Abstract

Perfeccionamientos en sistemas de frenos de fluido a presión para vehículos del tipo que comprenden un circuito de frenos de servicio, un circuito de frenos de aparcamiento y por lo menos un accionador de los frenos que tiene un dispositivo de frenos de servicio conectado en el circuito de frenos de servicio y en comunicación con una fuente de fluido a presión cuando se efectúa el funcionamiento de los frenos de servicio, cuyo accionador de los frenos comprende un dispositivo de aparcamiento conectado en el circuito de los frenos de aparcamiento para mantener el accionador en estado de frenos echados cuando se hacen funcionar los frenos de aparcamiento, caracterizados porque se dispone en cada sistema de válvula de inmovilización que responde al nivel de fluido a presión que se comunica con el dispositivo de los frenos de servicio para evitar que se suelte el dispositivo de aparcamiento hasta que se comunica un nivel de presión predeterminado con el dispositivo de frenos de servicio.
