Abstract (en)
[origin: EP1857682A1] Rotating piston machine (10) comprises a reaction sound absorber (50) which is divided by separating walls (55) into chamber parts (51b-e) and an inner tube (52b, 52e) passing through each chamber part to feed gas through the sound damping chamber. Slots (54) are arranged on the inner tube. Preferred Features: The slots are separated in the peripheral direction by bars. The ratio of the bar surface to the slot surface is less than 30%, preferably less than 25%.
