Abstract: A reliable, compact, and efficient asymmetrical interference pulsation dampener is intended for the reduction of pulsation in hydraulic or pneumatic systems and their pressure head pipelines. Basic elements of the dampener are interference disks or combinations of rigid concentric cylinders, which divide the stream of a fluid or gas for the purpose of reducing the pulsation through negative interference. In relation to the central channel, the secondary channel of the dampener is made with a reduced section. The power wave balance at the merging point of the channels is established through the acoustic resonators built into the dampener.

Abstract: A composite interference pulsation dampener that has no moving parts, which results in the high reliability and efficiency of the dampener on wide intervals of frequencies, temperatures, pressures, and flow velocities.
