Abstract

Perfeccionamientos maestros para sistemas de frenos hidráulicos de vehículos de motor, que tienen fresnos de disco para actuar sobre un conjunto de ruedas y fresnos de tambor para actuar sobre otro conjunto de ruedas, del tipo de cilindro maestro que comprende una primera cámara para conectarse a los frenos de tambor y que, en la práctica, se pone a presión por un primer pistón; una segunda cámara para conectarse a los fresnos de disco y que, en la práctica, se pone a presión por un segundo pistón; un dispositivo de válvula de retardo para regular el flujo desde la segunda cámara hasta los frenos de disco y un dispositivo de válvula de retención para permitir el flujo desde los frenos de disco hasta la segunda cámara; caracterizados porque el dispositivo de válvula de retardo se forma por un elemento de válvula que funciona conectado a uno de los pistones, de modo que el elemento de válvula se mueva para cortar la comunicación desde la segunda cámara hasta los frenos de disco durante el movimiento inicial del citado pistón en sentido contrario a la posición de liberación de los frenos, y un núcleo móvil accionado por la presión del fluido en la segunda cámara contra un muelle de control para volver a establecer la comunicación desde la segunda camara hasta los frenos de disco cuando la presión en la segunda cámara alcanza una magnitud predeterminada.
