Abstract

Mejoras introducidas en un vacuorreforzador constituido por un cárter, un pistón de accionamiento que incluye un diafragma elástico y que divide el interior del cárter en dos cámaras, un vástago de entrada para accionar el mecanismo de entrada con el objeto de generar una presión diferencial entre dichas dos cámaras y un vástago de salida que recibe la fuerza de presión diferencial a partir del pistón de accionamiento, estando dichas mejoras caracterizadas porque consisten en que la extremidad interna del vástago de salida está soportada de manera deslizante en un elemento del lado pistón de accionamiento con acoplamiento entre elemento macho y elemento hembra entre ellos.
