ABSTRACT:
A sealed cover assembly for a fluid-containing cavity of an engine includes a cover including a fluid-containing wall with a peripheral edge having a sealing surface adapted to oppose a corresponding sealing surface of the engine, and a plurality of mounting openings in the peripheral edge; a reaction pad adjacent each of the openings and disposed at the peripheral edge on an opposite surface of the sealing surface around a perimeter defining the cover; a brace disposed against the reaction pad around the perimeter defining the cover; and mechanical fasteners extending through the reaction pad and the brace for securing the cover to a mating edge of the engine cavity, the fasteners when engaged providing substantially equal compression forces on the reaction pad via the brace and supporting the cover sealing surface with a predetermined gap from the cavity mating edge for engagement with a compliant sealing material disposed between the surfaces.
