- the drive space inside the internal combustion engine is below or behind the mounting flange. In this way, the space required by the separator outside of the internal combustion engine is kept particularly small, resulting in a very compact design.
- the drive space lying in the internal combustion engine can be arranged for example in an engine block or a cylinder head or a cylinder head cover of the internal combustion engine.
- the invention proposes that a first bearing of the shaft is arranged in the base body and a second bearing of the shaft in the lying in the internal combustion engine drive space.
