Description
Die Erfindung betrifft eine Schmieröleinfülleitung eines Verbrennungsmotors mit einem in deren Einfüllbereich angebrachten Ölnebelabscheider für eine Kurbelraumentlüftung nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a lubricating oil filling line Internal combustion engine with one installed in its filling area Oil mist separator for crankcase ventilation according to the preamble of claim 1.
Eine solche Einrichtung ist aus US 2,354,722 bekannt.Such a device is known from US 2,354,722.
Hiervon ausgehend beschäftigt sich die Erfindung mit dem Problem, eine solche gattungsgemäße Einrichtung für eine kostengünstige Herstellung aus Kunststoff bei gleichzeitiger Optimierung der funktionellen Eigenschaften dieser Einrichtung zu gestalten.Proceeding from this, the invention deals with the Problem, such a generic device for an inexpensive Manufactured from plastic with simultaneous Optimization of the functional properties of this facility to design.
Die erfindungsgemäße Lösung besteht in einer gattungsgemäßen Schmieröleinfülleitung mit den kennzeichnenden Merkmalen des Patentanspruchs 1.The solution according to the invention consists of a generic one Lube oil filling line with the characteristic features of the Claim 1.
Bei dieser Einrichtung kann das Rücklauföl in einen Raum fließen, in dem ein niedrigerer Gasdruck herrscht als in dem Kurbelraumbereich, aus dem der von Öl zu befreiende Ölnebel bei Durchführung der Kurbelraumentlüftung entzogen wird. Die erfindungsgemäße Einrichtung kann durch die Verwendung eines an einer beliebigen Stelle vorzusehenden Überlaufbehälters an dem Ablaufende der Ölrücklaufleitung kompakt bauend ausgebildet werden. Die Schmieröleinfülleitung kann zusammen mit der Rücklaufölleitung, einer Kurbelraumentlüftungsleitung sowie dem Überlaufbehälter als ein einheitlich handhabbares, sogenanntes Modulteil ausgebildet werden, das an einen Verbrennungsmotor anflanschbar ist. Dabei ist der Ölnebelabscheider ein Teil des von der Schmieröleinfülleitung gebildeten Moduls, wobei dieser Ölnebelabscheider einfach trennbar mit der Schmieröleinfülleitung verbunden ist.With this device, the return oil can enter a room flow in which the gas pressure is lower than in that Crankcase area from which the oil mist to be freed from oil when performing the Crankcase ventilation is withdrawn. The device according to the invention can be provided anywhere by using one Overflow tank at the drain end of the oil return line be compactly constructed. The lubricating oil filling line can together with the return oil line, one Crankcase ventilation line and the overflow tank as a uniformly manageable, so-called module part is formed be flanged to an internal combustion engine is. The oil mist separator is part of the Lubricating oil filling line formed module, this oil mist separator easily separable with the lubricating oil filling line connected is.
Daß das aus dem Ölnebelabscheider rücklaufende Öl gegen einen Gasdruck zurückfließen kann, der geringer ist als in dem zu entlüftenden Kurbelraum, ergibt sich aus folgendem.That the returning from the oil mist separator Oil can flow back against a gas pressure that is lower than in the crankcase to be vented, it follows from the following.
Indem die Rücklaufölleitung in der Nähe des Bodens eines im Betrieb von Schmieröl angefüllten Überlaufbehälters endet, besteht eine Flüssigkeitssperre zwischen dem Raum des Ölnebelabscheiders, in dem das Rücklauföl anfällt und demjenigen Raum, aus dem von Öl zu befreiender Ölnebel aus dem Kurbelraum des Verbrennungsmotors entnommen wird. Ein derart an dem Ölnebelabscheider gegebenes Druckgefälle zwischen Einlaßraum für den Ölnebel und Ablaßraum für abgeschiedenes Öl ist für die Funktion eines Ölnebelabscheiders vorteilhaft. Dies gilt insbesondere bei dem Einsatz eines Zyklons als Ölnebelabscheider.By the return oil line near the bottom of an in Operation of the overflow tank filled with lubricating oil ends, there is a liquid barrier between the space of the oil mist separator, in which the return oil accumulates and that Space from which oil mist to be freed from the crankcase of the internal combustion engine is removed. Such a thing pressure drop between inlet space given to the oil mist separator for the oil mist and drain space for separated oil is advantageous for the function of an oil mist separator. This applies in particular when using a cyclone as an oil mist separator.
Für eine einwandfreie Funktion der Einrichtung ist es notwendig, daß der Boden des Überlaufbehälters bei der Betriebslage der Schmieröleinfüllöffnung lotrecht über eine ausreichende Länge unterhalb des Ölnebelabscheiders liegt. Außerdem muß der Überlaufbehälter ein ausreichend großes Volumen aufnehmen können. Die zwei vorgenannten Bedingungen erklären sich wie folgt.For the device to function properly, it is necessary that the bottom of the overflow tank in the operating position the lubricating oil filler opening perpendicularly over a is sufficient length below the oil mist separator. In addition, the overflow tank must have a sufficiently large volume be able to record. The two aforementioned conditions explain themselves as follows.
Ein bestimmter lotrechter Abstand zwischen dem Ölnebelabscheider und dem Boden des Ausgleichbehälters ist erforderlich, damit sich in der Rücklaufölleitung eine dem Überdruck in dem angrenzenden Gasraum entgegenwirkende Flüssigkeitshöhe ausbilden kann, ohne in den Ölnebelabscheider soweit einzudringen, daß dessen Funktion beeinträchtigt wird. Ein ausreichendes Füllvolumen muß der Überlaufbehälter aufweisen, damit ausreichend Flüssigkeit zum gasdruckausgleichenden Aufsteigen in der Rücklaufölleitung zur Verfügung steht. In der Praxis wird der vorgenannte lotrechte Abstand zwischen Ölnebelabscheider und Boden des Überlaufbehälters einerseits und das Füllvolumen dieses Behälters andererseits so ausgelegt, daß in allen Betriebszuständen einerseits gerade noch kein Rücklauföl in den Ölnebelabscheider funktionsbehindernd rückfließen kann bzw. dort aufgestaut wird und daß andererseits für eine maximale Aufsteighöhe des Öles in der Rücklaufleitung jeweils ausreichend Flüssigkeit in dem Überlaufbehälter zur Verfügung steht.A certain vertical distance between the oil mist separator and the bottom of the expansion tank is required so that there is an overpressure in the return oil line counteracting liquid level in the adjacent gas space can train without penetrating so far into the oil mist separator, that its function is impaired. A sufficient one The overflow container must have a filling volume, thus sufficient liquid to balance the gas pressure Rise in the return oil line is available. In In practice, the aforementioned vertical distance between Oil mist separator and bottom of the overflow tank on the one hand and the filling volume of this container, on the other hand, is designed to that in all operating conditions on the one hand just yet no return oil in the oil mist separator prevents the function can flow back or is dammed up there and that on the other hand for a maximum rise of the oil in the return line sufficient liquid in the overflow container is available.
Der Überlaufbehälter ist mit seiner Öffnung vorteilhafterweise derart im Inneren der Schmieröleinfülleitung angeordnet, daß Schmieröl, das in die Schmieröleinfülleitung eingefüllt wird, zwangsläufig den Überlaufbehälter füllen muß. Bei einer solchen Ausführung ist sichergestellt, daß die erfindungsgemäß angestrebte Flüssigkeitssperre bereits bei Inbetriebnahme eines Motors gewährleistet ist.The opening of the overflow container is advantageous arranged in the interior of the lubricating oil filling line, that lubricating oil that is poured into the lubricating oil filler pipe will necessarily have to fill the overflow tank. In such an embodiment it is ensured that the invention desired liquid barrier already at commissioning an engine is guaranteed.
Eine kompakte Bauweise mit Bezug auf die Anbindung des Ölnebelabscheiders an die Schmieröleinfülleitung ergibt sich bei einer Entnahme des Ölnebels durch die Schmieröleinfülleitung durch eine hierfür vorgesehene Verbindungsleitung zwischen dem Ölnebelabscheider und der Schmieröleinfülleitung. Der Anschluß der zuletzt genannten Leitung an die Schmieröleinfülleitung liegt zweckmäßigerweise in direkter Nachbarschaft zu der Rücklaufölleitung. In dem Anschlußbereich der beiden vorgenannten Leitungen ist der Ölnebelabscheider über eine Flanschverbindung mit insbesondere Steckverschlüssen bei seinen Leitungen an der Schmieröleinfülleitung befestigt. A compact design with regard to the connection of the oil mist separator to the lubricating oil fill line when the oil mist is removed through the lubricating oil filling line through a connection line provided for this purpose between the oil mist separator and the lubricating oil filling line. The connection of the last mentioned line to the Lubricating oil filling line is expediently in the direct Neighborhood to the return oil line. In the connection area of the two lines mentioned above is the oil mist separator via a flange connection with in particular plug closures attached to the lines of the lubricating oil filler pipe.
Die Rücklaufölleitung liegt im Innenraum der Schmieröleinfülleitung. Dort kann diese Leitung über eine Steckverbindung trennbar ausgestaltet sein.The return oil line is inside the lubricating oil filling line. This line can be accessed via a Plug connection to be designed separable.
An dem unteren Ende der Rücklaufölleitung, die insbesondere über die vorgenannte Steckverbindung mit einem oberen Teil verbindbar sein kann, ist vorteilhafterweise der Überlaufbehälter fest verbindbar.At the lower end of the return oil line, in particular via the aforementioned connector with an upper part can be connectable, the overflow container is advantageously firmly connectable.
Durch im Bereich des Überlaufbehältes vorgesehene Befestigungsmittel an der Rücklaufölleitung kann diese lösbar an der Schmieröleinfülleitung befestigt sein.By means of fastening means provided in the area of the overflow container this can be detachably attached to the return oil line be attached to the lubricating oil filling line.
Durch die vorbeschriebenen lösbaren Trennverbindungen zwischen den einzelnen Teilen kann das komplette als Modul auszubildende Teil in einfacher Weise als Kunststoffteil hergestellt werden, das über eine Flanschverbindung an dem Verbrennungsmotor anbringbar ist.The above-described releasable separating connections between The individual parts can be completely trained as a module Part made in a simple manner as a plastic part be that via a flange connection on the internal combustion engine is attachable.
