Abstract
Diese Luftabscheidungsvorrichtung ist im Zusammenhang mit einem Luft-/Ölgemisch wirksam, das bei der Schmierölversorgung von Bauteilen bspw. einer Brennkraftmaschine entsteht, welche Luftabscheidungsvorrichtung mittels eines Zentrifugalabscheiders Luft und Öl voneinander trennt. DOLLAR A Um diese Luftabscheidungsvorrichtung zu optimieren, umfasst der Zentrifugalabscheider einen ringförmigen Rotorkörper aus einem durchlässigen Werkstoff, wobei das besagte Luft-/Ölgemisch einem vom Rotorkörper begrenzten, ein Zentrum des Rotorkörpers umgebenden ersten inneren Raum zugeführt wird, von wo aus das Öl durch Rotation des Rotorkörpers von einer inneren Oberfläche über eine äußere Oberfläche des Rotationskörpers in einen zweiten äußeren Raum gelangt und die Luft über eine mit dem ersten Raum verbundene Luftrückführungsleitung entweicht.This air separation device is effective in connection with an air / oil mixture that arises during the supply of lubricating oil to components, for example an internal combustion engine, which air separation device separates air and oil from one another by means of a centrifugal separator. DOLLAR A In order to optimize this air separation device, the centrifugal separator comprises an annular rotor body made of a permeable material, said air / oil mixture being supplied to a first inner space bounded by the rotor body and surrounding a center of the rotor body, from where the oil is fed by rotation of the Rotor body reaches a second outer space from an inner surface via an outer surface of the rotating body and the air escapes via an air return line connected to the first space.
Description
Die Erfindung bezieht sich auf eine Luftabscheidungsvorrichtung für ein Luft-/Ölgemisch, das bei der Schmierölversorgung von Bauteilen bspw. einer Brennkraftmaschine entsteht nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to an air separation device for an air / oil mixture, that at the lubricating oil supply of components eg. An internal combustion engine is created according to the preamble of claim 1
Um die Funktionsfähigkeit von mit Schmieröl versorgten Bauteilen bei Brennkraftmaschinen zu gewährleisten, ist der Luftgehalt im Schmieröl innerhalb definierter Grenze zu halten. In diesem Zusammenhang hat sich herausgestellt, dass ein relativ großer Anteil des Luftgehalts im Schmieröl bei Brennkraftmaschinen mit Trockensumpfschmierung und/oder Ölrückförderpumpen durch den Absaugvorgang in das Schmieröl eingebracht wird. Die Ölrückförderpumpen sind auf eine größtmögliche Schmierölmenge ausgelegt und fördern in einer Reihe von Betriebsbedingungen der jeweiligen Brennkraftmaschine ein Luft-/Ölgemisch in den Schmieröltank bzw. Ölsumpf.Around the functionality of lubricated oil To ensure components in internal combustion engines, the air content in the lubricating oil within a defined limit. In this context has It turned out that a relatively large proportion of the air content in the lubricating oil in internal combustion engines with dry sump lubrication and / or oil return pumps is introduced by the suction in the lubricating oil. The oil return pumps are designed for the largest possible amount of lubricating oil and promote in a number of operating conditions of the respective internal combustion engine an air / oil mixture in the oil tank or oil sump.

der
Aufgabe der Erfindung ist es, eine Luftabscheidungsvorrichtung für ein Luft-/Ölgemisch zu schaffen, der im Aufbau einfach ist und sich durch gute Funktion auszeichnet.task The invention is an air separation device for an air / oil mixture to create, which is simple in construction and by good function distinguished.
Diese Erfindung wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere, die Erfindung ausgestaltende Merkmale sind in den Unteransprüchen enthalten.These Invention is solved by the features of claim 1. Further, the invention ausgestaltende features are included in the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteil sind darin zu sehen, dass durch den aus durchlässigem Werkstoff bestehenden Rotorkörper der Luftabscheidungsvorrichtung eine funktionsgerechte Trennung der Luft aus dem bei der Schmierölversorgung für Brennkraftmaschinenbauteile sich ergebenden Luft-/Ölgemisch erfolgt. Dass der Rotorkörper aus porösem Werkstoff bzw. Sintermaterial besteht, unterstützt die Wirkung des Rotorkörpers, der ja das Öl vom ersten inneren Raum in den zweiten äußeren Raum fördert, wobei über den ersten inneren Raum die abgeschiedene Luft gezielt in eine Entlüftungsleitung abgeführt wird. Um den Rotorkörper günstig unterbringen zu können ist ein Gehäuse mit rotationssymmetrischer Gestalt vorgesehen, in welchem Gehäuse sich auch der erste innere Raum und der zweite äußere Raum auf einfache Weise integrieren lassen. Schließlich trägt die Verbindung der Luftabscheidungsvorrichtung mit einer Ölpumpe zu einer konstruktiven Lösung bei, die sich bei übersichtlicher Bauweise leicht verwirklichen lässt.The with the invention mainly achieved advantage can be seen in that by the permeable material existing rotor body of Luftabscheidungsvorrichtung a functionally appropriate separation of Air from the at the lubricating oil supply for internal combustion engine components resulting air / oil mixture he follows. That the rotor body made of porous Material or sintered material, supports the effect of the rotor body, the yes the oil from the first inner space into the second outer space promotes, passing over the first inner space the separated air targeted into a vent line dissipated becomes. To the rotor body Cheap to be able to accommodate is a housing with rotationally symmetrical shape provided in which housing itself also the first inner space and the second outer space in a simple way integrate. After all wears the Connection of the air separation device with an oil pump to a constructive solution at, which is clearer Easy to realize construction.
