Abstract (en)
[origin: EP0197238A2] 1. Housing of a turbomolecular vacuum pump with a connection flange (3) of a material which is a good thermal conductor, e.g. aluminium, and a housing shell (1), characterized in that the housing shell (1) at least in the area (1', 4) adjoining the connection flange (3) is so formed that the thermal conductivity in this area is so much reduced relative to the thermal conductivity of the connection flange that undesirably strong heating of the housing shell during the baking out of a receiver connected to the connection flange is avoided.
