Abstract
Perfeccionamientos en sistemas de freno para vehículos, que tienen por lo menos un conjunto de ruedas rotatorio, del tipo que comprenden un generador de fluido a presión para alimentar fluido a presión al conjunto de la rueda al frenar, una válvula moduladora para regular la comunicación de fluido entre el generador de fluido a presión y el conjunto de la rueda, un elemento de acumulación de fluido a presión abastecido con fluido a presión por una fuente de fluido a presión y conectado además a la válvula moduladora y una unidad de control que responde a la velocidad de rotación del conjunto de la rueda para suministrar a la válvula moduladora una primera señal en presencia de un estado de derrape y una segunda señal en presencia de un estado de patinamiento del conjunto de la rueda, caracterizados porque la válvula moduladora se diseña para responder a la aparición de la primera señal de la unidad de control cerrando la comunicación entre el generador de fluido a presión y el conjunto de la rueda y abriendo simultáneamente la comunicación entre este último y el depósito de descarga y a la extinción de descarga y el conjunto de la rueda y abriendo la comunicación entre este último y el elemento de acumulación de fluido a presión antes de restablecer la comunicación inicial del mismo con el generador de fluido a presión, y para responder a la aparición de la segunda señal de la unidad de control cerrando la comunicación entre el generador de fluido a presión y el conjunto de la rueda y abriendo simultáneamente la comunicación entre este último y el elemento de acumulación de fluido a presión y a la extinción de la segunda señal restableciendo la comunicación inicial del conjunto de la rueda con el generador de fluido a presión.
