Abstract

"SISTEMA DE TOMBAMENTO PARA O COLETOR DE ADMISSãO DE UM MOTOR DE COMBUSTãO INTERNA DOTADO DE UM ATUADOR FEITO DE UM MATERIAL COM MEMóRIA DE FORMATO". Um sistema de tombamento (13) para um coletor de admissão (3) de um motor de combustão interna (1) é dotado de um certo número de cilindros (2). O sistema de tombamento (13) compreendendo ao menos uma válvula borboleta (14) para variar a secção da passagem de ar através do duto de admissão (9), o qual conecta ao menos um cilindro (2) com o coletor de admissão (3). A válvula borboleta (14) apresenta uma borboleta (15) montada de tal forma a girar sob a ação de um dispositivo atuador (17), equipado com menos um primeiro elemento atuador (23), o qual é feito de um material com memória de formato e o qual gera um deslocamento através da modificação de sua geometria a seguir a aplicação de uma tensão externa de uma natureza física.
