Abstract

Structure de tuyau renforcé flexible présentant des spires extérieures et un passage intérieur lisse. Le tuyau comprend un tube intérieur 24 en matière thermoplastique présentant un passage intérieur lisse 22, et un dispositif renforçateur 25 appliqué hélicoïdalement autour du tube 24 sans être noyé dans celui-ci et définissant la configuration hélicoïdale extérieure de la structure de tuyau, le tube intérieur présentant une épaisseur de paroi 30 suffisamment faible pour le rendre flexible. L'invention est applicable notamment à des appareils fonctionnant sous vide et plus spécialement à des aspirateurs de poussières.
