Abstract (en)
[origin: EP2706237A2] The pump has a gas inlet opening, a gas outlet opening, and a rotor (201) fastened to a rotor shaft (232). The rotor comprises rotating pump-active components and a screw (280) that is arranged at the rotor shaft in an axial direction. A pin (281) is arranged radially or axially in the rotor shaft for inhibiting rotation of the rotor against the rotor shaft, and a projection is formed in the rotor shaft in a radial direction or in an axial direction. The pin stays in engagement with a recess of the rotor shaft. A supporting ring is arranged at a support section.
