Abstract

Amplificateur hydraulique. L'amplificateur comporte un boîtier avec un orifice d'entrée, un orifice de sortie et un orifice d'évacuation, et une chambre de pression. Une valve à tiroir disposée dans un alésage du boîtier et susceptible d'être actionnée par un opérateur, contrôle la communication entre les différents orifices. Une portée de la valve à tiroir coopère avec jeu minimum avec une portée de l'alésage pour filtrer les particules en suspension dans le fluide sous pression qui suinte dans l'alésage, afin de prévenir un risque de coincement de la valve à tiroir. Application aux amplificateurs de freinage.
