A perfection in the hermetic junction devices between two parts in rotation relative to an axis (Machine-translation by Google Translate, not legally binding)

摘要

An improvement in sealing devices between two parts in relative rotation about an axis which comprises an elastic membrane mounted on one of the two parts and having a friction ring pushed elastically so that it tends to engage by rubbing on the another part, essentially characterized by the fact that the rotation connection of this friction ring with the first part is ensured for the driving pairs lower than a certain limit by an elastic member and for the driving pairs exceeding this limit by contact of rigid organs.
