Abstract

AMORTECEDOR DE CHOQUE COM VÁLVULA PASSIVA DEPENDENTE DE FREQUÊNCIA. Um amortecedor de choque tem um tubo de pressão com um conjunto de êmbolo deslizantemente disposto no interior do tubo de pressão e preso a uma haste de êmbolo. O conjunto de êmbolo divide o tubo de pressão em uma câmara de trabalho superior e uma câmara de trabalho inferior. O conjunto de êmbolo inclui um conjunto de válvula dependente da frequência preso à haste de êmbolo, que define um alojamento preso à haste de êmbolo e um conjunto de válvula de bobina. O conjunto de válvula de bobina inclui uma válvula de bobina e os primeiro e segundo conjuntos de válvula de derivação que controlam o fluxo de fluido através da passagem de derivação que contorna o conjunto de êmbolo.
