Abstract

"AMORTECEDOR DEPENDENTE DA FREQuêNCIA". Um absorvedor de impacto possui um tubo de pressao que define uma câmara de trabalho. Um pistão divide a câmara de trabalho em uma câmara de trabalho superior e em uma câmara de trabalho inferior. Um caminho de fluxo estende-se através do pistão para proporcionar comunicação do fluido entre as câmaras de trabalho superior e inferior. Um corpo de válvula está ligado com o tubo de pressão. O corpo de válvula define um caminho de fluxo entre a câmara de trabalho e uma câmara de fluido. A câmara de fluido está em comunicação com a câmara de trabalho superior ou com a câmara de trabalho inferior. A câmara de fluido pode ser definida dentro do tubo de pressão, entre o tubo de pressão e um tubo da câmara ou ela pode ser definida por uma montagem de mola atmosférica.
