ABSTRACT:
This invention relates to lip seals for shafts, whose lip bodies consist of rubber elastic material, and is mounted on the reverse side on an essentially radial surface of a back-up ring which is integral with the housing. When the pressure of the medium to be sealed out increases, dangerous overloads occur on the lip edge, in spite of the roller diaphragm-like deformation of the lip body. According to the invention, these overloads are reduced by the introduction of a trough in the supporting back-up ring in the zone of the lip body near the clamp, into which the lip body is deformed and thus the pressure on the edge of the lip is reduced (FIG. 1 ).
