Abstract

Soupape avec ressort à grand déplacement qui est soumis à une précontrainte telle qu'il n'agit qu'après ouverture de l'admission La soupape 1 est raccordée en 3 et 4 à l'alimentation en 5 et 6 au frein 7 et 8 et en 9 à l'air extérieur. Les soupapes à double siège 10 et 11 ont un siège de sortie 11, 12 sur un piston d'équilibrage 14, et un élément de fermeture 15, 16 poussé par un ressort 15', 16'. Le piston 17 porte le siège d'admission 18 de la soupape 10 et il est actionné par le poussoir 19, par l'intermédiaire d'une pièce 20 et d'un ressort à grand déplacement 22. Le siège 23 de la soupape 11 est solidaire du carter. La pièce 20 présente un téton 26 qui traverse la paroi 25 du piston 17 et porte un écrou vissé 28. La bride 29 de la pièce 20 s'appuie au ressort 22 par l'intermédiaire de la rondelle 30 et sert, avec l'écrou 28, au réglage de la précontrainte du ressort.Valve with large displacement spring which is subjected to a preload such that it acts only after opening the inlet Valve 1 is connected at 3 and 4 to the supply at 5 and 6 to the brake 7 and 8 and in 9 to the outside air. The double seat valves 10 and 11 have an outlet seat 11, 12 on a balancing piston 14, and a closing member 15, 16 pushed by a spring 15 ', 16'. The piston 17 carries the intake seat 18 of the valve 10 and is actuated by the pusher 19, through a part 20 and a large displacement spring 22. The seat 23 of the valve 11 is integral with the housing. The part 20 has a stud 26 which passes through the wall 25 of the piston 17 and carries a screwed nut 28. The flange 29 of the part 20 rests on the spring 22 by means of the washer 30 and serves, with the nut 28, adjusting the spring preload.
