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.

A seal features a first ply and a second ply, each ply having at least one convolution. Leg termination regions connect the plies, such that a substantially enclosed volume is created between said first and second surfaces. Additional plies may be disposed between the first and second plies, the material of the additional plies having substantially the same convoluted shape of the first and second surfaces and being disposed within the envelope created between the first and second surfaces. The seal of the present invention may be formed of tube or strip stock. A seal formed of strip stock may have its edges, running about the circumference of the seal, either abutting, overlapping, or welded to each other.

A seal features a first curved region generally concave in a direction of concavity, and a second curved region generally concave in the direction of the concavity of the first curved region. The second curved region is oriented within the direction of concavity of the first curved region. A first bend connects the first curved region to the second curved region, and a second bend connects the first curved region to the second curved region.

A seal of single or multiple plies and/or single or multiple convolution regions features inflection regions to arrest or reduce bending stress in the seals acute bend regions and/or ply deformations on non-pressure-facing plies. Additionally, there is disclosed the combined use of multiple-ply seals incorporating the inflection regions in each ply and deformations on non-pressure-facing plies.

The present invention is directed to a resilient, annular, metallic seal member having a generally “j” shaped cross-section. The annular, metallic seal member includes a first end portion having a first distal end, a generally curled second end portion that extends to a second distal end, and a central body portion between and contiguous with the first and second end portions. The annular, metallic seal member has a first side and an opposite second side. The second end portion curls in a first direction in accordance with a predetermined radius such that the second distal end is located across from the first side of the annular, metallic seal member and the first and second distal ends do not face each other.

An annular, axial seal having a linear section having opposite ends, a first side in a first plane and an opposite second side in a second plane wherein the second plane is parallel to the first plane and a curled section contiguous with one of the ends of the linear section. The curled section curls in a first direction to a distal end. The curled section curls in the first direction in accordance with a predetermined radius and predetermined distance such that the distal end of the curled section is located directly across from the first side of the linear section. The linear section and the curled section provide a generally “J” shaped cross-section. The annular, axial seal also has a tip portion contiguous with the opposite end of the linear section such that the linear section is between the tip portion and the curled section. The tip portion is slightly curved with respect to the linear section such that the tip portion breaks the first plane. The tip portion has an end that does not directly face the distal end of the curled section.

A seal is inserted into a space to be sealed. First and second end portions of the seal are engaged with first and second end surfaces of the space. The seal is compressed between the first and second end surfaces. The compression strains the seal. The strain includes the rotation of a cross-section of the seal so as to bias the seal into engagement with a surface forming one of an inboard surface and an outboard surface of the space.
