摘要：
The claimed invention illustrates a solution that will make it possible to lead exhaust gas from a combustion engine (10) through a noise insulating cover (11) without reducing the noise insulating effect of the cover (11). This is possible by leading the exhaust gas through an expansion chamber (15) made of a material that insulates the cover (11) from the high temperature exhaust gas. The expansion chamber (15) is shaped so that the exhaust gas is lead through a curved channel in order to prevent the noise from spreading outside the cover (11).
摘要（中）：
要求保护的发明示出了一种解决方案，其可以使来自内燃发动机（10）的废气通过噪声绝缘盖（11）而不降低盖（11）的隔音效果。 这可以通过使排气通过由盖（11）与高温废气绝缘的材料制成的膨胀室（15）引导。 膨胀室（15）成形为使得排气通过弯曲的通道引导，以防止噪声扩散到盖（11）的外部。
