Abstract
A pulsation dampener includes: a centerbody assembly having: a chamber including a first opening bounded by a wall defining a first surface; an outlet port communicating with the chamber; an inlet port communicating with the chamber; a flexible first diaphragm, wherein a perimeter of the first diaphragm is bonded to the first surface forming a seal that blocks the passage of fluid; a first cap disposed adjacent the first diaphragm, defining a first cavity between the first cap and the first diaphragm; an inlet orifice formed in the first cap communicating with the first cavity; an exhaust orifice formed in the first cap communicating with the first cavity; and a valve seat disposed in the first cavity in fluid communication with the exhaust orifice. The first diaphragm is moveable between an open position spaced away from the valve seat, and a closed position sealed against the valve seat.
