ABSTRACT:
A muffler assembly particularly adapted to silence the exhaust air from an air valve of an air system. The muffler is constructed so as to permit effective silencing without significantly increasing valve and/or system response times. In addition, the design provides long life by permitting the retention of foreign matter in the exhaust air without significantly increasing the restriction to flow or decreasing the performance of the muffler. The muffler includes an inlet, an expansion chamber, a packing of woven material and an exhaust opening in that sequence.
