Abstract

A rotating assembly of a gas turbine engine includes a first rotating component 86; and a second rotating component 66 located radially outboard of the first rotating component 86, relative to an engine central longitudinal axis. A seal assembly 84 is configured to seal between the first rotating component 86 and the second rotating component 66. The seal assembly 84 includes a shuttle 92 located on a radial outer surface 94 of the second component 66 and freely axially movable along the radial outer surface 94 and a piston ring seal 88 retained in the shuttle 92 and engaged with the first rotating component 86. Axial motion of the first rotating component 86 relative to the second rotating component 66 urges movement of the shuttle 92 along the radial outer surface 94 of the second rotating component 66, while the position of the piston ring seal 88 remains stationary relative to the first rotating component 86.
