Abstract (en)
[origin: US4793781A] The engagement parts of the external rotor of a single-rotation machine are interconnected in circumferential direction of the rotor by a ring-like web. This allows high rotational speeds around the single axis of rotation of the external rotor without any increase in the size of dead spaces of the machine.
