Abstract

"ATENUADOR DE ONDA DE PRESSãO PARA UM TRILHO". A presente invenção refere-se a um atenuador (10) e um método de atenuação incluindo um oscilador mecânico para atenuação das ondas de pressão formadas em um trilho (12) possuindo um volume de fluido que inclui uma cavidade de fluido encerrada e rígida (96) possuindo um volume selecionado, o volume se comunicando com o fluido de atuação de trilho (18a, 18b) através de um orifício (92a, 92b) possuindo um volume selecionado para conter o fluido de atuação, o orifício possuindo uma abertura (93) em comunicação por fluido com o fluido de atuação selecionado de forma que quando uma onda de pressão impinge na abertura do orifício, o movimento do fluido de atuação no volume do orifício é conjunto para vibrar, a vibração agindo para excitar o fluido de atuação no orifício, devido ao cancelamento de fase entre o fluido de atuação no volume do orifício e o volume de fluido de atuação na cavidade encerrada, causando a absorção de energia da onda de pressão devido à dragagem por fricção no e em torno do orifício.
