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 outwardly, and can include improved vent channel and vent passage means.

대표청구항 ▼

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 bearing vent means disposed in the face seal ring member, the vent means in flow communication with the relatively lower pressure region, and a first secondary sealing surface; (b) seal housing means including a second secondary sealing surface and a housing structure fixedly attached to the engine stationary member; (c) face seal ring support means including at least three pin and radially extending groove combinations, the pins positioned on one of the face seal ring member and the housing structure, and the grooves disposed on the other of the face seal ring member and the housing structure, the pin and groove combinations concentrically supporting the face seal ring member on the seal housing means for movement from a retracted position to establish a primary restrictor clearance between the primary flow restrictor means and a primary sealing surface on the engine rotating member, the face seal ring support means maintaining a circumferentially uniform radial clearance between the face seal ring and the seal housing means; and (d) secondary seal means biased into sealing engagement with the first and second secondary seal surfaces; and (e) wherein said primary flow restrictor means comprises a primary restrictor dam having a radially and circumferentially extending seal dam surface which is radially spaced apart from said gas bearing face surface, said primary restrictor dam being more effective in restricting fluid flow from the relatively higher pressure region to the relatively lower pressure region than a circumferentially extending labyrinth tooth.
