초록

A gas bearing face seal assembly for a gas turbine engine having improved sealing characteristics. The assembly can include support means which concentrically position a face seal member with respect to a seal radius, while permitting translation of the face seal with respect to a rotating sealing surface and radial growth of the seal member with respect to the housing. A clearance control ring means can be included to reduce and maintain radial clearance between the face seal member and a housing surface. The face seal member may be pressurized radially...
