Abstract (en)
[origin: WO2008110252A1] A pressurized air muffler (3) is proposed that is penetrated by an unobstructed air flow channel (7). A section of the length of the air flow channel (7) penetrates a sound-absorbing device (14) and joins on said sound-absorbing device with an air escape opening (17) to an expansion chamber (37), which is delimited by a multi-layer closing wall (35). The closing wall is penetrated by an air outlet channel (38) disposed in a laterally offset fashion relative to the air escape opening (17) and free of overlap, said closing wall comprising a sound-absorbing layer (46) that faces the expansion chamber (37) and is flanked on the rear thereof by a sound reflection layer (47).
