Abstract

MECANISMO PARA ACCIONAR AL MENOS UNA VALVULA DE UN MOTOR DE COMBUSTION INTERNA, QUE INCLUYE UN ARBOL DE LEVAS (2) GIRATORIO EN SINCRONIA CON EL GIRO DEL MOTOR Y CON UN PAR DE LEVAS (3,5), LENTA Y RAPIDA, DE DIFERENTES PERFILES, UN EJE OSCILANTE (6) Y UN PRIMER Y UN SEGUNDO BRAZOS OSCILANTES (7,8) MONTADOS GIRATORIAMENTE SOBRE EL EJE Y ACCIONABLES DE FORMA SELECTIVA POR LAS LEVAS LENTA Y RAPIDA PARA OPERAR LA VALVULA SEGUN LOS PERFILES DE LAS LEVAS. UN ACOPLADOR SELECTIVO (21) ESTA SITUADO OPERATIVAMENTE ENTRE EL PRIMER Y EL SEGUNDO BRAZO OSCILANTE PARA CONECTARLOS EN EL FUNCIONAMIENTO DE ALTA VELOCIDAD DEL MOTOR, Y PARA DESCONECTARLOS CUANDO ESTE FUNCIONA A BAJA VELOCIDAD.MECHANISM TO ACTUATE AT LEAST ONE VALVE OF AN INTERNAL COMBUSTION ENGINE, WHICH INCLUDES A CAMSHAFT (2) ROTATING IN SYNCHRONY WITH THE TURN OF THE ENGINE AND WITH A PAIR OF CAMS (3,5), SLOW AND FAST, OF DIFFERENT PROFILES , AN OSCILLATING AXLE (6) AND A FIRST AND A SECOND OSCILLATING ARMS (7,8) ROTALLY MOUNTED ON THE AXLE AND SELECTIVELY OPERABLE BY THE SLOW AND FAST CAMS TO OPERATE THE VALVE ACCORDING TO THE PROFILES OF THE CAMS. A SELECTIVE COUPLER (21) IS OPERATIVELY LOCATED BETWEEN THE FIRST AND SECOND OSCILLATING ARMS TO CONNECT THEM TO THE HIGH-SPEED OPERATION OF THE MOTOR, AND TO DISCONNECT THEM WHEN THEY OPERATE AT LOW SPEED.
