Abstract

A compact low-resistance muffler for reducing sound levels generated by the pulsatile flow of fluids as, for example, at the intake of a compressor or the exhaust port of an internal combustion piston engine. The muffler or suppressor comprises a pair of adjacent branch passages having a common inlet trunk and a common outlet trunk, one of the branch passages containing a flow-restricting orifice and the other of such branch passages being free of any such restriction.
