Abstract
A sound suppressing fluid handling device wherein a relatively high pressure fluid is conducted through a substantial pressure drop, relatively noiselessly, by passage of the fluid through a myriad of tortuous energy dissipating passages formed between adjacent turns of and opening through the ends of a sound suppressing reel comprising a relatively thin flexible spirally wound band. The preferred inventive embodiment described is a valve comprising a stack of annular discs seating coaxially against the inlet end of the sound suppressing reel and containing passages, formed partly between adjacent discs, for conducting the incoming high pressure fluid from the central opening in the disc stack to the inlet ends of the reel passages.
