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.
Claims21
A seal, comprising:
- an annular first curved region having a generally C-shaped cross section;
- a pair of annular leg regions;
- a first bend connecting one of said leg regions to said first curved region;
- and
- a second bend connecting the other of said leg regions to said first curved region;
- wherein each said leg region has a free end and extends generally radially inward towards the inside of the C-shaped cross section.
A seal, comprising:
- an annular curved region having a generally C-shaped cross section;
- and
- a pair of generally frustro-conical spring members extending inwardly from said curved region and adapted to contact each other and to provide a restoring force when the seal is compressed.
A seal, comprising:
- an annular curved region having a generally C-shaped cross section;
- and
- a pair of annular leg regions extending from said C-shaped cross section generally radially inwards towards the inside of the C-shaped cross section, wherein when the seal is compressed, an internal stress area exists in each leg region which has a stress greater than a maximum stress present in the curved region.
