Abstract:
A seal assembly for sealing a high pressure fluid cavity from a low pressure fluid cavity, the cavities at least partially disposed between a hollow rotating shaft and a co-axial rotating shaft at least partially disposed within the hollow rotating shaft, is provided. The seal assembly comprises a pair of annular axially-spaced runners and an annular seal ring positioned axially between the runners. The annular seal ring has an axial dimension, a radial dimension, and a radially-outward facing surface frictionally engaged with a surface rotating with the hollow rotating shaft. The cross-sectional area at any point along the circumference of the annular seal ring is less than the product of the axial dimension multiplied by the radial dimension of the annular seal ring at that point along the circumference.

Claim (Index 17):
The seal assembly of  claim 16  wherein said annular seal ring further comprises one or more reinforcing ribs extending through the hollow portion of the O-shaped cross-section.
