Claims (1)
金の形状記憶効果により半径方向内方に押圧される前記
シールリングを、これに対抗する付勢装置で支持し、こ
の付勢装置は定常運転時より比較的低い温度の運転時に
、前記シールリングを半径方向外方に拡げるように働く
ように設定したことを特徴とする軸流流体機械用シール
リング。The seal ring, which is pushed radially inward due to the shape memory effect of the shape memory alloy as the temperature changes at the mounting part of the seal ring, is supported by an opposing biasing device, and this biasing device is maintained at a steady state. A seal ring for an axial flow fluid machine, characterized in that the seal ring is set to expand radially outward during operation at a temperature relatively lower than during operation.
