Abstract

A filling opening 12 for filling lubricating oil into an internal-combustion engine is proposed. This filling opening is provided with a closing cover 15 which has a bayonet-type closure. On the outer side of the wall of the filling opening 12 there is arranged an oil separator 22 into which the blow-through gases emerging from the crank case pass and are fed to the induction pipe or to the pure air side of the air filter. The oil collected in the oil separator 22 is returned via a return opening 23, 24 between the oil separator 22 and the filling opening 12. When oil is being poured into the filling opening 12, in order to avoid this oil passing into the oil separator 22 and rising there, so that under some circumstances it can penetrate as far as the pure air side of the air filter, a closing part 25, constructed as a rotary slide valve, is provided inside the filling opening 12, which closing part closes the return opening 23, 24 between the oil separator 22 and the filling opening 12 when the closing cover 15 is removed. This closure would take place in a forced manner by rotation of the closing cover 15 during opening. When the closing cover 15 is closed, the return openings 23, 24 are released. <IMAGE>

Description

Die Erfindung betrifft eine Einfüllöffnung für das Einfüllen von Schmieröl in eine Brennkraftmaschine nach dem Oberbegriff des Hauptanspruchs.The invention relates to a filling opening for filling lubricating oil into an internal combustion engine according to the preamble of the main claim.

Solche Einfüllöffnungen sind zweckmäßigerweise auf dem Ventilkammerdeckel angeordnet und bestehen in der Regel aus einem rohrfömrigen Einfüllstutzen, der mit einem Deckel mit Renkverschluß verschlossen wird.Such filler openings are expediently arranged on the valve chamber cover and generally consist of a tubular filler neck which is closed with a lid with a bayonet lock.

Es ist ferner bekannt, die im Kurbelgehäuse sich bildenden Durchblasgase über einen Ölabscheider dem Saugrohr oder der Reinluftseite des Luftfilters zuzuführen. Das in dem Ölabscheider angesammelte Öl soll dem Ölkreislauf wieder zugeführt werden. Es hat sich deshalb als zweckmäßig erwiesen, den Ölabscheider, der das im Durchblasgas enthaltene Öl absondert, unmittelbar an der Einfüllöffnung anzuordnen und eine Verbindung zwischen Ölabscheider und Einfüllöffnung herzustellen, so daß das abgeschiedene Öl in die Ventilkammer zurückfließen kann. Es hat sich jedoch gezeigt, daß beim Einfüllen von Öl in die Einfüllöffnung insbesondere dann, wenn in kurzer Zeit sehr hohe Mengen Öl eingefüllt werden, die Gefahr besteht, daß dieses Öl in den Ölabscheider eindringt und unter Umständen in die Verbindungsleitung vom Ölabscheider zu dem Saugrohr bzw. zu der Reinluftseite des Filters gelangt. Die Folge davon wäre das Unbrauchbarmachen der Luftfilterpatrone durch das einfließende Öl.It is also known to supply the blow-by gases which form in the crankcase via an oil separator to the intake manifold or the clean air side of the air filter. The oil collected in the oil separator should be returned to the oil circuit. It has therefore proven to be advantageous to arrange the oil separator, which separates the oil contained in the blow-by gas, directly at the filler opening and to establish a connection between the oil separator and filler opening, so that the separated oil can flow back into the valve chamber. However, it has been shown that when filling oil into the filler opening, particularly if very large amounts of oil are filled in a short time, there is a risk that this oil will penetrate into the oil separator and possibly into the connecting line from the oil separator to the suction pipe respectively. reaches the clean air side of the filter. The consequence of this would be to make the air filter cartridge unusable by the inflowing oil.

Der Erfindung liegt deshalb die Aufgabe zugrunde, diesen Nachteil zu vermeiden, d.h. den Öleinfüllstutzen derart zu gestalten, daß ein Zurückfließen des Öls in den Ölabscheider wirksam verhindert wird.The object of the invention is therefore to avoid this disadvantage, i.e. to design the oil filler neck in such a way that it prevents the oil from flowing back into the oil separator.

Diese Aufgabe wird ausgehend von der obengenannten Gattung durch die kennzeichnenden Merkmale des Hauptanspruchs gelöst.This object is achieved on the basis of the type mentioned above by the characterizing features of the main claim.

Ein wesentlicher Vorteil der Erfindung besteht darin, daß beim Einfüllen von Öl keine zusätzlichen Maßnahmen erforderlich sind, wie beispielsweise das Schließen eines Ventils, sondern daß die wirksame Abdichtung der Rücklauföffnung des Ölabscheiders gegenüber der Einfüllöffnung mit dem Öffnen der Einfüllöffnung zwangsweise vorgenommen wird und damit eine Fehlbedienung ausgeschlossen ist. Ebenso erfolgt die Freigabe der Rücklauföffnung ohne das Erfordernis zusätzlicher Handgriffe, so daß in jedem Fall gewährleistet ist, daß bei einer verschlossenen Einfüllöffnung das in dem Ölabscheider gesammelte Öl ungehindert in die Ventilkammer zurückfließen kann.A major advantage of the invention is that no additional measures are required when filling oil, such as closing a valve, but that the effective sealing of the return opening of the oil separator against the fill opening is forced upon opening the fill opening and thus incorrect operation is excluded. Likewise, the release of the return opening takes place without the need for additional handles, so that it is guaranteed in any case that with a closed fill opening the oil collected in the oil separator can flow back into the valve chamber unhindered.

Es ist weiterhin von Vorteil, daß das als Drehschieber ausgebildete Verschlußteil nur einen sehr geringen Platzbedarf erfordert und damit das Einfüllen des Öls durch dieses Verschlußteil nicht behindert wird.It is furthermore advantageous that the closure part designed as a rotary slide valve requires only a very small amount of space and thus the filling of the oil is not hindered by this closure part.

Gemäß einer Weiterbildung der Erfindung ist vorgesehen, den Ölabscheider ringförmig um die Einfüllöffnung anzuordnen, wobei mehrere Rücklauföffnungen vorgesehen sind. Das Verschlußteil ist dann zweckmäßigerweise als eine Hülse ausgebildet, die eine dünne Wandstärke aufweist und an der Wandinnenseite der Einfüllöffnung anliegt. Diese Hülse ist mit Durchbrüchen versehen, die die Rücklauföffnungen freigeben. Eine solche Hülse läßt sich bei der Montage der Einfüllöffnung in einfacher Weise einlegen. Durch einen Flansch am unteren Rand bleibt das Verschlußteil in dieser Einbaulage fixiert.According to a development of the invention, it is provided that the oil separator is arranged in a ring around the filler opening, with several return openings being provided. The closure part is then expediently designed as a sleeve which has a thin wall thickness has and lies against the inside of the wall of the filler opening. This sleeve is provided with openings that open the return openings. Such a sleeve can be inserted in a simple manner during assembly of the filler opening. The closure part remains fixed in this installation position by means of a flange at the lower edge.

Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung besteht die Wirkverbindung zwischen dem Verschlußdeckel und dem Verschlußteil aus einer formschlüssigen, lösbaren Verbindung, die an dem Verschlußteil durch eine stegförmige Nase gebildet wird, über welche eine an dem Verschlußdeckel angeordnete Mitnehmergabel greift. Selbstverständlich besteht die Möglichkeit, andere Arten von Wirkverbindungen vorzusehen. Denkbar wäre auch die Anordnung eines Stiftes, welcher in eine Bohrung eingreift. Wesentlich bei solchen Ausgestaltungen ist, daß die Drehbewegung des Verschlußdeckels auf das Verschlußteil übertragen wird.According to a further advantageous embodiment of the invention, the operative connection between the closure lid and the closure part consists of a positive, releasable connection which is formed on the closure part by a web-shaped nose, via which a driving fork arranged on the closure lid engages. Of course, there is the possibility of providing other types of active connections. The arrangement of a pin which engages in a bore would also be conceivable. It is essential in such configurations that the rotary movement of the closure cover is transmitted to the closure part.

Weiterbildungsgemäß ist zur Vermeidung einer unbeabsichtigten Drehbewegung das Verschlußteil mit Nocken versehen, die jeweils in den Stellungen, in welchen der Ölbabscheider geschlossen oder offen ist, in Vertiefungen einrasten. Diese Nocken können z.B. in der Ebene der Rücklauföffnungen angeordnet sein und in der geschlossenen Stellung in die Rücklauföffnungen einrasten.According to a further development, in order to avoid an unintentional rotary movement, the closure part is provided with cams which engage in recesses in the positions in which the oil separator is closed or open. These cams can e.g. be arranged in the plane of the return openings and engage in the return openings in the closed position.

Es hat sich weiterhin als vorteilhaft erwiesen, das Verschlußteil mit einem siebförmigen Boden zu versehen, sofern die Einfüllöffnung nicht selbst mit einem solchen Boden ausgestattet ist. Dieser Boden dient zum Schutz der Ventilkammer gegen das Eindringen von festen Gegenständen.It has also proven to be advantageous to provide the closure part with a sieve-shaped bottom, provided that the filling opening is not itself equipped with such a bottom. This floor serves to protect the valve chamber against the penetration of solid objects.

Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen näher erläutert. Gleiche Teile sind mit gleichen Bezugsziffern versehen.The invention is explained in more detail below on the basis of exemplary embodiments. The same parts are provided with the same reference numbers.

  • Figure 1 shows a filler opening with an oil separator
  • Figure 1a is a sectional view of Figure 1
  • Figure 1b, c, the operation of the closure part
  • Figure 2 shows a variant of the closure part shown in Figure 1

In Figur 1 ist der obere Teil eines Ventilkammerdeckels 10 dargestellt. Auf diesem Ventilkammerdeckel ist ein Gehäuse 11 befestigt, welches eine Einfüllöffnung 12 umschließt. Zwischen dem Gehäuse 11 und dem Ventilkammerdeckel ist ein Dichtring 13 vorgesehen. Die Einfüllöffnung 12 ist rohrförmig ausgebildet und weist ein Innenteil 13 auf, welches mit dem Gehäuse 11 an der Schweißnaht 14 verschweißt ist. Beide Teile sind Kunststofformteile.In Figure 1, the upper part of a valve chamber cover 10 is shown. On this valve chamber cover, a housing 11 is fastened, which encloses a filling opening 12. A sealing ring 13 is provided between the housing 11 and the valve chamber cover. The filling opening 12 is tubular and has an inner part 13 which is welded to the housing 11 at the weld seam 14. Both parts are molded plastic parts.

Die Einfüllöffnung 12 ist mit einem Verschlußdeckel 15 verschließbar. Dieser Verschlußdeckel weist einen üblichen Renkverschluß auf. Das Gehäuse 11 ist mit einem Grobgitter 16 versehen. Durch dieses Grobgitter werden Gegenstände, die unbeabsichtigt in die Einfüllöffnung gelangen, zurückgehalten. Ringförmig um die Einfüllöffnung herum befindet sich zwischen dem Gehäuse 11 und dem Innenteil 13 ein Hohlraum 17, welcher die Funktion eines Ölabscheiders hat. Der Ölabscheider ist mit einem ersten Anschlußstutzen 19 versehen. Dieser Anschlußstutzen ist über eine Schlauchverbindung mit dem Kurbelgehäuse verbunden. Die im Kurbelgehäuse sich bildenden Durchblasgase werden über diesen Anschlußstutzen 19 dem Ölabscheider zugeführt. Ein Prallgitter 18 dient zur besseren Entölung der Durchblasgase. Dieses Prallgitter 18 ist ringförmig ausgebildet und an dem Innenteil 13 angeordnet. Im oberen Bereich des Ölabscheiders befinden sich zwei weitere Anschlußstutzen 20, 21. Durch diese beiden Anschlußstutzen tritt das Durchblasgas aus und wird entweder zum Saugrohr über den Anschlußstutzen 20 oder zur Reinluftseite des Luftfilters über den Anschlußstutzen 21 geführt. Bei geschlossener oder wenig geöffneter Drosselklappe werden die Durchblasgase aufgrund des höheren Unterdrucks im Saugrohr über den Anschlußstutzen 20 dem Motor zugeführt. Bei geöffneter Drosselklappe gelangen die Durchblasgase aufgrund des höheren Unterdrucks auf der Filterreinluftseite über den Anschlußstutzen 21 in den Ansaugluftbereich. Das im Ölabscheider 22 gesammelte Öl fließt über Öffnungen 23, 24 in die Ventilkammer zurück.The filling opening 12 can be closed with a closure cap 15. This cover has a conventional bayonet lock. The housing 11 is provided with a coarse grid 16. This coarse grille retains objects that unintentionally get into the filling opening. A cavity 17, which has the function of an oil separator, is located in a ring around the filling opening between the housing 11 and the inner part 13. The oil separator is provided with a first connection piece 19. This connecting piece is connected to the crankcase via a hose connection. The ones in the crankcase themselves Blow-by gases are supplied to the oil separator via this connecting piece 19. A baffle 18 serves to better de-oil the blow-by gases. This baffle 18 is annular and arranged on the inner part 13. In the upper area of the oil separator there are two further connecting pieces 20, 21. The blow-by gas emerges through these two connecting pieces and is led either to the suction pipe via the connecting piece 20 or to the clean air side of the air filter via the connecting piece 21. When the throttle valve is closed or not very open, the blow-by gases are fed to the engine via the connecting piece 20 due to the higher negative pressure in the intake manifold. When the throttle valve is open, the blow-by gases reach the intake air area via the connecting piece 21 due to the higher negative pressure on the filter clean air side. The oil collected in the oil separator 22 flows back into the valve chamber via openings 23, 24.

Wird über die Einfüllöffnung 12 Schmieröl eingefüllt, dann besteht bei einem raschen Einfüllen sehr hoher Mengen die Gefahr, daß das Öl sich in der Einfüllöffnung 12 zurückstaut und damit auch über die Öffnungen 23, 24 ein Rückstau in den Ölabscheider 22 hinein erfolgt. Dieses in den Ölabscheider 22 gelangte Öl kann dort u.U. hochsteigen und durch die Anschlußstutzen 20, 21 zum Saugrohr bzw. zur Reinluftseite des Luftfilters gelangen. Um das Einfließen des Schmieröls in den Ölabscheider 22 zu vermeiden, werden die Öffnungen 23, 24 beim Öffnen des Verschlußdeckels 15 verschlossen. Dies erfolgt über ein Verschlußteil 25. Das Verschlußteil ist ein zylindrischer Hohlkörper, welcher in seinem unteren Bereich mit den Öffnungen 23, 24 fluchtende Öffnungen 26, 27 aufweist und drehbar innerhalb des Innenteils 13 befestigt ist.If lubricating oil is poured in via the filler opening 12, there is a risk that the oil will back up in the filler opening 12 when the filler 12 is poured in very rapidly and thus also backflow into the oil separator 22 via the openings 23, 24. This oil that has entered the oil separator 22 can possibly rise there and reach the suction pipe or the clean air side of the air filter through the connecting pieces 20, 21. In order to prevent the lubricating oil from flowing into the oil separator 22, the openings 23, 24 are closed when the closure cover 15 is opened. This takes place via a closure part 25. The closure part is a cylindrical hollow body which has openings 26, 27 aligned in its lower region with the openings 23, 24 and is rotatably fastened within the inner part 13.

Das Verschlußteil 25 wird vor dem Verschweißen des Gehäuses 11 mit dem Innenteil 13 in das Gehäuse 11 eingelegt und ist nach dem Verschweißen durch den Flanschansatz 28 fixiert. Ein Flanschansatz 28 verhindert ein axiales Verschieben des Verschlußteiles 25.The closure part 25 is inserted into the housing 11 before the housing 11 is welded to the inner part 13 and is fixed by the flange shoulder 28 after the welding. A flange shoulder 28 prevents the closure part 25 from moving axially.

Zum Verschließen der Öffnungen 23, 24 wird das Verschlußteil 25 gedreht. Diese Drehbewegung erfolgt zwangsgeführt über den Verschlußdeckel 15. Hierzu befindet sich an dem Verschlußteil 25 ein Steg 29 (Fig. 1a). Dieser Steg wird von einer Mitnehmergabel 30, welche an dem Verschlußdeckel 15 angebracht ist, umfaßt, sodaß die Drehbewegung des Verschlußdeckels 15 unmittelbar auf das Verschlußteil 25 übertragen wird. Bei geschlossenem Verschlußdeckel 15 befindet sich das Verschlußteil 25 in der in Figur 1b gezeigten Stellung, d.h. die Öffnungen 23, 24 sind aufgrund der fluchtenden Stellung den Öffnungen 26, 27 frei. Das in dem Ölabscheider gesammelte Öl kann ungehindert ablaufen. Wird der Verschlußdeckel 15 geöffnet, so erfolgt dies durch eine 90 Grad-Drehung des Verschlußdeckels 15. Diese Drehung bewirkt das Verschließen der Öffnnungen 23, 24, so daß beim Einfüllen ein Rückstau des Öls in den Ölabscheider 22 nicht erfolgen kann.To close the openings 23, 24, the closure part 25 is rotated. This rotary movement takes place in a positively guided manner via the closure cover 15. For this purpose there is a web 29 on the closure part 25 (FIG. 1a). This web is surrounded by a driving fork 30, which is attached to the closure cap 15, so that the rotational movement of the closure cap 15 is transmitted directly to the closure part 25. When the closure cover 15 is closed, the closure part 25 is in the position shown in FIG. the openings 23, 24 are free due to the aligned position of the openings 26, 27. The oil collected in the oil separator can run off unhindered. If the cap 15 is opened, this is done by rotating the cap 15 by 90 degrees. This rotation closes the openings 23, 24, so that when the oil is poured back into the oil separator 22, the oil cannot backflow.

Zur Vermeidung einer unbeabsichtigen Drehbewegung des Verschlußteils 25 bei geöffnetem Verschlußdeckel 15 sind, wie in Figur 1c gezeigt, an dem Verschlußteil 25 in der Ebene der Öffnungen 23, 24 Nocken 31, 32 vorgesehen. Diese Nocken ragen in der Verschlußstellung in die Öffnungen 23, 24. Damit ist gewährleistet, daß beim Aufsetzen des Verschlußdeckels auf die Einfüllöffnung die Mitnehmergabel 30 über den Steg 29 zu liegen kommt und eine Mitnahme des Verschlußteils 25 durch die Verschlußdeckeldrehung erfolgt.To prevent an unintentional rotary movement of the closure part 25 when the closure lid 15 is open, cams 31, 32 are provided on the closure part 25 in the plane of the openings 23, 24, as shown in FIG. 1c. These cams protrude into the openings 23, 24 in the closed position. This ensures that when the closure lid is placed on the filler opening, the driving fork 30 comes to rest over the web 29 and the closure part 25 is carried along by the rotation of the closure lid.

Eine Variante des Verschlußteils 25 ist in Figur 2 gezeigt. Auch hier befindet sich der Ölabscheider wie in Figur 1 gezeigt unmittelbar an der Einfüllöffnung 12. In dem Innenteil 13 ist ein flaches Verschlußteil 33 eingesetzt. Dieses Verschlußteil weist ebenfalls einen Flanschansatz 28 zur Vermeidung einer axialen Verschiebung auf. Das flache Verschlußteil liegt unmittelbar auf dem Grobgitter 16 auf und weist einen ebenfalls als Grobgitter ausgebildeten Boden 34 auf. In der Mitte des Bodens 34 ist dieser verstärkt und mit einer vierkantförmigen Öffnung versehen. In diese vierkantförmige Öffnung greift ein Vierkantrohr 36. Dieses Vierkantrohr ist an dem Verschlußdeckel 15 angeordnet und überträgt die Drehbewegung des Verschlußdeckels 15 auf das flache Verschlußteil 33. Die Funktion des flachen Verschlußteils 33 entspricht der Funktion des in Figur 1 gezeigten Verschlußteiles 25.A variant of the closure part 25 is shown in Figure 2. Here, too, the oil separator is located directly at the fill opening 12, as shown in FIG. 1. A flat closure part 33 is inserted in the inner part 13. This closure part also has a flange shoulder 28 to avoid axial displacement. The flat closure part lies directly on the coarse grid 16 and has a base 34, which is also designed as a coarse grid. In the middle of the bottom 34 this is reinforced and provided with a square opening. A square tube 36 engages in this square-shaped opening. This square tube is arranged on the closure cover 15 and transmits the rotary movement of the closure cover 15 to the flat closure part 33. The function of the flat closure part 33 corresponds to the function of the closure part 25 shown in FIG. 1.

Selbstverständlich besteht auch die Möglichkeit, andere Arten von Übertragungsmittel vorzusehen, welche die Bewegung des Verschlußdeckels auf ein Verschlußteil übertragen. Möglich wäre z.B. auch die axiale Bewegung des Verschlußdeckels 15 zum Öffnen und Schließen des Ölabscheiders zu benutzen. Hierzu ist lediglich ein geeignetes Übertragungselement erforderlich.

Of course, there is also the possibility of providing other types of transmission means which transmit the movement of the closure cover to a closure part. For example, it would also be possible to use the axial movement of the closure cover 15 to open and close the oil separator. All that is required is a suitable transmission element.
