Abstract

Régulateur de force de freinage proportionnelle à la charge, comportant un piston régulateur gradateur, une valve relais logée dans le même corps et alimenté par la pression d'un réservoir, et une valve de précommande pour l'ajustage du début de la régulation de pression en fonction de la charge. La valve relais 8 est séparée fonctionnellement et branchée en aval de la valve 5 de régulation de la pression de freinage proportionnelle à la charge. Le poussoir 66 est monté avec étanchéité dans la valve relais 8, qu'il traverse.Braking force regulator proportional to the load, comprising a dimmer regulator piston, a relay valve housed in the same body and supplied by pressure from a reservoir, and a pre-control valve for adjusting the start of pressure regulation depending on the load. The relay valve 8 is functionally separate and connected downstream of the valve 5 for regulating the brake pressure proportional to the load. The pusher 66 is mounted with sealing in the relay valve 8, which it passes through.
