Abstract

An energy attenuation apparatus for a system conveying liquid under pressure, and a method for attenuating energy are provided.
One embodiment (20K-200) includes tubular casing (57) having an inlet opening and an outlet opening. An inlet conduit (52) extends concentrically into the tubular casing (57) through the inlet opening, with an annular space (51) being formed between the inlet conduit (52) and the tubular casing (57). At least one aperture (53) for introducing liquid into the annular space (51) from the inlet conduit (52) is provided on a portion thereof in the tubular casing.
