Abstract

"MECANISMO DE AJUSTE PARA VáLVULAS". Um aparelho para ajustar as características de movimento de uma válvula de um motor, compreendendo um dispositivo de ajuste para variar o ângulo de abertura e fechamento de válvula, ou o levantamento de válvula incluindo um elemento guia móvel a partir da primeira posição para uma segunda posição, e possuindo uma trajetória adaptada para receber um membro guia de um dispositivo de atuação de válvula, o membro guia recebido na trajetória guia possuindo uma trajetória, quando o dispositivo de ajuste está na primeira posição, diferente da trajetória do membro guia quando o dispositivo de ajuste está na segunda posição.
