MASTER CYLINDER WITH DYNAMIC REACTION ADJUSTABLE BY CROSS-SECTION DIFFERENCE Russian patent published in 2003 - IPC

Abstract RU 2217334 C2

FIELD: transport engineering; vehicle brake systems. SUBSTANCE: proposed master cylinder with hydraulic reaction for pneumatic brake booster contains main piston 12 taking up auxiliary forces and hydraulic reactive device installed for sliding in said main piston and including pusher 3. said reactive devices take up control force. Novelty is that hydraulic reactive devices contain additionally central locking piston 4, stepped and hollow reactive piston 5, ratio changing piston 6 and three springs 71, 72, 73. At quick application of control force to pusher 3, it is exposed to action of counter- force proportional to difference between inner and outer cross-sections of reactive piston 5. EFFECT: improved efficiency of emergency braking owing to considerable reduction of force counteracting control force. 7 cl, 2 dwg
