Abstract
Perfeccionamientos introducidos en las válvulas de dirección con distribuidor giratorio para servodirecciones; de vehículos automóviles, junto con un distribuidor giratorio y un casquillo de válvula que rodea el distribuidor giratorio, con una distribución del medio de presión a un servo-motor a través de unos bordes de distribución de admisión, dispuestos entre el distribuidor giratorio y el casquillo de la válvula, y los bordes de distribución de retorno, situados entre el distribuidor giratorio y el casquillo de la válvula, conduciendo unos taladros de comunicación desde los bordes de distribución de retorno a un empalme de retorno, caracterizados porque los bordes de distribución están dispuestos entre sí de una forma tal que al estar la válvula en la posición neutral, existe una corriente sin estrangulamiento del medio de presión a través de los bordes de distribución y en dirección hacia el empalme de retorno, mientras que en la posición de una oblicuidad de la dirección, toda la corriente de éste medio de presión se encuentra guiada según cual sea el sentido de giro entre los bordes de distribución de admisión y los bordes de distribución de retorno, a través de, por lo menos, un lugar de estrangulamiento.
