Abstract

VALVULA DOSIFICADORA (40, 140) DE PRESIONES PRIMARIA Y SECUNDARIA COMPENSADAS, QUE PUEDE ROSCARSE EN UNA ABERTURA COMPLEMENTARIAMENTE CONFORMADA DE UN CILINDRO DIRECTOR (10). EL CONJUNTO DE VALVULA (40, 140) INCLUYE UN PISTON DE AREA DIFERENCIAL (50, 150) SOLICITADO POR UN RESORTE (70, 170) HACIA LA SALIDA (21, 121) QUE COMUNICA CON LOS FRENOS TRASEROS. EL CILINDRO DIRECTOR (10) INCLUYE UN PAR DE CONDUCTOS (16, 18) QUE COMUNICA PRESION DE FLUIDO Y PRESION DE FLUIDO SECUNDARIA DIRECTAMENTE AL PISTON DE AREA DIFERENCIAL (50, 150) DEL CONJUNTO DE VALVULA DOSIFICADORA (40, 140) PARA DESPLAZAR AL PISTON (50, 150) HACIA UNA POSICION EQUILIBRADA. EN EL CASO DE QUE EXISTA UN FALLO DE PRESION EN EL CIRCUITO DE FRENOS PRIMARIO, EL CONJUNTO DE VALVULA DOSIFICADORA (40, 140) ACCIONA AL PISTON DE AREA DIFERENCIAL (50, 150) PARA PERMITIR EL BYPASS DEL FLUJO DE FLUIDO RESPECTO AL PISTON (50, 150) PARA SU COMUNICACION DIRECTA CON LOS FRENOS TRASEROS DEL VEHICULO.
