Abstract

Garniture à manchettes d'étanchéité en forme de toit installée entre deux pièces mobiles l'une par rapport à l'autre dans la direction axiale (A). La manchette (4) a deux branches (14, 16) s'écartant l'une de l'autre en forme de V, une branche comporte une lèvre d'étanchéité (13). Partant de la lèvre d'étanchéité (13), une première surface d'étanchéité (11) côté basse pression fait un premier angle (al) par rapport à l'axe (A) de la manchette et une seconde surface d'étanchéité (12) fait un second angle (α2) par rapport à l'axe (A). Le premier et le seconde angle sont chacun supérieur à 0° et inférieur à 90° ; le premier angle (α1) est inférieur au second angle (α2).Roof-shaped sleeve packing installed between two parts movable relative to each other in the axial direction (A). The sleeve (4) has two branches (14, 16) moving away from each other in a V-shape, one branch has a sealing lip (13). Starting from the sealing lip (13), a first sealing surface (11) on the low pressure side makes a first angle (a1) with respect to the axis (A) of the sleeve and a second sealing surface ( 12) makes a second angle (α2) with respect to the axis (A). The first and second angles are each greater than 0 ° and less than 90 °; the first angle (α1) is less than the second angle (α2).
