ABSTRACT:
According to the invention a seal—arranged between a radially inwardly facing outer boundary surface of an annular sealing gap and a radially outwardly facing inner boundary surface of the sealing gap—is characterized by a sealing ring having a sealing surface which bears sealingly against one of the boundary surfaces of the sealing gap and having a pressure surface which on the side of the sealing ring in radially opposite relationship to the sealing surface forms with the other of the boundary surfaces of the sealing gap an intermediate space which is wedge-shaped in cross-section, and a pressure ring which is biased by a biasing means at least at times into the intermediate space against the other of the boundary surfaces of the sealing gap and the pressure surface for pressing the sealing surface against the one boundary surface of the sealing gap.
