Derartige Entlüftungsvorrichtungen sind aus dem Stand der Technik bereits bekannt, wobei die Entlüftung des Kurbelgehäuses in der Regel über eine Leitung in den Ansaugtrakt erfolgt. Es handelt sich dabei um eine durchaus umweltfreundliche Lösung, da das Öl, welches beim Entlüften frei wird, sofort im Verbrennungraum verbrannt wird. Der Nachteil besteht darin, daß bei Motoren mit großer Schräglage, z.B. bei Schiffsmotoren oder umgefallenen Motoren die Gefahr besteht, daß das Öl in den Verbrennungsraum gelangt und der Motor damit "durchgeht" und sich aufgrund von überhöhter Drehzahl selbst zerstört.Such venting devices are from the state already known in the art, the ventilation of the Crankcase usually via a line in the Intake tract takes place. It is a quite environmentally friendly solution because the oil which is released when venting, immediately in the combustion chamber is burned. The disadvantage is that Motors with a large inclined position, e.g. for ship engines or overturned engines there is a risk that the oil gets into the combustion chamber and the engine with it "goes through" and becomes excessive due to excessive Speed destroyed itself.

In Fig. 1 ist das Kurbelgehäuse 1 mit einem
Entlüftungsventil 2, das beispielsweise ein Membranventil
sein kann, verbunden, wobei das Entlüftungsventil
2 mit einem Ölabscheider 3 verbunden ist, der
an seinem einen Ende eine Öffnung 4 zur Atmosphäre
hin aufweist und an seinem anderen Ausgang mit einem
Filter 5 verbunden ist. Das Filter 5 wiederum ist mit
der Saugseite der Ölpumpe 6 verbunden, die wiederum
das Öl aus einem Ölsumpf 7 ansaugt und auf ihrer

Zwischen dem Filter 5 und der Pumpe 6 ist zusätzlich
ein Füllstutzen 8 dargestellt, bei welchem dem System
zusätzlich Öl zugeführt werden kann.In Fig. 1, the
Bei Überdruck im Kurbelgehäuse kann das Gas-Ölgemisch
über das Entlüftungsventil 2 in den dafür
vorgesehenen Leitungskanal 9 entweichen. Im
Ölabscheider 3 wird das Gas dann vom Öl getrennt und
über die Öffnung 4 an die Atmosphäre abgeleitet,
wogegen das Öl von dem als Saugpolster ausgebildeten
Filter 5 aufgesaugt wird. Das so gefilterte Öl
gelangt von dort in eine kleine Kammer, den sog.
Separator 11. Das hier gesammelte Öl wird über die
Ölleitung 10 von der Saugseite der Ölpumpe 6 angesaugt.
Dabei weist die Ölleitung 10 einen Querschnitt
von etwa 0,5 mm auf, der wesentlich kleiner ist als
der Querschnitt der Leitung 9. Wenn nämlich kein Öl
an den Separator anfällt, die Leitung 10 also Luft
zieht, muß die angesaugte Luftmenge so gering
gehalten sein, daß das Schmierölsystem nicht
beeinträchtigt wird (z.B. abreißender Schmierung).
Von der Saugseite der Ölpumpe, die im Normalfall Öl
aus dem Ölsumpf 7 ansaugt, gelangt das Öl in das
Kurbelgehäuse 1. Über den Einfüllstutzen 8 besteht
