Abstract
Patente de Invenção:<B>"ABAFADOR DE RUìDO"<D>. Condicionado a tolerâncias de fabricação carregadores turbo ocasionam um ruído dependente de giro em máquinas de combustão, que em cada caso de carregador é nocivo, principalmente na faixa baixa de kHz. A tarefa aqui reside em uma redução de ruído desta faixa de ruído que surge neste durante a operação de veículo automotivo. O tubo de entrada de ar (1) posicionado entre o carregador turbo e a máquina de combustão, é de acordo com a presente invenção compartimento no interior com aparadores ou bastidores (5), onde as aberturas de aparadores (8) possuem pelo menos a largura livre da entrada (3) e da saída (4) e se alinham com estas. Os espaços intermediários (10), posicionando entre os aparadores (5) formam câmaras de resonância para ar que flui através destes, e que podem ser ajustados através da escolha de diferentes diâmetros de abertura (8) e/ou diferentes espaçamentos de aparadores, em uma larga faixa de abafamento de até mais de 20 dB (A) em uma faixa entre 1 kHz e 5 kHz. O abafador ou amortecedor de ruído por reflexão pode ser instalado em veículo automotivos.
