ABSTRACT:
The invention concerns seals particularly for rotating shafts.
This seal, with a flexible membrane in the form of a cupola having an aperture for the shaft to pass therethrough, is characterized by the fact that said cupola has a thickness decreasing from its base to the contact ridge with the shaft, the elasticity necessary for maintaining the contact being obtained from the inherent rigidity of the membrane.
