Abstract

Dans un élément de soutien pour un cylindre à compensation de flexion, à équilibrage de pression ou à réglage de pression, interposé entre un support fixe 2 et une enveloppe 3 de cylindre tournant autour du support et prévu pour absorber une force s'exerçant en direction radiale à partir du support vers l'enveloppe du cylindre par l'intermédiaire de sa partie de tête 5 et par l'intermédiaire d'une pellicule de liquide présente entre cette partie de tête et l'enveloppe du cylindre. Il est ménagé, au-dessous de la partie de tête 5, une cavité 8 qui est surmontée en pont par la partie de tête, de telle sorte qu'un flux de la force transmettre soit dirigé vers la partie de tete, en dehors de la ligne d'action 4 de la force, tout autour de la cavité 8. Par cette déviation du flux de force, la partie de tête formant pont est adaptée élastiquement à une éventuelle augmentation du rayon de l'enveloppe du cylindre
