摘要： In a mechanical face seal of the diaphragm bellows type having a face seal ring with a body defining a substantially flat, annular sealing surface, and a holder adapted to be disposed radially about the seal ring in interference fit with a loaded surface of the seal ring, the holder defining a shoulder surface for engaging upon a corresponding shoulder surface of the face seal ring, the holder positioning the seal ring for sealing engagement with an opposed sealing surface of a relatively rotating second seal ring, and the holder defining a loading surface adapted to apply radially inwardly directed contact pressure upon the opposed loaded surface of the face seal ring, the face seal ring and the holder having different coefficients of thermal expansion, contact pressure applied by the holder upon the face seal ring is applied to an area of the face seal ring loaded surface, the resultant of the contact pressure being disposed axially between the sealing surface and the centroid of the face seal ring thereby to cause the sealing surface to lie substantially flat at varying temperatures of operation.
