Abstract

Silent decompressor for gaseous fluids, of the type that includes a porous piece of revolution interposed in a conduit through the entire passage section of the latter and cooperating, on its surface upstream, with a covering element, such as a membrane, operated by pneumatic or hydraulic means, characterized in that the porous piece of revolution has a constant thickness in the axial direction, and is supported by a metal plate pierced by a multiplicity of holes regularly distributed and flowing into the downstream part of said duct, being the sum of the sections of the different orifices at least equal to the useful cross-section of the fluid through the porous piece when the covering element is fully raised.
