Abstract
A sealing assembly which can be interposed between two relatively movable members to make a seal between the cavity lying between the said members and the exterior environment, composed of two annular elements each of which is firmly connected to one of the said members and on one of which are formed two sliding surfaces perpendicular to one another. The prinipal characteristic of the sealing assembly lies in the fact that it includes an annular sealing element having a sleeve-like lip on which is mounted a resilient element and radially from which extends an annular projection which can slide on one of the sliding surfaces, and a root zone from which extends a second lip independent of and substantially parallel to the first lip and able to slide on the other of the sliding surfaces.
