Abstract
A new and improved pulsation dampener or surge absorber having an improved diaphragm or bladder is disclosed. The diaphragm is disposed within a pressure vessel for forming two non-communicating zones. The first zone communicates with the fluid having the undesired pulsations or surges while the second zone is precharged to a desired pressure level with a compressible fluid. The pressure vessel is secured with the conduit having the pulsating fluid and the diaphragm is disposed within the pressure vessel for preventing contact of the fluid having the pulsation with the pressure vessel to prevent corrosion of the pressure vessel. The inlet nozzle for the fluid having the pulsation which is subject to flow erosion as well as corrosion can thereby be replaced without replacing the pressure vessel securing means. The diaphragm is of the reverse folding type and is provided with shock absorber means on an inlet bridging disk to protect the diaphragm when the pulsating fluid pressure is reduced.
