Abstract

LA INVENCION SE REFIERE A UN SERVOMOTOR NEUMATICO DE FRENADO QUE UTILIZA DOS FUENTES DE PRESION DE AIRE Y QUE COMPRENDE UNA ENVOLTURA RIGIDA (3) SEPARADA POR UN TABIQUE MOVIL ESTANCO (4) EN AL MENOS DOS CAMARAS (3A, 3B), SIENDO EL TABIQUE MOVIL SUSCEPTIBLE DE SER SOLICITADO POR UNA DIFERENCIA, PROVOCADA POR UN ACCIONAMIENTO DE LA CHAPALETA, ENTRE LAS PRESIONES PROPORCIONADAS A LAS CAMARAS PARA ARRASTRAR UN PISTON NEUMATICO (5) QUE LLEVA UNA CHAPALETA DE CONTROL (7), ESTANDO EL INTERIOR (50) DE ESTE PISTON SEPARADO DE LA SEGUNDA FUENTE POR UN FILTRO DE DEPURACION (14). EL SERVOMOTOR DE LA INVENCION LLEVA MEDIOS DE OBTURACION (16, 51) CON ABERTURA CONTROLADA, INSTALADOS ENTRE LA SEGUNDA FUENTE DE PRESION (A) Y EL INTERIOR (50) DEL PISTON Y QUE CONTROLAN UNA VIA DE ADMISION DE AIRE (15) QUE CONECTA LA SEGUNDA CAMARA (3B) CON LA SEGUNDA FUENTE DE PRESION (A) EVITANDO EL PASO DEL FILTRO (14) Y DE LA CHAPALETA (7), Y MEDIOS ELASTICOS (17), SENSIBLES A UNA DIFERENCIA DE PRESION ENTRE EL INTERIOR DEL PISTON Y LA SEGUNDA FUENTE DE PRESION, PARA PERMITIR LA ABERTURA DE LOS MEDIOS DE OBTURACION CUANDO ESTA DIFERENCIA SOBREPASA UN UMBRAL DETERMINADO.
