Abstract:
An energy attenuation apparatus for a system conveying a liquid under pressure is provided. The apparatus includes a liquid-conveying unit (23) or the like that includes three chambers (39, 40; 58; 59; 64; 55, 66) disposed in series. At least one of the chambers (58; 55, 66) contains no tube.
