Abstract

LA PRESENTE ESPECIFICACION DIVULGA UNA SERVO-UNIDAD PARA USO EN UN SISTEMA DE FRENOS DE VEHICULO, COMPUESTA DICHA SERVO-UNIDAD POR UN ALOJAMIENTO (1) DENTRO DEL CUAL UN DIAFRAGMA FLEXIBLE (7) SEPARA UNA CAMARA DE PRESION AL VACIO (3) DE UNA CAMARA A PRESION ATMOSFERICA (5). UN MONTAJE DE VARILLA ACCIONADORA (11) SE EXTIENDE DESDE EL ALOJAMIENTO (1) E INCLUYE UN CONJUNTO DE VALVULA (17) CON UN EMBOLO DE CONTROL DE VALVULA (23) QUE TIENE UNA CUÑA EXTENDIDA LATERALMENTE (21), QUE PUEDE ACOPLARSE CON UN TOPE FIJO DEL ALOJAMIENTO (1) PARA LIMITAR EL MOVIMIENTO DEL PISTON DE CONTROL DE VALVULA (23) Y CAUSAR UN EQUILIBRIO EN EL CONJUNTO DE VALVULA (17) ENTRE LA PRESION DE VACIO Y ATMOSFERICA. SE PROVEE TAMBIEN UNA VALVULA DE SOLENOIDE (25), QUE PUEDE CONTROLARSE PARA CONECTAR UN MIEMBRO DE PASO FLEXIBLE (29) QUE SE EXTIENDE ALREDEDOR DEL MONTAJE DE VARILLA ACCIONADORA (11), A TRAVES DE LA CAMARA DE PRESION AL VACIO (3), ENTRE EL ALOJAMIENTO (1) Y EL DIAFRAGMA (7), EN LA REGION DEL CONJUNTO DE VALVULA (17), CON DICHA CAMARA DE PRESION AL VACIO (5) O PARA CONECTAR AMBOS MIEMBROS DE PASO FLEXIBLE (29) Y UNA DERIVACION (31; 37, 39; 35; 41, 45; 47) QUE CONDUCE DESDE LA VALVULA DE SOLENOIDE A DICHA CAMARA A PRESION ATMOSFERICA (5), A LA ATMOSFERA. LA DERIVACION INCORPORA UNA VALVULA UNIDIRECCIONAL (39; 49).
