Abstract
L'invention concerne un dispositif d'entraînement rotatif étanche à excentricité, notamment pour pompe volumétrique. Le dispositif comprend un arbre coudé (1), présentant un axe d'entrée (5) et un axe de sortie (10) parallèle et excentré de manière à effectuer un mouvement orbital circulaire, et une manchette (14) étanche et non tournante entourant l'arbre et comportant deux soufflets métalliques (19, 20) reliés par une bague de guidage (21) montée à coulissement longitudinal sur le tronçon intermédiaire incliné (17) de l'arbre. Utilisation pour transformer un mouvement rotatif en mouvement orbital circulaire avec une étanchéité absolue.
