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...
A gas bearing face seal assembly for use in a gas turbine engine to restrict fluid flow from a relatively higher pressure region to a relatively lower pressure region at a juncture of an engine stationary member and an engine rotating member mounted for rotation about an axis, the assembly comprising: (a) a face seal ring member including a gas bearing face surface, a primary flow restrictor means, passage means disposed in the face seal ring member for providing fluid communication between the higher pressure region and the gas bearing face surface, gas...
