Technical Examples

Disclosed is a seal assembly for dynamically sealing between rotatable members, such as employed to seal the rolling cone of a rock bit. One preferred assembly includes an energizer, first and second seal rings, and a cushioning ring having an L-shaped cross-section disposed about portions of one of the seal rings to seal and absorb impact loads and thereby protect the more-rigid seal rings.
