- 駆動ブレード外周列及び駆動ブレードの頂部に対して径方向においてクランプ係合されるバンド型周囲壁要素を備えたロータと、
少なくとも一つの圧縮媒体導入ノズル及びロータを囲む環状内面を有するステータと
を備えた軸流タービンモータにおいて、
前記壁要素が、前記ロータが所定の速度レベルに達するまで遠心力に抗し、かつ、その駆動ブレードとのクランプ係合を維持するが、前記所定の速度レベルを超えた速度レベルの時に、膨張して、その駆動ブレードとのクランプ係合を緩め、ハウジング環状内面と接触するよう配置され、それにより、ロータ(12)が危険な高速レベルに達することを防止し、
前記壁要素が前記駆動ブレードの頂部に相応した内部形状をもち、そして大きな内径部分と小さな内径部分とを有し、また、
前記大きな内径部分と同じ外径を有する少なくとも一つの外周リブを前記小さな内径部分に配置した
ことを特徴とする軸流タービンモータ。 - 前記壁要素が、一つ又は複数の脆弱部分を備え、
前記脆弱部分が、前記所定の速度レベルを超えた速度レベルの時に限界になることを目的とし、
それにより、壁要素を分裂させ、ロータの回転運動を妨げるようにする
ことを特徴とする請求項1に記載の軸流タービンモータ。
