Abstract: A silencer for silencing outlet pulses of compressed air, comprises an elongated housing provided with an inlet and an outlet. Fitted in the housing between the inlet and outlet, are at least two sound-absorbent elements each comprising a transverse member which extends from the longitudinal center line of the housing perpendicularly thereto and at least on two sides terminates at a distance from the housing, the transverse member has, at the end of those sides, a plate which is air impermeable and which extends essentially parallel to the longitudinal center line of the housing. The part of the baffle between the two sides extends up to the wall of the housing. The inlet and outlet open into the housing at locations spaced from the area defined between the plates, and the free cross-sectional surface area between the plates and the housing is less than 15% of the total cross-sectional surface area of the housing at the location of the plates.
