Abstract
A seal assembly for a groove or seal gland in a relatively stationary machine part for sealing an axially displaceable machine part extending therethrough comprises a relatively flexible seal element supported by a relatively rigid support element. The seal element has a static seal that bears on a radial wall of the seal gland to provide superior back-pressure relief while maintaining proper seal element position in the seal gland.
