Abstract

Conjunto de cilindro principal amplificado para sistema de freno de vehículo, que incluye un conjunto de cilindro hidráulico principal y un conjunto de servoamplificador, estando constituido el conjunto de cilindro principal por un cárter de cilindro principal provisto de un agujero en el cual puede deslizarse un pistón de cilindro principal, y estando constituido el conjunto de servoamplificador por un cárter de servoamplificador y un elemento de salida para aplicar una fuerza al pistón del cilindro principal, estando el cárter de cilindro principal conectado al cárter de servoamplificador, e incluyendo el conjunto de cilindro principal una válvula de recuperación sensible a la posición axial del pistón de cilindro principal en dicho agujero, una conexión entre el elemento de salida del conjunto de servoamplificador y el pistón de cilindro principal, y un dispositivo elástico que empuja tanto el elemento de salida como el pistón de cilindro principal hacia atrás, estando dicho conjunto decilindro principal caracterizado porque la posición de retroceso del pistón y del elemento de salida está determinada por un tope (31) soportado por el cárter de cilindro principal (21).
