Abstract
Válvula de compuerta giratoria (1) para servodirecciones de vehículos automóviles, con un primer elemento de válvula que está unido solidariamente en rotación con un miembro de entrada (5) de la válvula, con un segundo elemento de válvula que está unido solidariamente en rotación con un miembro de salida (7) de la válvula, y con las características adicionales siguientes: el primer elemento de válvula está unido con el miembro de salida (7) de la válvula a través de un muelle de barra de torsión (12) y a través de un arrastre mecánico en forma de un acoplamiento de marcha muerta (6), los dos elementos de válvula están dispuestos coaxialmente móviles uno dentro de otro en una carcasa de válvula (4) y pueden ser hechos girar uno con relación a otro como máximo en la medida del recorrido de giro del acoplamiento de marcha muerta (6), el elemento de válvula radialmente exterior presenta ranuras longitudinales de control (8) interiores y el elemento de válvula radialmente interior tiene ranuraslongitudinales de control exteriores (10), las cuales cooperan una con otra para controlar un medio de presión hacia y desde dos recintos de trabajo de un servomotor y hacia una acometida de retorno (18) para un recipiente de medio de presión, caracterizada porque el retorno desde las ranuras longitudinales de control (8) del elemento de válvula radialmente interior que controlan el retorno hasta la acometida de retorno (18) se efectúa a través de un rodamiento (14, 21).
