Abstract

L'invention concerne un dispositif pour amplifier une force de direction d'une force d'entraînement à l'aide d'un moteur, et comprenant un organe de direction 4, un organe d'entraînement et un vérin. L'organe de direction 4 est muni de deux butées parallèles 6 coopérant avec des butées d'un élément complémentaire dans lequel une de fluide s'ouvre dans un espacement 27 ménagé entre les butées. Chaque conduit de sortie 30, 31 de fluide communique avec un espacement adjacent à chaque butée, du côté opposé au conduit d'amenée, les conduits de sortie communiquant à l'opposé l'un de l'autre avec un distributeur 20 qui commande le vérin. L'invention peut s'appliquer comme dispositif de servo-direction et pour la commande des outils de coupe.The invention relates to a device for amplifying a steering force of a driving force with the aid of a motor, and comprising a steering member 4, a driving member and a cylinder. The steering member 4 is provided with two parallel stops 6 cooperating with stops of a complementary element in which one of the fluid opens into a space 27 formed between the stops. Each outlet duct 30, 31 of fluid communicates with a spacing adjacent to each stop, on the side opposite to the supply duct, the outlet ducts communicating opposite one another with a distributor 20 which controls the cylinder. The invention can be applied as a servo-steering device and for controlling cutting tools.
