Abstract
Patente de Invenção: <B>"AMORTECEDOR DE VIBRAçõES HIDRáULICO PARA AUTOMóVEIS"<D>. Para desenvolver um amortecedor de vibrações hidráulico para automóveis, com um cilindro (1), que contém líquido de amortecimento e uma haste de êmbolo (2) vedada, disposta de modo axialmente deslocável, que imerge no mesmo, em cuja extremidade inferior está fixado um êmbolo de amortecimento (3), que divide a câmara de cilindro em duas câmaras de trabalho (4,5), está dotado de passagens alteráveis, que são controladas por corpos de válvula de estrangulamento e apresenta, adicionalmente, uma passagem secundária para o estágio de pressão e tração, cuja seção transversal de passagem secundária é regulada por uma válvula magnética, que funciona em dois ou mais estágios, cuja bobina anular abre em maior ou menor grau uma corrediça de válvula (13), com o que duas ou mais aberturas de passagem secundária são liberadas sucessivamente, de tal modo que na manobra ou controle da passagem de corrente pelos canais de passagem secundária as infuências perturbadoras, provocadas pelas forças hidráulicas, em constante mudança, da corrente de meio de amortecimento, são reduzidas, pelo menos o primeiro canal de passagem secundária (27), ativado depois da posição de fechamento da corrediça de vávula (13), apresenta um estreitamento (33) distanciado da corrediça de válvula (13).
