Abstract
A sealing joint comprises, compressed between two parts, a stack of flexible strips separated by offset supports (9); an envelop (1) surrounds this structure (7) and ensures its sealing. Under compression, the strips distort around the supports becoming very stiff for little distortion. Thus, we can rightly be wary of the consequences regarding the relief of strain on the material, notably at high temperatures.
Claims19
A sealing joint comprising an external metal casing (1) and a flexible internal structure, the internal structure being made of flexible strips (8, 8a, 8b, 8c, 8d), overlaid and separated by supports (9, 9a, 9b, 9c, 9d), the supports located on either side of the strips being staggered, wherein the strips are spring plates having an elastic limit, and the supports comprise blocks which are laid out in rows, the rows extending in a first direction which is perpendicular to the strips, the blocks occupying every other space between the strips along the rows and being present at every second row in a second direction which is parallel to the strips, the sealing joint being compressible until the spring plates come to mutual contact between pairs of the supports below the elastic limit.
