Abstract

Dispositif comprenant une enveloppe dans laquelle le liquide atteint un niveau déterminé au-dessus duquel se trouve un coussin d'air, une canalisation d'arrivée et une canalisation de départ étant raccordées à cette enveloppe Un élément de transition 2 s'élargissant en diffuseur raccorde la canalisation d'arrivée 3 à l'enveloppe 1 et une plaque perforée 5 disposée à l'extrémité de l'élément de transition 2, sur la totalité de sa section transversale, comporte des canaux de répartition parallèles 6 comprenant des tronçons s'élargissant en gradins dans le sens de la circulation. Application en particulier aux arrivées de pâte des machines à papier pour amortir les vibrations provoquées par les pompes ou les canalisations mal posées et perturbant la formation de la feuille de papier.
