Muffler with spark arrestor

摘要

A muffler includes a tubular body having an interior surface extending between a first end and an opposing second end, the interior surface bounding a chamber. An exhaust cap is disposed on the second end of the tubular body, the exhaust cap having an interior surface bounding a channel that communicates with the chamber. An inlet cap is disposed on the first end of the tubular body. A perf tube is longitudinally disposed within the chamber of the tubular body. A spark arrestor includes a tubular neck advanced within the channel of the exhaust cap toward the body. A spark barrier is mounted on an end of the tubular neck so as to be at least partially disposed within the perf tube, the spark barrier being comprised of a sheet of mesh or porous material.
