Zusammenfassung:	A seal assembly for use between an inner shaft and an outer shaft rotatable about a common axis within a turbine engine includes a pair of end rings and a plurality of seal elements coupled between the pair of end rings. Each end ring includes a flange extending in an axial direction, and each seal element includes a pair of shoulders extending in opposing axial directions. The seal assembly also includes a pair of retaining rings. Each retaining ring is positioned between one shoulder of the pair of shoulders and a corresponding one end ring flange of the pair of end ring flanges.
