Abstract:
An apparatus for facilitating a reduction in fluid pressure and suppression of noise created by the reduction of fluid pressure, the apparatus comprising:a tubular inner sleeve defining a fluid flow axis and a plurality of inner sleeve passages extending radially therethrough relative to the axis, each of the inner sleeve passages having a tortuous configuration; a tubular outer sleeve having the inner sleeve concentrically positioned therein, the outer sleeve defining a plurality of outer sleeve passages extending radially therethrough relative to the axis; and a tubular muffler concentrically positioned between the inner and outer sleeves; wherein fluid flows radially outwardly through the inner sleeve passages, through the muffler, and through the outer sleeve passages, the muffler being oriented relative to the inner sleeve such that jets forming downstream of the inner sleeve passages will impinge the muffler prior to creating shockwaves.
