CA 2174418

A rubber elastic sealing ring 13 is arranged between two concentric machine parts 11, 12 moved towards each other. The sealing ring 13 has a surface 22 that on the one hand ends in a dynamic sealing edge 21 and on the other hand extends to the low pressure side N. In addition, an outer peripheral surface 25 of the sealing ring 13 is inclined towards the bottom 18 of the groove in the non-compressed state of the sealing ring 13. Imaginary planes 35, 36 extend through the ring-shaped conical surfaces 22, 25. The imaginary planes 35, 36 are also conical ring-shaped surfaces that form an intersection line 37. The intersection line 37 is always located between one plane 34 (ring-shaped surface) and the peripheral surface 15 of the second machine part 12.

Un anneau d'étanchéité élastique en caoutchouc (13) est monté entre deux pièces concentriques (11, 12) d'une machine qui se déplacent l'une vers l'autre. L'anneau d'etanchéité (13) a une surface (22) qui se termine d'une part par un rebord dynamique d'étanchéité (21) et qui s'étend d'autre part jusqu'au côté basse pression N. En outre, une surface circonférentielle extérieure (25) de l'anneau d'étanchéité (13) s'étend obliquement jusqu'au fond de la rainure (18) à l'état non comprimé de l'anneau d'étanchéité (13). Les surfaces annulaires coniques (22, 25) sont traversées par des plans imaginaires (35, 36) qui sont eux aussi des surfaces annulaires coniques qui forment une ligne d'intersection (37). La ligne d'intersection (37) est toujours située entre un plan (34) (surface annulaire) et la surface circonférentielle (15) de la deuxième pièce (12) de la machine.
