| 摘要 |
The invention relates to a sound attenuator system of a compressed air treatment system of a motor vehicle, comprising a sound attenuator (24, 30) which has a housing (40) with an inlet opening (48) and at least one outlet opening (50), as well as a noise-reduction device (52) which reduces the flow noises of compressed air as it flows through same, and is arranged in the housing (40) between the inlet opening (48) and the at least one outlet opening (50). The sound attenuator system proposed here also comprises an additional noise-reduction device (58) which reduces the flow noises of compressed air as it flows through same, and is arranged upstream of the noise-reduction device (52). This additional noise-reduction device (58) comprises an inflow opening (62), at least one outflow opening (70) and at least one deflection element (64) for deflecting, in the direction of the at least one outflow opening (70), the compressed air flowing in through said inflow opening (62). |
