Abstract

L'invention concerne un accumulateur à capsule anéroïde qui est particulièrement utilisé dans des circuits hydrauliques dans l'industrie automobile ou aéronautique à des fins de prévention de chocs, de réduction d'impacts et de sécurité. L'accumulateur comprend un corps de séparation qui est placé dans une chambre creuse définie par une enveloppe supérieure et une enveloppe inférieure et qui est relié aux deux enveloppes. L'enveloppe supérieure est constituée d'une buse et d'un couvercle, tandis que l'enveloppe inférieure est constituée d'un tube en métal plissé qui est relié à une bordure périphérique et à une paroi de séparation. Ledit corps de séparation comprend un premier séparateur relié de manière coaxiale à un ou plusieurs autres séparateurs. Chacun d'entre eux est formé d'un tube en métal plissé relié à un corps de soupape et à une paroi de séparation. L'accumulateur peut fonctionner dans une large plage de températures comprises entre 60 et 280 °C tout en présentant de bonnes propriétés d'absorption de chocs et de résistances aux impacts, ce qui a pour effet de prolonger sa durée de vie.
