Abstract

Una válvula para freno de mano de uso en un sistema de freno hidráulico de vehículo en el que la presión hidráulica mantiene en la posición de liberado a un freno sometido a la acción de un muelle, caracterizada porque es establecida una conexión mecánica entre un husillo (16) de control de presión equilibrada para el control de la presión hidráulica en el freno sometido a la acción de un muelle (3) y una palanca de freno de mano (2) por un lado, habiendo un pistón de reacción (26) que se apoya contra el husillo de control del otro lado y habiendo dos superficies efectivas opuestas (27, 28) de las cuales la zona efectiva (28) correspondiente a la posición (29) que está en conexión permanente con una fuente de fluído (4) mientras que la zona efectiva (27) que comprende a la posición de freno activado hace frente a una cámara de presión (20) que está en conexión permanente con el freno sometido a la acción de un muelle (3).
