A muffler is provided that air or gas flows through to attenuate acoustic oscillations and reduce sound levels. An inner vortex and an outer vortex are created within the device that reduce noise within the rotating flow of gases. The gases flow in the outer vortex from an inlet in a live end of the housing toward a dead end of the housing. A projection is provided in the dead end of the housing that creates a low pressure area that causes the formation of the inner vortex flowing from the dead end toward the live end to an outlet.
1. A muffler that receives exhaust gases from a combustion engine of a vehicle, the muffler comprising: an elongated housing having a live end defining an outlet opening, an inlet opening, an opposed dead end and a tubular side wall having an inside surface therebetween;an outlet pipe extending from the live end into the housing to an open end of the outlet pipe;the inlet opening being provided in the housing between the live end and the open end of the outlet pipe; andwherein the exhaust gases flow through the inlet opening into the housing and form an ...
