Abstract
A rotary piston engine comprises at least two rotors, a power component and a blocking component, which interact and have spur gearings, the number of teeth of which differs by one, the rotors and an engine housing accommodating the rotors delimiting working compartments. The rotors are twisted at a defined angle to each other. The power component is driven by and rotationally connected to an electric motor arranged on the same axis. The motor has an internal stator and an external rotor, the engine housing being directly connected to the motor. The engine housing has a supporting tube section projecting into and supporting the internal stator. The external rotor has a bell which encloses the internal stator and has a center drive shaft extending through the supporting tube section and rotationally connected to the power component, the drive shaft being mounted towards the inner wall of the supporting tube section.
