摘要： An apparatus and method are provided for sealing an outer surface 170 of a shaft 175 to an inner surface 165 of a hub 160. The seal includes a magnet 155, with top and bottom pole pieces 260, 265, and a ferrofluid 270 magnetically held in a gap 275 between the pole pieces 260, 265, and the hub 160 or the shaft 175. The top pole piece 260 has a cross-section that is L-shaped, with a horizontal portion 260a parallel to the magnet 155 and a shorter vertical portion 260b facing the shaft 175. In one version, the vertical portion 260b or the portion of the shaft 175 facing it is contoured to provide a flux gradient that axially concentrates the ferrofluid 270 in the gap 275. In another aspect, a catcher 335 is provided to reduce loss of ferrofluid 270 when the ferrofluidic seal 185 used to form an outside seal. In yet another aspect, a stationary ferrofluidic seal 345 is provided for sealing a stationary shaft 350 to a rotating hub 355.

摘要： A brush seal is provided between static components of a turbine. The turbine flowpath has an inlet spaced from another the inner web of the first stage nozzle. A brush seal is disposed between the two static components to minimize leakage flow to the packing casing region. The bristles of the brush seal are preloaded to fill any gap between the static components caused by distortion or out-of-roundness of the opposed surfaces being sealed. A side plate may contact the opposed sealing surface, increasing the pressure capability of the brush seal and minimizing overall seal leakage by providing the minimum possible flow area restricted solely by the bristles.
