Abstract (en)

[origin: US6457954B1] A friction vacuum pump (1) with a frame (5), stator (3), rotor (4) and housing; all functional elements of the pump are combined into one unit (22), which, in turn, can be inserted into a housing (19, 55) that has been adapted to a specific application; using this procedure, all separate connection housing can be eliminated and optimal conductance can be achieved (FIG. 1).
