Abstract

La présente invention concerne un appareil de conversion d'énergie (10) qui comprend un logement (12) sous la forme d'un manchon et des agencements déflecteurs (14) qui font saillie depuis une surface interne (16) du logement (12). Le logement (12) présente une entrée (18) et une sortie (20) permettant à un fluide (22), tel que l'eau, de passer à travers le logement (12). Le logement (12) est supporté de manière rotative au moyen d'une paire de paliers (24) situés à des extrémités opposées de celui-ci de sorte que, lors de l'utilisation, sous l'influence du fluide (22) passant à travers le logement (12) et agissant contre les agencements déflecteurs (14), le logement (12) est amené à se mettre en rotation. Chaque agencement déflecteur (14) comprend une pale ou nervure allongée de forme hélicoïdale qui s'étend sensiblement entre l'entrée (18) et la sortie (20) du logement (12).
