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

Claim 12:
13. A method of improving sealing for a pulsation dampener including a body having an internal cavity and a first opening and a second opening, wherein the second opening providing fluid communication between the internal cavity of the body and a fluid flow external to the body, a cover plate closing the first opening, and 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, the method comprising; and
fitting a diaphragm radial compression ring to the seal area of the flexible diaphragm, between the body and the cover plate, to increase a sealing force sealing the internal cavity by compression of the seal area of the flexible diaphragm between the cover plate and the body
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.
