Abstract

Dispositif de dosage de freinage permettant de limiter et de doser l'application de la pression de freinage aux roues d'un véhicule dans certaines conditions. Des tensions de ressort et des rapports tension-fléchissement de ressort permettent d'exercer une force différentielle sur une soupape de dosage et d'assurer une programmation linéaire ou non de la pression du fluide servant au freinage. Application aux dispositifs de freinage des véhicules automobiles.Braking metering device for limiting and adjusting the application of brake pressure to the wheels of a vehicle under certain conditions. Spring tensions and spring stress-to-deflection ratios exert a differential force on a metering valve and provide linear or non-linear programming of the brake fluid pressure. Application to motor vehicle braking devices.
