Abstract

SE PROPORCIONA UN SISTEMA DE AISLAMIENTO DE CAMARA A RESORTE, PARA AISLAR LA CAMARA A RESORTE DE UN ACTUADOR DE FRENO A RESORTE, DESDE SU MEDIO OPERATIVO. EL ACTUADOR DE FRENO (14) COMPRENDE UN ALOJAMIENTO (18) DE FRENO DE SERVICIO DIVIDIDO EN CAMARAS (26, 28) DE SERVICIO PRIMERA Y SEGUNDA MEDIANTE UN DIAFRAGMA O PISTON, Y UN ALOJAMIENTO (20) DE FRENO A RESORTE, SITUADO EN TANDEM CON, Y UNIDO A, EL ALOJAMIENTO DEL FRENO DE SERVICIO, TAMBIEN DIVIDIDO EN DOS CAMARAS (62, 63) A RESORTE PRIMERA Y SEGUNDA POR UN DIAFRAGMA (52) O PISTON. UN VASTAGO (56) ACTUADOR HUECO ESTA UNIDO AL DIAFRAGMA O PISTON EN EL ALOJAMIENTO DEL FRENO A RESORTE, Y SE EXTIENDE DESDE LA PRIMERA CAMARA A RESORTE, A TRAVES DE LAS ABERTURAS EN LOS ALOJAMIENTOS A RESORTE Y DEL FRENO DE SERVICIO, AL INTERIOR DE LA PRIMERA CAMARA DEL FRENO DE SERVICIO. EL VASTAGO ACTUADOR ESTA ABIERTO EN AMBOS EXTREMOS, PERMITIENDO QUE FLUYA EL AIRE DESDE LA PRIMERA CAMARA DE SERVICIO AL INTERIOR DE LA PRIMERA CAMARA A RESORTE, CUANDO AUMENTA EL VOLUMEN DE LA PRIMERA CAMARA A RESORTE.
