Abstract

Perfeccionamientos introducidos en las válvulas de dirección de distribuidor giratorio para servo-direcciones de vehículos automóviles, con un distribuidor giratorio, así como con un casquillo de válvula que rodea el distribuidor giratorio, por su perímetro exterior, con una distribución del medio de presión sobre un servo-motor a través de unos bordes de distribución de admisión y unos bordes de distribución de retorno dispuestos entre el distribuidor giratorio y el casquillo de válvula, así como un casquillo de cojinete entre el distribuidor giratorio y un tornillo sin-fin o un piñón respectivamente, situado en dirección longitudinal por detrás del distribuidor giratorio, estando destinado dicho casquillo de cojinete para la fijación del distribuidor giratorio, y del tornillo sin-fin o del piñón, respectivamente, caracterizados porque dentro de un segundo plano interior, entre el casquillo de cojinete y la pared interior de circunferencia del distribuidor giratorio, se encuentran dispuestos unos bordes de distribución adicionales para el mando del medio de presión.
