A seal assembly disposed within a radial seal groove to sealingly engage a bonnet within a bore. The seal assembly includes a radial seal surface, an axial seal surface, a vent surface, and an axial preload surface. The seal assembly is thrust towards a longitudinal wall and away from a radial wall of the radial seal groove when pressure in a high-pressure zone increases.

L'invention concerne un ensemble joint placé à l'intérieur d'une gorge de joint radial, de sorte à engager un chapeau dans un trou de sonde de manière étanche. L'ensemble joint présente une surface de joint radial, une surface de joint axial, une surface d'évent et une surface de précharge axiale. L'ensemble joint est poussé vers une paroi longitudinale et éloigné d'une paroi radiale de la gorge de joint radial, lorsque la pression régnant dans une zone haute pression augmente.
