Abstract

Un servofreno para vehículos automóviles que utiliza la diferencia de presión entre una presión de vacío y la presión atmosférica, comprendiendo una caja de vacío que tiene en su interior un tabique móvil, por lo menos, el cual divide a dicha caja de vacío en una cámara de vacío y una cámara de trabajo y acciona una varilla de empuje guiada en la dirección del eje del servofreno, caracterizado porque hay por lo menos un miembro transmisor de la fuerza (11, 12) que está conectado a los tabiques frontales de la caja de vacío (2), dispuesto más o menos paralelamente a la varilla de empuje (3), el cual atraviesa el tabique móvil (4, 4'') pudiendo deslizarse dicho tabique móvil (4, 4'') por él por medio de unos cierres estancos deslizables (13, 13'', 14, 14'').
