Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA ELIMINAR EL RUIDO DE CAVITACION PARA SERVOMECANISMO DE DIRECCION ASISTIDA. SE HACE CIRCULAR PERMANENTEMENTE UN FLUIDO EN EN CIRCUITO (26) CON DOS RAMAS PARALELAS (56, 57), PROVISTAS DE PASAJES CON ABERTURA VARIABLE, CONECTADAS ENTRE UNA FUENTE DE FLUIDO (27) Y UN DEPOSTIO (28). CADA RAMA COMPRENDE RESPECTIVAS TOMAS DE PRESION DE TRABAJO (37, 39), Y, CUANDO ESTA PRESION ALCANZA EN UNA DE LAS TOMAS UN UMBRAL CRITICO, MAS ALLA DEL CUAL PUEDEN PRODUCIRSE FENOMENOS DE CAVITACION, AL MENOS TODO EL FLUIDO QUE CIRCULA EN LA CORRESPONDIENTE RAMA SE HACE PASAR POR UNA RESTRICCION DE FLUJO (63) DISPUESTA ENTRE LA TOMA Y EL DEPOSITO EN SERIE CON UN PASAJE (62) CON APERTURA VARIABLE.
