Abstract

LA INVENCION SE REFIERE A UN AMPLIFICADOR DE FUERZA DE FRENADO NEUMATICO CON UNA CARCASA (10) DIVIDIDA EN UNA CAMARA (14) DE DEPRESION Y UNA CAMARA (12) DE TRABAJO, DONDE UNA DISPOSICION (20) DE DOBLE VALVULA ESTA APLICADA CON UNA PRIMERA VALVULA (24,26) ENTRE LA CAMARA (14) DE DEPRESION Y LA CAMARA (12) DE TRABAJO, Y UNA SEGUNDA VALVULA (14'', 26'') QUE ESTA DISPUESTA ENTRE LA ATMOSFERA (A) AMBIENTE Y LA CAMARA (12) DE TRABAJO SOBRE LA CARCASA (10). ESTA DISPOSICION (20) DE VALVULA, EN UNA POSICION INOPERATIVA, PERMITE UN NIVEL DE PRESION EN LA CAMARA (14) DE DEPRESION Y LA CAMARA (12) DE TRABAJO SEPARADA DE LA ATMOSFERA (A) Y, EN UNA POSICION DE TRABAJO, MANTIENE LA CAMARA (14) DE DEPRESION CERRADA Y PERMITE UNA CONEXION ENTRE LA ATMOSFERA (A) Y LA CAMARA (12) DE TRABAJO. EN OPERACION NORMAL LA PRIMERA VALVULA (14,26) Y LA SEGUNDA VALVULA (14''),26'') DEBEN SER ACTUADAS MEDIANTE UNA BARRA (34) DE ACTUACION COMPARTIDA Y EN OPERACION CONTROLADA EN UN DISPOSITIVO (40,46) DE ACTUACION ELECTROMAGNETICA INDEPENDIENTE DE LA BARRA (34) DE ACTUACION QUE PREVIENE UN ENLACE ENTRE LA CAMARA (14) DE DEPRESION Y LA CAMARA (12) DE TRABAJO SI LA BARRA DE ACTUACION ABRE LA PRIMERA VALVULA (24,26).
