1. A SEAL WITH JOINT PROTECTION, of preferable application to the valves of the containers of pressurized gas, specially for oil liquefied gas containers, constituted by an inner body which is formed by a base from which starts up perimetrically a plurality of nerves which by their upper edge are weakly linked to an intermediate ring characterized in that one of the mentioned nerves (9) of the inner body comprises a section which is approximately twice the corresponding one to any of the remaining nerves (4), being this main nerve (9) linked in a joint way to the mentioned intermediate ring (8), whereas such intermediate ring (8) is weakly linked by its external edge to an outer body (11) through a series of linking points (10) uniformly distributed along the perimeter of such edge except in a wide arch confronted to an area (12) of joint link between both intermediate ring (8) and the outer body (11), being the mentioned area (12) located in a position diametrically opposed to the linking of the intermediate ring (8) with the main nerve (9). <IMAGE> |
