Abstract
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.
