Abstract

LA INVENCION SE REFIERE A UN DISPOSITIVO DE FRENADO AUTOMATICO PARA VEHICULO EQUIPADO DE AL MENOS UN CIRCUITO FLUIDICO QUE CONECTA UN CILINDRO PRINCIPAL DEL FRENO (10) A UN CIRCUITO UTILIZADOR QUE INCLUYE AL MENOS UN MOTOR DE FRENO (22) Y QUE COMPRENDE ADEMAS UNA BOMBA (30) SUSCEPTIBLE (30) SUSCEPTIBLE DE HACER CIRCULAR POR EL CIRCUITO UTILIZADOR MEDIANTE UNA VALVULA ANTIRRETROCESO (31) DEL FLUIDO A PRESION ELEVADA TOMADA EN UN DEPOSITO (28) A BAJA PRESION. ESTE DISPOSITIVO COMPRENDE, EN COMBINACION, UNA ELECTROVALVULA PROPORCIONAL CONECTADA AL CIRCUITO UTILIZADOR Y QUE COMPRENDE UNA SALIDA DE REGULACION (20). ESTA ELECTROVALVULA, EN REPOSO, CIERRA UNA COMUNICACION ENTRE EL DEPOSITO (28) Y LA ENTRADA DE ALIMENTACION DE LA BOMBA (30) Y, EN FUNCIONAMIENTO ABRE ESTA COMUNICACION Y REGULA LA PRESION DEL FLUIDO EN EL CIRCUITO UTILIZADOR. EL DISPOSITIVO COMPRENDE ADEMAS UN DISTRIBUIDOR DE COMPARACION (10), QUE CUANDO LA PRESION DEL FLUIDO EN EL CILINDRO PRINCIPAL DEL FRENO (10) ES SUPERIOR O IGUAL A LA DEL FLUIDO EN EL CIRCUITO UTILIZADOR, ABRE UNA COMUNICACION ENTRE EL CILINDRO PRINCIPAL DEL FRENO (10) Y EL CIRCUITO UTILIZADOR Y CIERRA UNA COMUNICACION ENTRE LA SALIDA DE REGULACION (20) DE LA ELECTROVALVULA Y EL DEPOSITO (28), MIENTRAS QUE HACE LO CONTRARIO EN EL CASO CONTRARIO.
