Abstract

CONJUNTO DE ELEMENTOS PARA LA PUESTA EN FASE VARIABLE DE LAS VALVULAS DE UN MOTOR, EN ESPECIAL DE UN MOTOR DE COMBUSTION INTERNA. EL CONJUNTO DE ELEMENTOS EN CUESTION CONSTA ESENCIALMENTE, POR CADA VALVULA O GRUPO DE VALVULAS (9) DE ASPIRACION Y/O ESCAPE, DE UN ORGANO MOVIL DE REGULACION A DEDO (1) INTERPUESTO ENTRE LA LEVA DE MANDO (3) DE LA VALVULA CORRESPONDIENTE (9) Y UNA SUPERFICIE PLAN Y AMPLIA (4) ACOPLADA AL EXTREMO DE MANDO DE LA VALVULA. LOS ORGANOS DE REGULACION (1) SON MOVILES EN SENTIDO LONGITUDINAL ENTRE LAS RESPECTIVAS LEVA (3) Y SUPERFICIE PLANA (4) CON LAS QUE ESTOS ENTRAN EN CONTACTO A LO LARGO DE LINEAS PARALELAS AL ARBOL DE LEVAS (7), MIENTRAS SUS CENTROS DE ROTACION (2) SE DESPLAZAN A LO LARGO DE TRAYECTORIAS ARQUEADAS O RECTILINEAS PREVISTAS EN UN LADO DE LAS LEVAS (3) Y DE LAS SUPERFICIES PLANAS.
