Abstract

CON EL FIN DE AUMENTAR LA EFICACIA DE UN SERVOMOTOR DE ASISTENCIA (10) CUYA CAMARA POSTERIOR (18) CONTIENE UN ORGANO MOTOR AUXILIAR (28), QUE CONSTA DE UNA CAMARA DE PRESION (30) ENLAZADA A UNA FUENTE DE PRESION (34) A TRAVES DE UN DISPOSITIVO DE CONTROL (36), ESTE ULTIMO CONSTA DE UNA VALVULA (38) NORMALMENTE CERRADA, A TRAVES DE LA CUAL LA FUENTE (34) PUEDE COMUNICARSE CON LA CAMARA DE PRESION (30), Y UNOS ELEMENTOS DE ACCIONAMIENTO (40) DE DICHA VALVULA, LOS CUALES CONTROLAN AUTOMATICAMENTE LA APERTURA CUANDO LA PRESION EXISTENTE EN LA CAMARA POSTERIOR (18) EXCEDE DE UN VALOR DADO DE ACUERDO CON LA PRESION EXISTENTE EN LA CAMARA ANTERIOR (16) DEL SERVOMOTOR. DICHO EQUIPO PUEDE UTILIZARSE EN UN SISTEMA DE FRENADO DE VEHICULO AUTOMOVIL.
