Abstract: Disclosed herein are pressure attenuator devices for rotating electrical machines, The pressure attenuation device contains a screen with a plurality of openings, wherein the screen is positioned within the internal cavity and configured to segregate a flame front propagating from an ignition source formed by a combustion process originated in the cavity. Thus, with the use of the pressure attenuation device, an expressive reduction of pressure inside the cavity of the rotating electrical machine is obtained.
