Patent ID: 11927292
Assignee: PERFORMANCE PULSATION CONTROL, INC.
Field: Mechanical elements (Mechanical engineering)
Classification: CPC F | IPC F

Claim 6:
7. A pulsation dampener, comprising:
a body having a first opening and a second opening, wherein the second opening is configured to provide fluid communication between an internal cavity of the body and a fluid flow external to the body;
a cover plate configured to close the first opening;
a flexible diaphragm held between the body and the cover plate by a seal area of the flexible diaphragm, the flexible diaphragm filled with a compressible material configured to dampen pressure pulsations within the fluid flow by allowing a portion of the fluid flow to enter the internal cavity through the second opening when a pressure of the fluid flow compresses the compressible material; 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.
