Abstract
LA INVENCION SE REFIERE A UN GRUPO DE UN SERVOMOTOR DE ASISTENCIA AL FRENADO Y DE UN CILINDRO PRINCIPAL DEL FRENO QUE COMPRENDE, EN UNA ENVOLTURA EXTERIOR (10), UN VOLUMEN DIVIDIDO DE MANERA ESTANCA EN UNA CAMARA DELANTERA (12) Y UNA CAMARA TRASERA (14) POR UNA MEMBRANA MOVIL (16), TENDIENDO AL MENOS UN PRIMER MEDIO ELASTICO (18) A DESPLAZAR LA MEMBRANA MOVIL HACIA LA CAMARA TRASERA, ESTANDO LA CAMARA DELANTERA CONECTADA A UNA FUENTE DE DEPRESION, SIENDO ESTABLECIDA UNA DIFERENCIA DE PRESION ENTRE LAS CAMARAS DELANTERA Y TRASERA MEDIANTE UN ELEMENTO DE VALVULA (20) SUSCEPTIBLE DE CONECTAR LA CAMARA TRASERA A LA ATMOSFERA EN EL MOMENTO DEL ACCIONAMIENTO DE UNA VARILLA DE MANDO (22) PARA DESPLAZAR LA MEMBRANA MOVIL HACIA LA CAMARA DELANTERA, UN CILINDRO PRINCIPAL DEL FRENO (30) FIJADO SOBRE LA PARTE DELANTERA DE LA ENVOLTURA Y QUE COMPRENDE UN ESCARIADO (40) EN EL QUE SE DESLIZA DE MANERA ESTANCA UN PULSADOR (42) SOLIDARIO DE LA MEMBRANA MOVIL Y QUE DELIMITA UN RECINTO (28) EN EL CILINDRO PRINCIPAL DEL FRENO, COMPRENDIENDO ESTE PULSADOR UN ESCARIADO (32) EN EL QUE SE DESLIZA DE MANERA ESTANCA UN EMBOLO DE REACCION (24) SOMETIDO A LA PRESION DEL RECINTO (18). SEGUN LA INVENCION UN SEGUNDO MEDIO ELASTICO PRETENSADO CARGA DICHO EMBOLO HACIA EL CILINDRO PRINCIPAL DEL FRENO.
