Abstract
Hélice à pas variable automatique La présente description concerne un dispositif comportant une hélice (11) à pas variable, dans lequel un écoulement (116) externe d’un fluide engendre, par effet Venturi, une dépression dans un premier compartiment (151) d’une chambre (15) comportant un ou plusieurs premiers orifices (131) non parallèles à un axe (113) de rotation de l’hélice (11), une variation de cette dépression provoquant un déplacement d’une cloison mobile (17) actionnant un mécanisme de modification du pas de l’hélice (11). Figure pour l'abrégé : Fig. 2
