A method and apparatus for installing seals in an interference fit with a comating sealing surface by initially stretching the seal (37) installed in a groove (15) to reduce its cross-sectional thickness perpendicular to a comating sealing surface (Fig. 4). The stretched seal (37) is mated with a comating surface and then relaxed, permitting the seal to return to an unstretched position (Fig. 3) and to passively assume a preloaded position against the comating sealing surface. The seal (37) may be repeatedly disengaged and reengaged by selectably restretching the seal (37) and then selectably releasing it upon completion of repositioning.
L'invention concerne un procédé et un dispositif destinés à l'installation de joints d'étanchéité dans un joint à ajustement serré possédant une surface d'étanchéité de contact. Ce procédé consiste à tendre le joint (37) installé dans une rainure (15) afin de réduire son épaisseur en section transversale perpendiculaire à une surface d'étanchéité de contact (Fig. 4). Le joint (37) tendu est mis en contact avec une surface correspondante puis détendu, ce qui permet au joint de retrouver sa configuration initiale (Fig. 3) et de prendre passivement une position préchargée contre la surface d'étanchéité correspondante. On peut retirer et remettre le joint (37) en place de façon répétée en tendant le joint (37) puis en le relâchant sélectivement lorsqu'il a été remis en place.
