Classification: CPC F | IPC F

Claim 0:
1. A pulsation dampener, comprising:
a body having an internal cavity and a first opening and a second opening;
a cover plate configured to close the first opening, wherein the second opening provides fluid communication between the internal cavity and a fluid flow external to the body;
a flexible diaphragm held by a seal area, in compression between the body and the cover plate, the flexible diaphragm configured to allow at least a portion of fluid from the external fluid flow to enter the internal cavity through the second opening when a pressure of the external fluid flow exceeds a pressure in the flexible diaphragm, wherein at least a portion of the flexible diaphragm contacts the portion of fluid from the external fluid flow that has entered the internal cavity; and
a diaphragm radial compression ring fitted to the seal area of the flexible diaphragm,
wherein the diaphragm radial compression ring comprises an annular cylinder with an upper portion having uniform thickness and a lower portion that is tapered, and
wherein the diaphragm radial compression ring has a beveled upper inner edge.
