Beschreibung
Zusammenfassung:	A rotary piston pump has at least two rotors ( 8 ) with associated drive shafts ( 26 ), wherein for each rotor ( 8 ) an associated bearing tube ( 28 ) is provided, which extends into the associated rotor ( 8 ) and through which the associated drive shaft ( 26 ) passes. Between the inside ( 24 ) of each rotor ( 8 ) and the outside of the bearing tube ( 28 ) a first gap ( 64 ) is provided. In operation, the first gap ( 64 ) contains cooling fluid and is part of a cooling fluid circuit.
