The silencer device set forth herein in its various embodiments consists of at least one channelling bounded by at least one turn of a flat spiral, or of a cylindrical helix, or of a tapered helix, which may be blanked-off or open at one of its ends or at both of its ends, and/or incorporate radial holes or frontal holes in one or both faces. The outermost turn of the spiral, or the outermost surface of the helix, may either provide the shell of the device, or form a part thereof.

Silencer device for exhaust and high velocity gases, comprising an enclosure provided with an inlet pipe and a tail pipe, and means defining at least one channel within the enclosure having a curvilinear axis along which gases are directed from said inlet pipe, said enclosure further including at least one sound-wave interference chamber in communication with and formed by side wall means connected to extend between said channel and said tail pipe; said channel being open at both ends thereof and being defined by a sheet of metal rolled into a spiral; an outermost turn of said spiral being cylindrical and secured to an adjacent inner turn of the spiral to form the shell of the device; a capping ring provided with radially-extending support ribs and a central hole, said ring being fixed to the ends of innermost turns of the spiral at the inlet end thereof; a central chamber formed with the center of said spiral in communication with said channel and with the inlet pipe through said central hole; an opposite end of said chamber being closed by a disc baffle having radial support arms; a front cover fitted to the outermost turn of the spiral at said inlet end to establish a front sound-wave interference chamber between the cover and the spiral channel.
