Abstract

L'invention concerne un dispositif de limitation de débit unidirectionnel (1) comportant : - une chambre hydraulique (20) ; - un piston (2) présentant au moins un passage primaire (30) et un passage secondaire (32) d'écoulement du fluide ; ledit piston (2) étant monté coulissant selon un axe X à l'intérieur de la chambre hydraulique (20) entre une position plein débit et une position de limitation du débit ; - ledit dispositif de limitation de débit unidirectionnel (1) comportant un élément de retenue (36) qui est ménagé dans une paroi cylindrique (22) délimitant radialement la chambre hydraulique et fait saillie radialement en direction de l'axe X à l'intérieur de la chambre hydraulique (20), ledit piston (2) comportant au moins une portion de retenue (34) qui est logée entre l'élément de retenue (36) et un épaulement (23) ménagé dans la paroi cylindrique (22) de manière à assurer une retenue du piston (2) dans la chambre hydraulique (20).
