Abstract
(EN)
A seal comprising: an annular body defining an inner sidewall and an outer sidewall extending from a base; and a plurality of energizing elements disposed within a recess between the inner and outer sidewalls, wherein at least two adjacent energizing elements of the plurality of energizing elements have different unit loads as compared to one another, and wherein the at least two adjacent energizing elements contact the inner sidewall.
(FR)
Un joint comprend : un corps annulaire définissant une paroi latérale interne et une paroi latérale externe s'étendant à partir d'une base ; et une pluralité d'éléments d'excitation disposés à l'intérieur d'un évidement entre les parois latérales interne et externe, au moins deux éléments d'excitation adjacents de la pluralité d'éléments d'excitation ayant des charges unitaires différentes les unes par rapport aux autres, et les au moins deux éléments d'excitation adjacents étant en contact avec la paroi latérale interne.
