Abstract

AMORTECEDOR. Trata-se de um absorvedor de choque por gás que tem um tubo de pressão que define uma câmara de trabalho. Um conjunto de pistão divide a câmara de trabalho em uma câmara de trabalho superior e uma câmara de trabalho inferior. Uma pluralidade de passagens de extensão se estende através do conjunto de pistão e são abertas e fechadas por um conjunto de válvula de extensão. Uma pluralidade de passagens de compressão se estende através do conjunto de pistão e são abertas e fechadas por um conjunto de válvula de compressão. Um conjunto de guia de haste esta localizado entre o tubo de pressão e a haste do pistão. O conjunto de guia de haste inclui uma câmara de óleo para vedar e lubrificar a haste do pistão. Um pistão axialmente móvel mantém, a pressão no interior da câmara de óleo equivalente à pressão na câmara de trabalho superior.
