Abstract

EN ORDEN A ACCIONAR LA PRESION OPERADORA DE FLUIDO A LOS MIEMBROS DE FRENO DE LAS RUEDAS, HA SIDO LLEVADO A CABO UNA OPERACION DE ANTI - BLOQUEO, UNOS MEDIOS DE BOMBEO (8, 10, 12) ESTAN PROVISTOS TAL QUE SON DIRIGIDOS POR LA PRESION SUBATMOSFERICA (VACIO) EXISTENTE EN LA TUBERIA DE ENTRADA (D) DE LA MAQUINA. LA APLICACION DE LA PRESION DE FRENADO ES CONTROLADA POR UNA VALVULA (3) QUE RECIBE UNA SEÑAL DE ORDEN DE APERTURA CONSISTENTE EN EL TREN DE IMPULSOS DE UN DISPOSITIVO DE CONTROL (18). AL MENOS UN SENSOR DE VACIO (19) ESTA PROVISTO TAL QUE GENERA UNA SEÑAL DE CONTROL INDICATIVA DEL NIVEL DE VACIO PRESENTE EN LA TUBERIA DE ENTRADA (D). EL DISPOSITIVO DE CONTROL (18) CAUSA LA APERTURA DE LA VALVULA (3) CON UNA SEÑAL DE ORDEN CUYO VALOR INDIVIDUAL ES INVERSAMENTE PROPORCIONAL AL NIVEL DE LA SEÑAL DE CONTROL GENERADA POR EL SENSOR DE VACIO (19).
