ABSTRACT:
A device for sealing surfaces defined between a collar of a motor shaft and a motor cover comprises a pre-stressed sealing ring mounted at the surfaces which extend at right angles relative to each other, a viscous elastic element for prestressing the sealing ring, and a guide ring positioned between the elastic element and the sealing ring. The sealing ring is positioned between the surfaces to be sealed and is pressed by the guide ring which is displaceable by a pressure medium.
