ABSTRACT:
A pulsation dampener for dampening undesired pressure surges in a fluid comprising a pressure vessel having a first zone for receiving a fluid under pressure, a second zone having a compressible fluid therein at a preselected pressure and a third zone in communication with the second zone having a compressible fluid therein at a preselected fluid pressure greater than the preselected fluid pressure of the second zone. The pulsation damper can be designed as a supplemental pressure vessel to be added to conventional dampeners. The pulsation dampener can include a magnet assembly valve.
