Abstract

The invention concerns a device for expanding a compressed gas, comprising a tube (3) supplying the gas to be expanded, an elongated sheath (1) containing a lining (2) made of a sound damping material, one end of said sheath communicating with the tube (3) through a series of holes (5), its opposite end emerging laterally outside through a series of orifices (4) exhausting the expanded gas, the total surface of said orifices being significantly greater than that of said holes, such that the gas passes through the latter at sonic velocity and its velocity upstream of its inlet is maintained at subsonic level. The elongated sheath (1) extends, by being fixed thereto, over the entire length of said tube (3) while being closed at its end opposite the one through which the gas to be expanded enters, and said series of orifices (4) enabling the expanded gas to be exhausted outside being provided laterally and on either side continuously over its entire length.
