A gas pressure regulator comprises a central body having a first, gas inlet pipe and a second, gas outlet pipe; a shutter housed at least partially in the central body and mobile to adjust the opening of a section for the passage of the gas between a position (B) in which the section is fully open and a position (A) in which the section is closed; a silencing device located in the central body at the passage section, for reducing the noise created by the passage of the gas; and means for fastening the silencing device to the central body. The silencing device comprises a cylindrical perforated plate to allow the passage of the gas. |
