Title:
ENERGY ATTENUATION APPARATUS FOR A SYSTEM CONVEYING LIQUID UNDER PRESSURE AND METHOD OF ATTENUATING ENERGY
Document Type and Number:
WIPO Patent Application WO2002025164
Kind Code:
A9
Abstract:
An energy attenuation apparatus for a system conveying liquid under pressure is provided, wherein the apparatus is disposed in a liquid conveying line of said system. A restrictor (57) or tubing section (T) is disposed in a hose (54) and divides the interior thereof into an inlet chamber and an outlet chamber that communicate with one another. A first tuning cable (65) of polymeric material is disposed in the inlet chamber, with a first end of the tuning cable being connected to the inlet end of the inlet chamber for receiving liquid from the system, while a second open end (68) of the tuning cable (65) is spaced from the outlet end of the inlet chamber for conveying liquid thereto. A second tuning cable (66) of polymeric material is disposed in the outlet chamber, with a first end of the tuning cable being connected to the restrictor or tubing for receiving the liquid, while a second open end (69) of the tuning cable (66) is spaced from the outlet end of the outlet chamber for conveying the liquid thereto.
