The noise suppressor comprises a nozzle (31). The inlet of the nozzle is connected to the outlet of the compressor. The compressor's outlet merges into an expansion chamber (32) with a largest diameter ("d") greater than the largest inlet diameter ("e") of the nozzle. The chamber has an outlet formed by a second nozzle (33) identical to the first nozzle.
