Abstract
A fluid seal for a liquid and gas-filled damper mechanism. The seal includes a casing and a primary lip body subdivided into two portions, one portion being adapted to provide a fluid seal with an associated reciprocable rod, and the other to provide a one-way relief valve action to bleed fluid from one side of the lip body to the other when higher pressure is on the rod side; and to increase the sealing force when the higher pressure is on the other side of the lip body opposite the rod.
