Abstract

LA INVENCION DESCRIBE UN PISTON PARA UN MOTOR DE COMBUSTION INTERNA CON UNA CABEZA DEL PISTON QUE TIENE AL MENOS UNA RANURA DE ARO (2) Y UNA BARRA DE CONEXION CON UNA PERFORACION CON PASADOR DE PISTON (3) Y UN TIEMPO DE COMPRESION MENOR DEL 40% DEL DIAMETRO DEL PISTON. PARA COMPENSAR EL EFECTO DE LA EXPANSION DE CALOR DE LA MEJOR MANERA POSIBLE Y PERMITIR EL FUNCIONAMIENTO SUAVE DEL PISTON EN UN CILINDRO (8), LA INVENCION HA TENIDO EN CUENTA QUE EL AREA DIAMETRICA MAYOR (5) DE LA BARRA DE CONEXION (4) ESTE COLOCADA EN LA REGION DE UN PLANO QUE VA PERPENDICULAR AL PLANO (7) QUE GENERA EL EJE Y QUE RODEA AL EJE DEL PASADOR DE PISTON (6).
