Abstract (en)
[origin: DE19901340A1] The invention relates to a frictional vacuum pump (1) with a chassis (5), a stator (3), a rotor (4) and a housing. All functional elements of the pump are assembled in a single unit (22) that is in turn inserted into a housing (19, 55) which is adapted to the application. This makes it possible to exclude additional connecting housings and enables optimal conductance situations.
