Abstract

resumo patente de invenção: "válvula degressiva multiajustável". a presente invenção refere-se a absorvedor de choque que inclui um pistão disposto dentro de um tubo de pressão. um conjunto de válvulas é anexado ao pistão. o conjunto de válvulas define um primeiro fluxo de fluido através de uma passagem de fluido sempre aberta; um segundo fluxo de fluido é devido a uma deformação elástica de um disco de válvula do conjunto de pistão; e um terceiro fluxo de fluido é devido a um movimento de todo o disco de válvula em afastamento do pistão. em uma modalidade, o conjunto de válvulas é projetado para ser pré-montado em uma localização externa e/ou fora de linha.
