Zusammenfassung:A static mixer for exhaust gas ducts of internal combustion engines includes an elongated hollow metal body having a shape which, relative to a symmetry axis, substantially corresponds to a solid of revolution defining at its inside a cavity having opposite bases, at least one of which has an axial opening, and a closed lateral wall connecting the opposite bases and having at least one radial opening over which a concave blade is arranged extending radially outward from a portion of the peripheral edge of the radial opening and surrounding a portion of the radial opening so as to define, in a first angular direction relative to the symmetry axis, a corresponding concave screen or spoon and, in a second, opposite direction, a mouth intended for the passage of gases and located substantially in front of the concave screen or spoon.
