| (54) | A seal with joint protection |
| (57) 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). |
