ABSTRACT:
A rotary valve noise attenuator with a rotary ball control element and a noise attenuator member mounted in the ball having multiple, elongated, substantially enclosed channels formed across the valve opening to split the flow stream into several smaller flow streams. The channel walls are perforated so each smaller flow stream is further dispersed and diffused into many minute flow streams after entering the channel. A noise attenuator constructed of several corrugated sections fixed crest to crest to form several diamond shaped channels across the valve opening each having four side walls with holes.
