Abstract

UN MOTOR DE COMBUSTION INTERNA PARA VEHICULOS AUTOMOVILES EN EL QUE CADA CILINDRO TIENE ASOCIADO UN PAR DE VALVULAS DE ENTRADA Y/O ESCAPE (2, 3) CONTROLADAS POR RESPECTIVOS RETENES OSCILADORES (7, 8) QUE SON IDENTICOS Y TIENEN FULCROS RESPECTIVOS (14, 15) COLOCADOS EN CARAS OPUESTAS DE UN ARBOL DE LEVAS (4). LOS DOS OSCILADORES SON OPERADOS POR UNA LEVA (13) UNICA Y COMUN.AN INTERNAL COMBUSTION ENGINE FOR AUTOMOBILE VEHICLES IN WHICH EACH CYLINDER HAS ASSOCIATED A PAIR OF INLET AND / OR EXHAUST VALVES (2, 3) CONTROLLED BY RESPECTIVE OSCILLATING RETAINERS (7, 8) WHICH ARE IDENTICAL AND HAVE RESPECTIVE FUTURES (14 15) PLACED ON OPPOSITE SIDES OF A CAMSHAFT (4). THE TWO OSCILLATORS ARE OPERATED BY A SINGLE AND COMMON CAM (13).
