Abstract
A seal assembly and a rotary machine, such as a steam turbine, containing the seal assembly. A casing circumferentially surrounds a rotor and includes a circumferential channel open to the rotor. Seal segments are circumferentially arrayed in the channel and are movable between radially inward and outward positions. Circumferentially adjacent seal segments have circumferentially opposing surface grooves. A resilient and imperforate member is engaged in the grooves of circumferentially-adjacent seal segments circumferentially urging apart such segments and providing sealing between such segments.
