Abstract

Ce mécanisme se compose essentiellement de deux pistons 3, 4 disposés en tandem dans un boîtier ou cylindre formé de deux coquilles 1, 2, de deux diaphragmes 7 et 8 et d'une soupape 5. Il peut être monté entre une pédale de frein agissant sur la tige de commande 22 et un maître-cylindre actionné par le poussoir 17, une dépression fournie par la tubulure d'admission ou une pompe à vide étant appliquée par la tubulure 16. Pour réduire la dimension axiale du mécanisme, les pistons 3 et 4 sont en tôle emboutie et la protubérance 20 formant le renfoncement 18 dans la coquille avant 1 peut s'emboîter dans la partie cylindrique 3B du piston avant 3 à la fin de l'avance des pistons.
