Abstract

Amplificateur hydraulique. Dans un boîtier est définie une chambre de pression. Un piston mobile est soumis à la pression régnant dans la chambre de pression. A l'intérieur du piston est définie une chambre de réserve de pression. Une soupape est disposée dans un passage du piston pour contrôler l'écoulement de fluide entre la chambre de réserve et la chambre de pression. La soupape comporte un ensemble unitaire ayant un fourreau engagé de façon étanché dans le passage du piston. Un élément de fermeture est sollicité élastiquement contré un épaulement défini dans le fourreau. Une tige supportant un deuxième élément de fermeture traverse un passage dans le premier élément de fermeture. La soupape est susceptible d'etre commandée à l'ouverture soit par un élément d'actionnement commandé manuellement, soit en cas de pression excessive dans la chambre de réserve. Application au freinage assisté.
