Abstract
Una válvula para freno de mano mejorada de un sistema de freno hidraúlico para vehículos en la que la presión hidraúlica mantiene en posición de liberado a un freno de resorte, caracterizada porque la válvula de freno de mano tiene un primer miembro obturador de válvula (13) que controla la presión que mantiene abierto al freno de resorte, manteniendo a este miembro obturador de válvula (13) en la posición de cerrado la fuerza de un primer muelle (12) que se apoya sobre dicho miembro obturador de válvula (13) y porque dicho muelle (12) descansa por el, otro lado en un dispositivo de carga de muelle (8) que está acoplado mecánicamente a una palanca de mano (7).
