Abstract
Dispositif de blocage et de verrouillage d'aubes à pied en forme de marteau, dans une gorge 2a du rotor la. Les flancs latéraux 7, 8 du rotor sont entaillés à une certaine distance de la fenêtre d'introduction des pieds d'aubes 6, de manière à former un logement de révolution autour d'un axe radial 24 dans lequel peut tourner une pièce de butée de forme correspondante pourvue de deux entailles opposées qui lui permettent de coulisser le long desdits flancs latéraux 7, 8. La pièce de butée comporte un collet de diamètre réduit qui est engagé dans une portée pratiquée dans les plateaux jointifs de deux aubes adjacentes. L'invention s'applique notamment aux compresseurs axiaux.
