Filed:

May 24, 2001

Appl. No.:

09/863353

Inventors:

Horace P. Halling - Durham CT
Paul L. Porter - Colbert WA

Assignee:

Jetseal, Inc. - Spokane WA

International Classification:

F16J 1502

US Classification:

277626, 277614, 277644, 277647, 277314

Abstract:

A resilient seal has an annular curved region having a generally C-shaped cross section, and a pair of annular leg regions. Each leg region has a free end and extends generally radially inward towards the inside of the C-shaped cross section. The leg regions contact each other and each form a generally frustro-conical disk spring member extending inwardly from the curved region. The leg regions are adapted to contact each other and to provide a restoring force when the sealing ring is compressed. A first bend connects one of said leg regions to the curved region, and a second bend connects the other of the leg regions to the curved region.
