Abstract
A seal assembly including a low flow cloth ring seal having a cloth assemblage is provided for sealing a tubular cavity disposed between a tubular member and a mating body. The density of the cloth assemblage may be set according to a desired flow rate of gas through the cloth ring seal. In applications where more stiffness and strength is desired, the cloth ring seal may include a shim assemblage surrounded by the cloth assemblage.
Claims27
A seal assembly comprising:
- a cloth ring seal adapted to seal a tubular cavity between a first mating body and a second mating body, said cloth ring seal having an inner circumferential portion adapted to make sealing contact with the second mating body;
- wherein said cloth ring seal includes a cloth assemblage, the inner circumferential portion of said cloth ring seal adapted to make sealing contact with the second mating body including an outer peripheral portion of said cloth assemblage;
- wherein said cloth ring seal further includes a shim assemblage with an outer peripheral portion opposing an inner peripheral portion of said cloth assemblage, said shim assemblage including a plurality of planar shim strips welded together and an arcuate shim portion, said arcuate shim portion having a first end welded to a first planar shim strip and a second end coupled to a second planar shim strip, wherein said arcuate shim portion and said planar shims strips form a closed loop.
A seal assembly comprising:
- a cloth ring seal adapted to seal a tubular cavity between a first mating body and a second mating body, said cloth ring seal having an inner circumferential portion adapted to make sealing contact with the second mating body, said cloth ring seal further including a cloth assemblage;
- wherein said cloth ring seal further includes a shim assemblage with an outer peripheral portion opposing an inner peripheral portion of said cloth assemblage, said shim assemblage including a plurality of planar shim strips welded together and an arcuate shim portion, said arcuate shim portion having a first end welded to a first planar shim strip and a second end coupled to a second planar shim strip, wherein said arcuate shim portion and said planar shims strips form a closed loop.
A gas turbine engine, comprising:
- a cloth ring seal adapted to seal a tubular cavity between a first mating body and a second mating body, said cloth ring seal having an inner circumferential portion adapted to make sealing contact with the second mating body, said cloth ring seal further including a cloth assemblage;
- wherein said cloth ring seal further includes a shim assemblage with an outer peripheral portion opposing an inner peripheral portion of said cloth assemblage, said shim assemblage including a plurality of planar shim strips welded together and an arcuate shim portion, said arcuate shim portion having a first end welded to a first planar shim strip and a second end coupled to a second planar shim strip, wherein said arcuate shim portion and said planar shims strips form a closed loop.
