Abstract

Prélèvement d'air de refroidissement pour refroidir un sous-ensemble tel que par exemple une turbine avec réglage automatique de la section d'écoulement d'air en fonction du régime du moteur. Selon l'invention, un élément d'obturation (40) est fixé pour coopérer avec un trou de prélèvement (33), le matériau qui constitue soit l'élément d'obturation soit la paroi où est pratiqué le trou, est d'un type dans lequel des courants de Foucault peuvent se créer, tandis qu'un aimant (35) est monté mobile en regard de cet agencement.
