Abstract

UN SISTEMA TEMPORIZADOR (4) PARA CONTROLAR, MEDIANTE UN SOLO ARBOL DE LEVAS AEREO (10), TRES VALVULAS HOMOLOGAS, ADYACENTES (5, 6) DE UN CILINDRO DEL MOTOR DE COMBUSTION INTERNA; CADA VALVULA TIENE UN BOTADOR (12) COLOCADO ENTRE EL VASTAGO DE LA VALVULA (13) Y UNA LEVA DE CONTROL CORRESPONDIENTE (11) SOBRE EL ARBOL DE LEVAS. LOS BOTADORES ESTAN COLOCADOS CON SUS EJES LEVANTADOS LATERALMENTE Y ALTERNATIVAMENTE EN LADOS OPUESTOS, RESPECTO A LOS EJES DEL VASTAGO DE LA VALVULA CORRESPONDIENTES, PARA ASI DEFINIR UNA PRIMERA EXCENTRICIDAD (E1) ENTRE CADA VASTAGO DE LA VALVULA Y BOTADOR CORRESPONDIENTE EN UN PLANO PERPENDICULAR AL PLANO DE ARRIBA, EL VASTAGO DE LA VALVULA INTERMEDIO ESTA ALINEADO RESPECTO AL EJE DEL BOTADOR CORRESPONDIENTE MIENTRAS QUE LOS OTROS DOS VASTAGOS DE LA VALVULA ESTAN LEVANTADOS LATERALMENTE RESPECTO AL EJE DEL BOTADOR CORRESPONDIENTE Y SE DIRIGE HACIA EL VASTAGO DE LA VALVULA INTERMEDIA PARA SI DEFINIR, CON LOS BOTADORES CORRESPONDIENTES, UN SEGUNDA EXCENTRICIDAD (E2) PERPENDICULAR A LA PRIMERA. LOS BOTADORES SE PUEDEN COLOCAR ASI LADO A LADO Y ALINEAR CENTRALMENTE A LOS LARGO DEL EJE DEL ARBOL DE LEVAS.
