Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a turbine portion variable purge flow seal member with improved sealing efficacy.SOLUTION: A turbomachine includes a compressor portion, and a turbine portion operatively connected to the compressor portion. The turbine portion includes a compressor discharge portion, a hot gas path and a first stage nozzle arranged at the hot gas path. A combustor assembly is fluidically connected to the compressor portion. A transition piece has an inlet portion fluidically connected to the combustor assembly and an outlet portion fluidically connected to the turbine portion. A seal member is operatively connected to one of the transition piece and the first stage nozzle of the turbine portion. The seal member extends from a first end to a second, cantilevered end through an intermediate portion including one or more openings that provide a purge fluid flow path from the compressor discharge portion toward the hot gas path.SELECTED DRAWING: Figure 1 【課題】シール有効性が改善されたタービン部分の可変パージ流シール部材を提供する。【解決手段】ターボ機械は、圧縮機部分と、該圧縮機部分に作動可能に接続されたタービン部分とを含む。タービン部分は、圧縮機吐出部分、高温ガス経路、及び該高温ガス経路に配置された第１段ノズルを含む。燃焼器組立体は、圧縮機部分に流体接続される。移行部品は、燃焼器組立体に流体接続された入口部分と、タービン部分に流体接続された出口部分と、を有する。シール部材は、移行部品及びタービン部分の第１段ノズルのうちの一方に対して作動可能に接続される。シール部材は、圧縮機吐出部分から高温ガス経路に向けたパージ流体流路を提供する１又はそれ以上の開口を含む中間部分を通って、第１の端部から第２の片持ち端部まで延びる。【選択図】図１
