This invention relates to mufflers for silencing noise created by exhaust gases emanating from internal combustion engines. The muffler comprises an enclosed casing of tubular form including a peripheral wall, an inlet pipe and an outlet pipe wherein at least the inlet pipe extends into the casing and the end of the inlet pipe disposed within the casing has an elongate aperture to direct gas leaving the inlet pipe into the interior of the casing.

A muffler of the dissipative type comprising an enclosed casing having three side walls arranged to form a triangular tube means and closed by a pair of end walls, the interior surfaces of said side walls being smooth and unobstructed, an inlet means including at least one inlet pipe extending through one of said end walls and so shaped as to provide a reduced narrow walled end portion terminating in a narrow slit extending in a plane intersecting the direction of movement of gas through said inlet pipe and intersecting a plane normal to said direction, the pipe disposed relative to one of said side walls so that gas passes through said inlet pipe and impinges Upon the said one wall of said tube, an extension of of the line of the slit intersecting the plane defined by said one side wall so that said gas is reflected to a side wall adjacent to said one wall and to successive adjacent side walls of said triangular tube in a circumferential flow while moving toward one of said end walls, said triangular tube means being so shaped as to encourage the successive reflection of said gas from said adjacent walls, and outlet pipe means extending through an end wall through which gas passes out from the casing.
