Abstract
A seal assembly includes first and second seal elements configured to lie adjacent to one another with a lower portion of each one disposed in a groove and an upper portion of each one projecting above the groove. The groove has a length disposed transverse to the direction of relative motion of a housing and a moving member and is located in the housing. The seal elements are further configured so that a contact surface of the upper portion of each seal element abuts the moving member and configured to allow independent movement of each seal element relative to each other in a direction transverse to the groove length. The seal elements are shaped to define a lubrication channel therebetween that is configured to allow the passage of a lubricant therein so as to lubricate motion of the seal elements relative to each other and relative to the moving member.
