Abstract:
A metallic sealing ring comprising:a first annular beam section with a first annular sealing surface facing in a first axial direction to contact a first member for creating a first annular sealing dam therebetween;a second annular beam section with a second annular sealing surface facing in a second axial direction, which is opposite to said first axial direction, to contact a second member for creating a second annular sealing dam therebetween, said first and second annular sealing surfaces being substantially parallel to each other;an annular inner surface extending between said first and second sealing surfaces to form a central passageway; andan annular outer surface extending between said first and second sealing surfaces and spaced from said annular inner surface to form an annular column section of material extending between said first and second sealing surfaces and substantially perpendicular thereto,one of said annular inner and outer surfaces having an annular recess extending in a substantially radial direction to at least partly define an effective minimum width of said annular column section, said annular recess being configured to form a first diagonal brace section extending from said annular column section to said first beam section to control buckling of said first beam section and column section under axial compression of said sealing ring.
