Resonance Suppression Device

摘要

A resonance suppression device for a first fluid containing duct (32) in which the fluid is capable of resonance. The device comprises means defining a second fluid containing duct (40) arranged in fluid communication with the first duct (32). The second duct (40) is formed such that fluid therein can resonate on resonance of the fluid in the first duct (32), thereby suppressing resonance in the first duct (32).
