H einen gleichmäßigen Öleintritt durch alle kreisförmig angeordneten Eintrittsöffnungen 11 in den Schmutzölraum 12.In order to keep the machining effort on the crankcase upper part 5 low, its material thickness in the area of the filter flange 2 is increased to such an extent that the oil supply channel 6 can be produced as a bore perpendicular to the plane of the crankcase division.
An end face 16 facing the oil filter 1 of a web 17 enclosed by the annular channel 7 has a slight distance H from a flange connection face 18 and thereby reduces the size of the surface to be machined for an oil-tight fit of the oil filter 1 . Furthermore, the distance H enables a uniform oil entry through all circularly arranged inlet openings 11 into the dirty oil chamber 12 .
