ABSTRACT:
A pulsation dampener device particularly adapted for the efficient dampening of pulsations over a wide frequency range. The device is characterized by the ability to operate over a high temperature range and be operable when contacted by corrosive and like aggressive fluids within which pulses are generated. The device includes a pressure vessel which is cylindrical in section, a piston member shiftable axially within the vessel and dividing the same into a gas chamber and a fluid chamber, the piston incorporating a deflectible diaphragm disposed within a permeable cage whereby dampening may be effected by either or both of a bodily movement of the piston within the vessel or by deflecting movements of the diaphragms within the cage.
