Abstract
The pressure chamber located in the sealing member is sub-divided by webs into a plurality of individual sub-chambers with restrictors between each sub-chamber and the barrier medium supply in order to obtain a uniform adjustment over the entire periphery of the gap between the sealing member and rotating part. Various types of means such as pressure-filled tubes are used to bias the sealing member from within a groove in the stationary part towards the rotatable part.
