Abstract
A sealing device for a hydraulic assembly wherein hydraulic fluid is contained in working chamber () formed between body () and thrust member () of the assembly. The device comprises annular seal () with opposed sealing faces which are urged into sealing engagement between body () and thrust member () which have convergent sealing faces. The device may also have a pressure relief valve () tapped into the over-stroke end of chamber () to protect seal () from over-stroke damage comprising porous body () which allows fluid to bleed from chamber () and allows seal () to pass the tapping point without obstruction.
