A device for attenuating pulsation of a fluid in a piping system comprises fluid-branching pipes extending from the piping system in which there are pulsation waves, and a plurality of orifice elements and a plurality of discs disposed in a dispersed fashion and having a small reflection factor of the pulsation wave and having a total friction factor greater than that of the entire piping system, thereby providing the effect of attenuating the pulsation of the fluid within the system without increasing the resistance of the piping system without increasing power consumption.

A device for attenuating pulsation waves occurring in a piping system and caused by a fluid passing through a length of the piping system, which device comprises (a) at least one fluid branching pipe communicating with said piping system at a plurality of positions thereof for passing a partial flow

A device for attenuating pulsation waves occurring in a piping system and caused by a fluid passing through a length of the piping system, which device comprises (a) at least one fluid branching pipe communicating with said piping system at a plurality of positions thereof for passing a partial flow of said fluid, and returning said partial flow to said fluid through through said fluid branching pipe, said fluid branching pipe having flow passage zones which are separated acoustically from said piping system except for said plurality of positions, and (b) acoustic damping means comprising a plurality of orifice means and/or disc means having an overall percentage of opening area of 40% or more in said fluid branching pipe, said fluid branching pipe being thus open for passage of fluids.
