Abstract

Dispositif destiné à obturer un accumulateur à vessie. Il comprend un obturateur ou piston creux 30 logé dans un corps 26 et tendant à être déplacé par un ressort 28 vers une position d'ouverture dans laquelle il permet à des substances contenues dans une chambre 12 d'un accumulateur 10 de s'écouler en passant dans des ouvertures 68 et à l'intérieur du ressort 28, sans contact avec ce dernier. Domaine d'application : accumulateurs d'huile sous pression, etc.
