FLUID PULSATION REDUCTION DEVICE

摘要

A pulsation damping device capable of damping pulsation of a plurality of frequencies and being reduced in overall size, wherein a first container (14) is disposed on the tip end side of a first connection pipe (13) connected to a pipe (3) so as to form a first pulsation damping device (12) with the first connection pipe (13) and the first container (14), a second connection pipe (16) is connected to the first container (14) and a second container (17) is connected to the tip end side of the connection pipe (16) so as to form a second pulsation damping device (15) with the second connection pipe (16) and the second container (17), and the first and second pulsation damping devices (12) and (15) are series-connected.
