摘要： A seal assembly is provided for a rotary machine wherein the rotary machine comprises a rotor and a casing. The rotor comprises a generally longitudinally-extending axis wherein the casing is generally coaxially aligned with the axis. The casing circumferentially surrounds and is radially spaced apart from the rotor wherein the casing comprises an inner circumferential channel generally coaxially aligned with the rotor. The seal assembly comprises a plurality of seal segments disposable in a circumferential array in the channel so as to be movable between radially inward and radially outward positions. In addition, the seal assembly comprises a plurality of displacement apparatuses comprising at least one fluid inlet and configured for urging apart the seal segments upon introduction of a fluid medium in the fluid inlet. Each of the seal segments comprises an end having at least one of the displacement apparatuses circumferentially disposed thereon.
