ABSTRACT:
An arrangement for sealing a chamber containing pressure medium against a movable band. The band is arranged to form one side of the chamber. The arrangement comprises a sealing framework which is fastened to a body part of the chamber by means of a resilient membrane. The sealing framework is further provided with a sealing means for providing a sealing effect between the movable band and the rest of the chamber. The sealing means is thereby arranged to be pressed against the band by the pressure effect of a load medium fed on one side of the resilient membrane. In order to obtain an effective and adaptable sealing effect, the means for providing the sealing effect is formed by at least two sealing elements arranged in parallel and between which a sealing liquid is provided.
