Abstract: front page image
(EN) In a compressor rotor shaft (21), a ventilation flow path (22) is formed which guides into the compressor rotor shaft a compressed gas flowing between two moving blade rows (51) which are adjacent in the axial direction (Da). The ventilator flow path (22) comprises an introduction part (23), multiple branching parts (27) and a collection part (28). The introduction part (23) guides a compressed gas flowing between the two moving blade rows (51) into a compressor rotor shaft (21). The multiple branching parts (27) branch off from the introduction part (23) and are formed in mutually different positions in the axial direction (Da). The collection part (28) is connected to the multiple branching parts (27); compressed air that has passed through the branching parts (27) flows into the collection part and is made to flow from there to the outside.
(FR) Selon l'invention, un trajet d'écoulement de ventilation (22) qui guide dans sa partie interne un gaz comprimé circulant entre deux rangées de pales mobiles (51) adjacentes dans une direction axiale (Da), est formé au niveau d'un axe de rotor de compresseur (21). Le trajet d'écoulement de ventilation (22) possède une partie introduction (23), une pluralité de parties ramification (27) et une partie assemblage (28). La partie introduction (23) guide le gaz comprimé circulant entre les deux rangées de pales mobiles (51) à l'intérieur de l'axe de rotor de compresseur (21). La pluralité de parties ramification (27) se ramifient à partir de la partie introduction (23), et est formée en des positions différentes les unes des autre dans la direction axiale (Da). La partie assemblage (28) est connectée à chacune des parties ramification (27), et le gaz comprimé ayant traversé la pluralité de parties ramification (27) y circule, puis est déchargé dans une partie externe.
(JA) 圧縮機ロータ軸(21)には、軸方向(Da)で隣り合う二つの動翼列(51)の間を流れる圧縮気体を自身の内部に導くベンチレーション流路(22)が形成されている。ベンチレーション流路(22)は、導入部(23)と、複数の分岐部(27)と、集合部(28)とを有する。導入部(23)は、二つの動翼列(51)の間を流れる圧縮気体を圧縮機ロータ軸(21)内に導く。複数の分岐部(27)は、導入部(23)から分岐して、軸方向(Da)で互いに異なる位置に形成されている。集合部(28)は、複数の分岐部(27)のそれぞれと接続され、複数の分岐部(27)を通った圧縮気体が流れ込み、流れ込んだ圧縮気体を外部に流出させる。
