Embodiment Construction

[0051] figure 1 A schematic view of the carrier 12 for the sound-absorbing element in the first embodiment is shown. The bracket 12 is configured as an exhaust device 30 (not in figure 1 Components of a vertical blade shown in ). The support 12 has two bearing pins 18 , via which the vertical blades or the support 12 are rotatably mounted in the housing 31 of the exhaust device 30 . Furthermore, the support 12 has pins 20 , wherein a plurality of vertical blades or support 12 are pivoted via their pins 20 and via coupling rods which connect the individual pins 20 to one another. The support 12 configured as a frame has a step 22 on the inside, onto which a coating 14 is applied with a sound-absorbing material. The frame 12 preferably has a step 22 of this type on both sides, so that a coating of sound-absorbing material can be applied to the support 12 on both sides and can be connected to the support 12 . The region 23 enclosed by the step 22 and the frame-shaped carrier ...

Abstract

The invention relates to a sound-absorbent element for an air outlet, said air outlet comprising a housing with an air outlet opening and a connection to an air supply shaft, at least one sound-absorbent element being mounted in said housing and / or a housing of the air supply shaft, and said sound-absorbent element comprising a carrier that is connected to at least one layer of sound-absorbent material. Said at least one layer of sound-absorbent material comprises activated carbon, or at least one additional layer of activated carbon is applied to this layer of sound-absorbent material.

Description

technical field [0001] The invention relates to a sound-absorbing element for an exhaust device, wherein the exhaust device has a housing with an air outlet and a connection to the gas supply shaft, wherein at least one sound-absorbing element is supported on the In the housing and / or in the housing of the gas supply shaft, and the sound-absorbing element has a carrier, which is connected to at least one coating of sound-absorbing material. Background technique [0002] Numerous measures and devices for reducing noise in exhaust systems are known from the prior art. Thin, easily movable parts are usually mounted in these exhaust devices, which vibrate due to the exhaust air flow and thus generate disturbing noises. In motor vehicles in particular, such disturbing noises can also occur due to vibrations of vehicle components or when driving, for example, on uneven road surfaces, which likewise lead to vibrations or movements of thin parts of the exhaust system. On the other...
