ABSTRACT:
A silencer including a hollow tube having, in the free state a predetermined inside diameter, the tube including a tube wall having a substantially uniform thickness, an interior surface, a hard exterior surface at least one groove extending axially of the tube, the groove having a depth that is less than the thickness of the tube wall and a slot in the wall extending axially of the tube, and at least one partially compressed high density polymeric open cell foam plug in the interior of the hollow tube, the plug having in the uncompressed state a substantially circular cross section in at least one plane, the circular cross section of the plug having an outside diameter sufficient to increase the inside diameter of the hollow tube to a diameter at least about 5 percent greater than the predetermined inside diameter of the hollow tube in the free state. The hollow tube portion of the silencer may be recovered from a used hollow photoreceptor drum, combined with a high density polymeric open cell foam plug and installed in a fresh hollow photoreceptor drum.
