Abstract
A sealing ring for sealing about a relatively-rotatable member is an annular, disk-like ring having a root surface about one edge which is adjacent a flarable, sealing-surface zone for slidingly engaging the member. Torsion ribs project from the root surface. The inside surfaces of the torsion ribs are regular prolongations of the sealing surface and the distance therefrom to opposite, outside surfaces diminishes, preferably continuously to a knife-like edge where the inside and outside surfaces meet. The result peels liquid to be sealed in from the relatively-rotating member so that it does not destructively deform the torsion ribs even at high speeds of relative rotation.
