Abstract

L'invention concerne un cylindre principal de freinage à pistons montés en série. Elle se rapporte à un cylindre principal de freinage qui comprend, dans un carter 20, un piston primaire 30 et un piston secondaire 44, séparés par un piston intermédiaire 38 comprenant une soupape 40 de dosage. Les pressions dans la région primaire 36, la région intermédiaire 42 et la région secondaire 48 sont égales lorsque la pression primaire ne dépasse pas une certaine valeur et, au-delà de cette valeur, la pression intermédiaire et la pression secondaire sont inférieures à la pression primaire. De cette manière, le freinage des roues avant 12 d'un véhicule est plus important que celui des roues arrière 14 pour un freinage important. Application au freinage des véhicules automobiles.
