Abstract

EL INVENTO SE REFIERE A UN CILINDRO PRINCIPAL TANDEM QUE CONSTA DE UN CUERPO (1) DOTADO DE UNA PERFORACION (2) POR LA QUE SE DESLIZAN, DE FORMA ESTANCA, UN PISTON DE ENTRADA (3) ENLAZADO AL DISPOSITIVO DE CONTROL DE LOS FRENOS DE UN VEHICULO Y UN PISTON INTERMEDIO (5), QUE DETERMINAN JUNTOS DOS CAMARAS DE PRESION (10,12) ENLAZADAS, RESPECTIVAMENTE, A UN CIRCUITO DE FRENADO, Y QUE CONSTA IGUALMENTE DE UN ORGANO DE CONTROL (17) DE LA RELACION ENTRE LAS PRESIONES QUE IMPERAN EN DICHAS CAMARAS (10,12). EL PISTON INTERMEDIO (5) ES UN PISTON ESCALONADO QUE CONSTA DE DOS PARTES QUE PRESENTAN UNOS DIAMETROS DIFERENTES EN RELACION A LAS CAMARAS Y QUE DETERMINA UNA CAMARA AUXILIAR (14) QUE PUEDE ENLAZARSE MEDIANTE EL ORGANO DE CONTROL (17), BIEN CON LA CAMARA DE PRESION EN RELACION A LA PARTE DE MENOR DIAMETRO (10), BIEN CON UN DEPOSITO DE BAJA PRESION (19). EL PISTON INTERMEDIO (5) CONSTA DE UNA PERFORACION INTERNA TUERTA ABIERTA EN LA PARTE DE MAYOR DIAMETRO, POR LA CUAL SE DESLIZA DE FORMA ESTANCA UN PISTON DE REACCION (22) FIJO EN RELACION AL CUERPO (1) Y QUE DETERMINA, EN EL INTERIOR DEL PISTON, LA CAMARA AUXILIAR (14). APLICACION EN EL FRENADO DE VEHICULOS AUTOMOVILES.
