Abstract
Description
Die Erfindung betrifft einen Zentrifugal-Ölnebelabscheider in einem Verbrennungsmotor nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a centrifugal oil mist separator in an internal combustion engine according to the preamble of claim 1.
Ein
solcher Ölnebelabscheider
ist aus
Die Erfindung beschäftigt sich mit dem Problem, einen gattungsgemäßen Ölnebelabscheider konstruktiv zu vereinfachen und dabei gleichzeitig den in einem Verbrennungsmotor für einen solchen Ölnebelabscheider zusätzlich zu den anderen Bauteilen benötigten Bauraum möglichst gering zu halten.The Invention busy with the problem, a generic Ölnebelabscheider constructive to simplify and at the same time in an internal combustion engine for one such oil mist separator additionally needed to the other components Space as possible to keep low.
Gelöst wird dieses Problem bei einem gattungsgemäßen Ölnebelabscheider durch eine Ausbildung nach dem kennzeichnenden Merkmal des Patentanspruchs 1.Is solved This problem in a generic oil mist by a Training according to the characterizing feature of the claim 1.
Vorteilhafte und zweckmäßige Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.advantageous and appropriate embodiments The invention are the subject of the dependent claims.
Dabei können als erfindungsgemäße Hohlwelle besonders vorteilhaft in einem Verbrennungsmotor beispielsweise dienen, die Nocken-, Kurbel- oder eine Massen – beziehungsweise Schwingungsausgleichswelle, wenn diese Wellen jeweils zumindest auf einer Teillänge hohl ausgebildet sind.there can as a hollow shaft according to the invention particularly advantageous in an internal combustion engine, for example serve, the cam, crankshaft or a mass or vibration balance shaft, if these waves are hollow at least on a partial length are formed.
Die Erfindung beruht auf dem allgemeinen Gedanken, einen gattungsgemäßen Ölnebelabscheider möglichst vollständig in den zentralen Hohlraum einer motorbetriebenen Hohlwelle zu integrieren. Als derartige motorbetriebene Hohlwelle ist dabei in erster Linie gedacht an die Nocken- oder Kurbelwelle eines Motors. Der Ölnebeleintritt kann jeweils im Bereich des einen und der Austritt der voneinander getrennten Bestandteile Öl und Luft in dem Bereich des zweiten Endes erfolgen. Luftein- und Austritt erfolgen zweckmäßigerweise jeweils axial, wobei auch ein radialer Eintritt selbstverständlich möglich ist. Der Ölaustritt erfolgt bevorzugt radial unter der Wirkung der auftrennenden Zentrifugalkraft. Im Inneren der Hohlwelle können entlang des Strömungsweges abscheidewirksame Schikanen vorgesehen sein. Dabei können Schikanen unterschiedlicher Wirkung und unterschiedlichen Aufbaus in Reihe hintereinander angeordnet sein.The The invention is based on the general idea of a generic oil mist separator preferably Completely to integrate into the central cavity of a motor-driven hollow shaft. As such motor-driven hollow shaft is in the first place thought of the cam or crankshaft of an engine. The oil mist entry can each be in the area of one and the exit of each other separated ingredients oil and air in the region of the second end. Air intake and Exit take place expediently each axial, with a radial entry is of course possible. The oil outlet is preferably carried out radially under the effect of separating centrifugal force. Inside the hollow shaft can along the flow path Abscheidewirksame harassment be provided. This can be harassment different effect and different structure in series be arranged one behind the other.
Um bei abgestelltem Verbrennungsmotor das Austreten von Schmauchgasen aus dem Ölnebelabscheider gegenüber Atmosphäre sicher verhindern zu können, ist stromauf des Gasaustrittes der Einbau eines Fliehkraftventiles möglich, das lediglich bei rotierender Hohlwelle einen Gasaustritt zulässt.Around When the internal combustion engine is switched off, the emission of smoke gases from the oil mist separator across from the atmosphere safe to prevent upstream of the gas outlet is the installation of a centrifugal valve possible, that allows gas to escape only when the hollow shaft is rotating.
Ein nachfolgend noch näher erläutertes Ausführungsbeispiel ist im wesentlichen schematisch dargestellt in der einzigenOne in the following even closer Illustrated embodiment is shown substantially schematically in the single
Von der Nockenwelle ist lediglich ein axialer Teilabschnitt dargestellt und insbesondere ohne Antriebs- und Lagerelementen sowie Nocken.From the camshaft is shown only an axial portion and in particular without drive and bearing elements and cams.
