A muffler for exhaust systems of internal combustion engines, pneumatic tools and the like, in which at least two parallel conduction channels are provided each having a conducting device for applying a torque about the channel axis for the entering partial flow of gas only along a short upstream initial section thereof, but is free of any components along the remainder of its length, the conduction channels being so arranged at their downstream ends that the partial flows of the gas come together from opposite directions and then flow together to a common outlet.

A muffler for an exhaust system of an internal combustion engine, a pneumatic tool and the like, comprising a casing containing at least two spaced parallel conduction channels comprising pipe elements extending in a downstream direction from an entrance chamber provided in said casing for the sound-carrying gas stream of the exhaust system, each said channel having a conducting device mounted therein adjacent said entrance chamber and extending a short distance downstream of said channels, each said device having means for applying a torque to the partial flow of the entering gas about the longitudinal axis of each said channel, each said channel being free of any components along the remainder of its length, and a separate gas collecting chamber in said casing located between said pipe elements at their dOwnstream ends, means closing said pipe elements at said downstream ends, and means adjacent said ends comprising through openings in said pipe elements and facing each other and opening into the gas collecting chamber to permit the partial gas flows therein to unite from opposite directions and to thereafter flow together into a common outlet chamber provided for the system, a third pipe element being located between said conduction channels, said third pipe extending through said entrance chamber and opening into said collecting chamber and an outlet chamber respectively at its opposite ends for draining the united partial gas flows from said collecting chamber.
