<p>A pulsation dampener (20) for receiving a fluid medium containing pressure pulsations. The pulsation dampener can include a body (22) having an inner surface (17), an inlet (24), and an outlet (26), and a fluid path (21) defined at least partially by the inner surface of the body. The fluid path can include a first chamber (27) in fluid communication with the inlet (24) and having a first cross-sectional area ( S 1 ), a second chamber (28) positioned adjacent the first chamber and having a second cross-sectional area ( S 2 ) different from the first cross-sectional area ( S 1 ), and a third chamber (30) in fluid communication with the outlet (26) and positioned adjacent the second chamber (28) opposite the first chamber (27) and having a third cross-sectional area ( S 4 ), different from the second cross-sectional area ( S 2 ). The fluid path can be configured such that the second cross-sectional area ( S 2 ) is greater than the first cross-sectional area ( S 1 ) and the third cross-sectional area ( S 4 ).</p> |
