A pulsation dampener for receiving a fluid medium containing pressure
pulsations. The pulsation dampener can include a body having an inner
surface, an inlet, and an outlet, and a fluid path defined at least
partially by the inner surface of the body. The fluid path can include a
first chamber in fluid communication with the inlet and having a first
cross-sectional area, a second chamber positioned adjacent the first
chamber and having a second cross-sectional area different from the first
cross-sectional area, and a third chamber in fluid communication with the
outlet and positioned adjacent the second chamber opposite the first
chamber and having a third cross-sectional area different from the second
cross-sectional area. The fluid path can be configured such that the
second cross-sectional area is greater than the first cross-sectional
area and the third cross-sectional area.
