Abstract

Mejoras introducidas en el objeto de la patente principal nº 474.387 por servo-amplificador de fuerza para sistema de frenos de vehículo, que incluye un cárter, una pared móvil que divide la pared del cárter en dos cámaras y que está adaptada para aplicar una fuerza al elemento de salida cuando las cámaras están sometidas a una diferencial de presión en respuesta a una fuerza aplicada a un elemento de entrada, un dispositivo fijo de transmisión de fuerza que se extiende a través de la pared móvil a partir de una pared del cárter hasta una pared del cárter situada en el lado opuesto de la pared móvil, y un dispositivo que asegura la estanqueidad de la pared móvil, directa o indirectamente respecto al dispositivo de transmisión de fuerza, caracterizadas porque el dispositivo de transmisión de fuerzas (16; 107) está dotado de un dispositivo de conducción (29, 30; 124, 124) que comunica con una de las cámaras.
