Abstract

Un servofreno de vacío para vehículos automóviles mejorado, que utiliza la diferencia entre una presión de vacío y la presión atmosférica y el cual comprende una caja de vacío en la que hay por lo menos un tabique móvil que la divide en una cámara de vacío y una cámara de trabajo y el cual acciona una varilla de empuje guiada en la dirección del eje del servofreno, caracterizado porque en el interior de la caja de vacío (2) hay un tubo (3) dispuesto en dirección al menos aproximadamente axial y conectado a las caras de los extremos de la caja de vacío (2), rodeando dicho tubo (3) a la varilla de empuje (18) y teniendo el tabique móvil (6) un desplazamiento estanco respecto a dicho tubo (3).
