Abstract

Un aparato de servodirección perfeccionado que incluye un árbol de entrada destinado a ser conectado a un volante de dirección, un árbol de salida dispuesto en relación coaxial con el árbol de entrada y destinado a ser conectado a una rueda de carretera dirigible, un rotor de vávula formado en uno de entre el árbol de entrada y el árbol de salida, y un manguito de vávula montado en el otro árbol y dispuesto de forma giratoria en relación circundante con el rotor de válvula, formando la combinación del rotor de válvula y el manguito de vávula una válvula de control que controla es suministro o la descarga de un fluido hidráulico a/o desde un cilindro de potencia de acuerdo con un desplazamiento angular relativo entre el árbol de entrada y el árbol de salida, caracterizado porque el rotor de válvula está formado en una sola pieza con un saliente dentro de la región del manguito de válvula, que está formado con una abertura a través de la cual se proyecta externamente el extremo libre del saliente, estando dispuesto el saliente en la abertura de manera que deje un espacio de holgura dado entre ellos, según se ve en el sentido de rotación del manguito de válvula, estando provisto integralmente el manguito de válvula de otro saliente, estando mantenidos los dos salientes en posiciones dadas por la elasticidad de un muelle que está dispuesto en relación circundante con el manguito de válvula.
