verlaufender Wandabschnitt 6 und 8 herausgebildet, die zusammen mit einem an den
Flanschflächen 10 und 12 der beiden Wandabschnitte 6 und 8 befestigten Öldeckel 14
ein Ölauffanggehäuse, im folgenden als Ölwanne bezeichnet, bilden. Die Ölwanne besteht
aus einem Ölabsaugraum 16, in dem ein zu einer nicht dargestellten Hauptölpumpe
führender Ölabsaugschnorchel 17 angeordnet ist. Links und rechts vom Ölabsaugraum
16 sind zwei Ölsammelräume 18 und 20 ausgebildet, die gegenüber dem Ölabsaugraum
16 durch zwei später noch näher beschriebene Ölschottwände 22 und 24 abgetrennt
sind. In den beiden Ölsammelräumen 18 und 20 ist jeweils ein Öl/Luftabscheider, ein
sog. Swirlpot 26 und 28 angeordnet. Zu den beiden Swirlpots 26 und 28 führt jeweils
eine Ölleitung 30 und 32, die an ihren beiden anderen Enden über jeweils ein
Anschlussstück 34 und 36 an zwei durch die Kurbelgehäusehälften 2 und 4 gebildeten
