Abstract

"ABSORVEDOR DE CHOQUE". Um absorvedor de choque inclui um conjunto de válvula de recuo o qual realiza a função de disco de flexão normalmente requerida para se permitir a passagem de fluido de um lado de um conjunto de pistão para o lado oposto durante o curso do absorvedor de choque. O conjunto de válvula de recuo também incorpora uma função de sangria, a qual aumenta o escoamento de fluido através do pistão, quando a pressão de fluido sendo exercida sobre o conjunto de válvula de recuo exceder a um nível especificado. O recurso de sangria utiliza uma mola em espiral para proteger o absorvedor de choque bem como o sistema de suspensão no qual o absorvedor de choque é montado.
