Abstract

UN SISTEMA HIDRAULICO, MODULAR Y AUTONOMO PARA EL REGLAJE DE LAS VALVULAS DE UN MOTOR DE COMBUSTION INTRNA COMPRENDE UNA TAPA DE VALVULAS ESPECIALMENTE ADAPTADA QUE INCLUYE, SOLIDARIAMENTE, UNA LEVANTAVALVULAS HIDRAULICO, UNA VALVULA DE SOLENOIDE Y PASOS DE FLUIDO QUE CONECTEN FLUIDICAMENTE EL LEVANTAVALVULAS Y LA VALVULA DE SOLENOIDE. EN UNA MODALIDAD, PISTONES EMPUJADORES DE LEVAS Y PISTONES ACCIONADORES DE VALVULAS, SEPARADOS, FORMAN RESPECTIVAS CAMARAS CONECTADAS POR FLUIDO EN UNA CAJA SOLIDARIA CON LA TAPA DE VALVULAS, ESTANDO TAMBIEN DICHAS CAMARAS EN COMUNICACION FLUIDICA CON LA VALVULA DE SOLENOIDE POR MEDIO DE UN PASO DE CONTROL. EL MOVIMIENTO DE SEGUIMIENTO DE LA LEVA DEL PISTON EMPUJADOR DE LEVA PUEDE SER TRANSFERIDO HIDRAULICAMENTE AL PISTON ACCIONADOR DE LA VALVULA CUANDO LA VALVULA DE SOLENOIDE ES ACTIVADA, PARA ABRIR UNA DE LAS VALVULAS DEL MOTOR O PARA ABRIR SIMULTANEAMENTE UN NUMERO DE VALVULAS.
