Abstract

L'invention concerne un dispositif de contrôle de la pression d'un fluide du type à soupape contrôlé par inertie pour interrompre le passage du fluide d'un maître-cylindre aux cylindres des roues, lorsque la bille est soumise à une décélération qui dépasse une valeur prédéterminée. Il comporte un by-pass pour permettre le passage direct du fluide d'une chambre de soupape dans une chambre d'évacuation, la chambre de soupape communiquant avec une chambre d'admission et contenant la bille, ainsi qu'une soupape de retenue dans le by-pass pour interrompre normalement le passage direct du fluide de la chambre à soupape à la chambre d'évacuation, ladite soupape de retenue étant ouverte pour permettre le passage direct pour une différence de pression entre la chambre à soupape et la chambre d'évacuation, après fermeture de la soupape contrôlée par inertie Application aux systèmes de freinage de véhicules automobiles.
