ABSTRACT:
The invention relates to a seal, consisting of an elastomer shaped ring, which is to be pushed onto a cylindrical circumferential surface and supports itself on the latter by a radially acting sealing surface, with an embedded inner ring, consisting of a chamber portion, likewise to be pushed onto the circumferential surface, with a sealing chamber, which surrounds the shaped ring, is undersized relative to the outer contour of the shaped ring and conically widens from the clear inside diameter of the chamber portion toward one face of the chamber portion, and consisting of fastening means which fix the chamber portion with respect to a second surface resting against the face of the chamber portion. For sealing off a cylindrical surface with respect to a second surface standing vertically on the cylindrical axis, it is proposed that the shaped ring have an axially acting sealing surface, preferably lying at right angles to the radially acting sealing surface, for contact with the second surface.
