Abstract

L'invention est relative à un mécanisme à fluide constitué par un stator 1, par un rotor 3, par un cylindre 2 dans lequel un piston 9 est monté coulissant et délimite une chambre de travail, le cylindre 2 étant attelé au stator I, l'autre élément 9 étant attelé au rotor 3, par des conduits d'aspiration dans la chambre et de refoulement, hors de cette chambre et par des obturateurs d'aspiration et de refoulement, l'un de ces obturateurs comprenant un clapet disposé dans un conduit interne ménagé dans le piston, cependant que le conduit interne comporte un tronçon 19 orthogonal à l'axe du piston et que l'obturateur correspondant au conduit interne comprend un clapet d'obturation du tronçon, et, la combinaison d'une rainure 16 ménagée dans le cylindre et de l'orifice par lequel le tronçon 19 débouche dans la face externe du piston. Un ressort 24, constitué par un anneau élastique 24, constitue le clapet d'obturation. Une application est la réalisation d'un mécanisme simple et robuste.
