Abstract

Perfeccionamientos en válvulas moduladoras para sistemas de frenos de vehículos automóviles , compuestos por un generador de fluido a presión para alimentar fluido a presión por lo menos a un conjunto de rueda rotatorio, por una unidad de control que responde a la velocidad de rotación del conjunto de la rueda para alimentar 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, y por una válvula moduladora para regular la comunicación del fluido entre el generador de fluido a presión y el conjunto de la rueda en función a las señales de la unidad de control, comprendiendo la válvula moduladora una cámara de acumulación de volumen variable que se comunica por el generador de presión a través de una válvula de retención normalmente abierta y que se comunica además con el conjunto de la rueda, caracterizados porque comprende además medios para expandir el volumen de la cámara de acumulación mientras cierrala válvula de retención correspondiente en respuesta a la primera señal, y para contraer el volumen mientras cierra también la válvula de retención en respuesta a la segunda señal procedente de la unidad de control.
