Abstract
a. Turbine de pompe turbomoléculaire. b. Cette pompe turbomoléculaire comprend un rotor 1 de turbine intérieur qui porte des aubes 2 de rotor formant des couronnes et qui, pour fournir l'effet d'aspiration, tournent autour d'un axe 3 à une vitesse élevée par rapport à des aubes 5 de stator montées fixes dans le carter 4 de la pompe. Les aubes 2 de rotor de chaque couronne sont des constituants de disques 6 rotoriques qui sont fixés au rotor entre des bagues 7 d'entretoisement serrées sur le rotor. c. Industrie chimique.
