Abstract

a presente invenção refere-se a um silencioso do escapa-mento no qual uma pluralidade de câmaras de expansão, incluindo uma câmara de expansão possuindo uma extremidade a jusante de uma abertura de tubo de entrada nela estão formados dentro de um invólucro de modo que o gás de escape flui em sequência através do mesmo, e um tubo de saída possuindo uma extremidade a montante da mesma abertura em, entre a pluralidade de câmaras de expansão, a última câmara de expansão na sequência de fluxo do gás de escape e que tem uma extremidade a jusante da mesma abertura para o ar é formado de modo a dobrar no interior do invólucro de modo a ter uma parte curva substancialmente em forma de u em pelo menos um local, em que uma câmara de absorção de som (23) formada no interior do invólucro (12) de modo a ser adjacente à última câmara de expansão (17) na sequência de fluxo dos gases de escape é preenchida com um material absorvente de som (24), e uma pluralidade de furos perfurados (25) são fornecidos em uma parte, que está virada para a câmara de absorção de som (23) do tubo de saída (19). isto permite que o silenciador de escape seja formado de uma forma compacta ao mesmo tempo melhorando a durabilidade e o desempenho de absorção de som.The present invention relates to an exhaust muffler in which a plurality of expansion chambers, including an expansion chamber having an end downstream of an inlet pipe opening therein are formed within a housing such that exhaust gas flows sequentially therethrough, and an outlet tube having an upstream end of the same opening in, between the plurality of expansion chambers, the last expansion chamber in the exhaust gas flow sequence and having a downstream end of the same air opening is formed to fold within the housing to have a substantially u-shaped curved portion in at least one location, wherein a sound-absorbing chamber (23) formed in the The interior of the housing (12) so as to be adjacent to the last expansion chamber (17) in the exhaust flow sequence is filled with a sound absorbing material (24), and a plurality of holes The perforated holes (25) are provided in one portion which faces the sound-absorbing chamber (23) of the outlet tube (19). This allows the muffler to be compactly formed while improving durability and sound absorbing performance.
