Abstract

Dans la soupape de retenue de construction simple et robuste, et avec amortissement progressif, un couvercle 5 coopérant avec le siège 8 est fixé sur un guide 4 en forme de cylindre ceux, monté de façon coulissante. Ce guide 4 est entouré par un piston annulaire 9. Des orifices d'étranglement 14, 15 sont prévus dans le guide 4, afin d'établir une liaison entre l'espace intérieur et les chambres 12, 13 adjacentes aux faces frontales 10, il du piston amortisseur 9. Application aux soupapes de retenue pour conduites de liquide.
