Abstract

La présente invention a pour objet un mécanisme de commande en rotation à pistons et crémaillères actionné de façon pneumatique, caractérisé par le fait que la charge qui est imposée à chacun des deux pistons est absorbée par deux organes de guidage parallèles 21, dont l'un est fixé par une extrémité à l'un 14 desdits pistons et dont l'autre est fixé par une extrémité à l'un 14 desdits pistons et dont l'autre est fixé par une extrémité à l'autre piston 15, chaque piston étant raccordé à une crémaillère 16, les déplacements longitudinaux de ces pistons provoquant chaque fois une rotation, dans l'un des deux sens opposés, d'un arbre 20 autour de son axe de rotation qui est perpendiculaire à l'axe longitudinal du cylindre, celle des extrémités de chaque organe de guidage 21 qui n'est pas fixée au piston correspondant pénétrant dans un palier cylindrique 18 de forme allongée, porté par l'autre piston, aucun de ces organes de guidage n'étant en aucune façon maintenu par les extrémités du cylindre.The present invention relates to a pneumatically actuated piston-and-rack rotation control mechanism, characterized in that the load which is imposed on each of the two pistons is absorbed by two parallel guide members 21, one of which is fixed by one end to one 14 of said pistons and the other of which is fixed by one end to one 14 of said pistons and the other of which is fixed by one end to the other piston 15, each piston being connected to a rack 16, the longitudinal displacements of these pistons causing each time a rotation, in one of the two opposite directions, of a shaft 20 around its axis of rotation which is perpendicular to the longitudinal axis of the cylinder, that of the ends of each guide member 21 which is not fixed to the corresponding piston penetrating into a cylindrical bearing 18 of elongated shape, carried by the other piston, none of these guide members being in any way held by the ends of the cy lint.
