ABSTRACT:
An axially movable seal face member of a rotary mechanical face seal, for example for a ship's stern shaft, is sealed to its associated structure, and at the same time loaded axially, by the wedging action of a ring urged radially between two oppositely inclined annular surfaces on bodies associated with the member and the structure, either the ring or the surfaces or both being of resilient material. The ring could be a rubber O-ring and the surfaces could be two further O-rings. Alternatively the ring could be rigid, or the ring could be resilient but the other two surfaces rigid.
