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 9):
A seal assembly for sealing a high pressure fluid cavity from a low pressure fluid cavity, said 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, the seal assembly comprising:\n a pair of annular axially-spaced runners carried by an outer surface of said co-axial rotating shaft, each of said runners having an axially-facing radially-extending side surface opposing an axially-facing radially-extending side surface of the other runner; and an annular seal ring positioned axially between said opposing side surfaces of said runners, said annular seal ring having a radially-outward facing surface frictionally engaged with a surface rotating with the hollow rotating shaft; wherein said annular ring defines one or more interior channels extending arcuately through at least a portion of said annular ring.
