Abstract

The vacuum pump (1) has a rapidly rotating rotor (2) with attached active pump components (4), a stator (9) with attached active pump components (5) and first and second housing components (10,11). The first and second housing components have mutually overlapping structures at their joint point (13) to provide locking of the components against a movement solely in the axial direction.
