Abstract (en)
[origin: EP1096152A2] The turbo molecular pump has rotor discs (10) and stator discs (14) stacked in alternation within a cylindrical pump housing, cooperating for providing a pump effect. Each stator disc has a distance ring (16) which determines the distance between adjacent stator discs, with part (17) of the cylindrical housing forming an integral stator element (12). The rotor discs are attached to a rotor shaft (4) via clamp elements (24).
