Abstract
A seal assembly for a groove or seal gland in a relatively displaceable machine part for sealing an axial machine part extending therethrough comprises a pair of annular seal elements and a support element disposed between the annular elements and radially extending wall of said groove. The annular seal elements have an axial slot therein and a key portion extending therefrom, shaped to engage the axial slot. The seal elements are arranged in an inverted nesting relationship to provide superior sealing characteristics when biased toward the machine part by said support element.
