Abstract
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.
Claims22
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;
- and
- wherein the exhaust gases flow through the inlet opening into the housing and form an outer vortex along the inside surface flowing toward the dead end, the direction of the flow of exhaust gases reversing in the dead end to flow back toward the live end and into the open end of the outlet pipe.
A muffler that receives exhaust gases from a combustion engine of a vehicle, the muffler comprising:
- an axially elongated housing having a live end defining an outlet opening and an inlet opening, a dead end axially spaced from the live end, and a tubular side wall having an inside surface;
- an outlet pipe extending axially from the outlet opening into the housing away from the live end forming an open end;
- a projection disposed in the dead end of the housing and extending axially toward the live end to create an area of low pressure adjacent the dead end;
- the inlet opening being provided adjacent the side wall of the housing between the live end and the open end of the outlet pipe;
- and
- wherein the exhaust gases flow through the inlet opening into the housing and form an outer vortex flowing along the inside surface toward the dead end, the exhaust gases are drawn into the area of low pressure and are expelled from the area of low pressure with the direction of the flow of exhaust gases being reversed to flow toward the live end and into the open end of the outlet pipe.
A muffler that receives exhaust gases from a combustion engine of a vehicle, the muffler comprising:
- a housing having a live end defining an outlet opening and an inlet opening, a dead end and a wall having an inside surface;
- an outlet pipe extending from the outlet opening 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;
- and
- wherein the exhaust gases flow through the inlet opening into the housing and flow in an outer vortex along the inside surface toward the dead end, the direction of the flow of exhaust gases reversing in the dead end to flow back toward the live end and into the open end of the outlet pipe.
