Muffler with variable sound-absorbing characteristics

Gerhard Elfinger; Wolfgang Hahnl; Friedrich Wellner; Andreas Mayr; Klaus Spindler; Thomas Koehler; Hans Bussmann

A muffler for pulsating gases, especially exhaust gases of internal combustion engines, comprises a housing into which an inlet conduit enters, from which at least on outlet conduit exits and which is divided by at least one partition wall into at least two chambers. In this muffler the flow cross section of a flow path connecting two chambers and/or of an outlet conduit can be varied by means of an adjustable closure element. An actuating element acting on the closure element is provided in the region of the exit cross section of the inlet conduit.
