TURBOMOLECULAR VACUUM PUMP
A turbomolecular vacuum pump comprises a hollow stator (1) in which is mounted a hollow rotor (3) between which are located channels (3, 4) of the turbomolecular and molecular gas-pumping stages connected to the atmosphere through additional and main dynamic sealing channels (34, 36) formed by groov...
