<p>The present invention relates to a method reducing the pressure and pulsant energy of high-pressure fluid and a device thereof, especially to some kinds of mufflers. Said device has a guiding fluid cover in a flow pipe. Said cover can change the fluid flow direction parallel to a geometric central axis of the flow pipe, and divide the fluid into a plurality of branch streams which form a certain angle there between. The branch streams centripetally flow toward the both sides of a longitudinal symmetric plane, and strike each other or strike the outside wall of the next guiding fluid cover. Alternatively, the branch streams centrifugully flow away form the both sides of a longitudinal symmetric plane, and strike the pipe wall of the next guiding fluid cover or the flow pipe.</p> |
