Zusammenfassung:	PROBLEM TO BE SOLVED: To provide intershaft sealing systems for gas turbine engines and methods for assembling the same.SOLUTION: A seal assembly for use between an inner shaft (108) and an outer shaft (106) rotatable about a common axis (12) within a turbine engine (10) includes a pair of end rings (122, 124) and a plurality of seal elements (126) coupled between the pair of end rings. Each end ring includes flanges (134, 136) extending in an axial direction, and each seal element includes a pair of shoulders (170, 172) extending in opposing axial directions. The seal assembly also includes a pair of retaining rings (128, 130). 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.SELECTED DRAWING: Figure 3 【課題】ガスタービンエンジン用のシャフト間シールシステム及びこれを組み立てる方法を提供する。【解決手段】タービンエンジン（１０）内の共通軸線（１２）の周りに回転可能な内側シャフト（１０８）と外側シャフト（１０６）との間に用いるシール組立体は、一対の端部リング（１２２、１２４）と、端部リングの対の間に結合される複数のシール要素（１２６）とを含む。各端部リングは、軸方向に延びるフランジ（１３４、１３６）を含み、各シール要素は、対向する軸方向に延びる一対の肩部（１７０、１７２）を含む。シール組立体は、一対の保持リング（１２８、１３０）も含む。各保持リングは、肩部の対の１つの肩部と端部リングフランジの対の対応する１つの端部リングフランジとの間に配置される。【選択図】図３
