Abstract

La présente invention a pour objet un mécanisme de commande rotatif, caractérisé en ce que, pour chaque piston 20, sa partie dans laquelle est prévue la crémaillère 19 porte un ou des éléments 24 en élastomère ou en résine synthétique à faible coefficient de frottement qui est ou sont placés de façon à être en permanence en contact avec la partie voisine de la paroi du cylindre 10, de sorte qu'il y a neutralisation des forces séparatrices engendrées par le rapprochement ou l'éloignement des pistons 20 et tendant à déplacer ladite partie de chacun des pistons vers la paroi du cylindre.
