Abstract

Régulateur comportant un ressort de régulation en plusieurs parties. Le carter 1 comprend un alésage 2 à plusieurs gradins qui contient un piston 3 de soupape avec un elément de fermeture 4 coopérant avec un siège 5. L élément 4 a un alésage borgne 7 relié à un trou radial 8 débouchant dans une rainure annulaire 9 qui contient un joint torique 10 servant d'élément de fermeture. Des rainures de la face 11 empêchent l'application totale de l'élément 4 sur la pièce 12. La chambre 13 est reliée par le raccordement 14 à la tubulure de frein 15. La chambre annulaire 16 est reliée par le raccordement 17 à la tubulure de frein 18. Le piston 3 porte une cuvette 19 sur laquelle s'appuie l'extrémité du ressort 20. L'autre extrémité repose dans une douille 21 dont le fond 22 s'appuie à une came 23 d'un arbre 24 entraîné par le levier 25. Celui-ci est relié à l'essieu 26.Regulator comprising a regulating spring in several parts. The housing 1 comprises a bore 2 with several steps which contains a valve piston 3 with a closing element 4 cooperating with a seat 5. The element 4 has a blind bore 7 connected to a radial hole 8 opening into an annular groove 9 which contains an O-ring 10 serving as a closure element. Grooves on the face 11 prevent the total application of the element 4 on the part 12. The chamber 13 is connected by the connection 14 to the brake pipe 15. The annular chamber 16 is connected by the connection 17 to the pipe. brake 18. The piston 3 carries a cup 19 on which rests the end of the spring 20. The other end rests in a sleeve 21 whose bottom 22 rests on a cam 23 of a shaft 24 driven by lever 25. This is connected to axle 26.
