Abstract
ESTE ACCIONAMIENTO REGULADOR (1) TIENE UN EMBOLO PRINCIPAL (4) QUE SE ACTIVA POR PRESION DE ACEITE Y UNA CONTROL PREVIO QUE ESTA EN UNION EFECTIVA, MEDIANTE BARRAS (15), CON EL EMBOLO PRINCIPAL (4). EL CONTROL PREVIO TIENE UN REGULADOR (14) QUE REGULA LA PRESION DEL ACEITE EN EL EMBOLO PRINCIPAL (4) Y UNA GRUPO DE EMBOLOS DE CONTROL PREVIO (18) QUE SE ACTIVA HIDRAULICAMENTE. EL ACCIONAMIENTO REGULADOR (1) SE DISEÑA DE FORMA QUE TENGA UNA MAYOR DINAMICA EN FUNCIONAMIENTO. ELLO SE CONSIGUE PUDIENDO ACTIVAR EL GRUPO DE EMBOLOS DE CONTROL PREVIO (18) MEDIANTE UNA VALVULA ELECTROHIDRAULICA, QUE SE CONTROLA MEDIANTE UN REGULADOR ELECTRONICO (31).
