Abstract

Appareil rotatif destiné à transférer l'énergie d'un fluide avec un bruit réduit. Il comprend un bloc-cylindres 10 comprenant plusieurs cylindres 11 dans lesquels des pistons 12 exécutent des mouvements alternatifs. Ce bloc-cylindre tourne par rapport à un plateau distributeur 20 qui présente des zones de transition comprenant des chambres de retenue de fluide au moyen desquelles la pression régnant dans les cylindres est modifiée progressivement de manière à se rapprocher de la pression régnant dans l'un des orifices 21 et 22 vers lequel le cylindre se déplace. Domaine d'application : pompes et moteurs à fluide.
