ABSTRACT:
This boosted brake device comprises a pneumatic brake booster (1) associated with a master cylinder (2), the booster operating according to a hydraulic reaction principle and comprising a movable pneumatic piston (5) carrying a control valve (7) actuated by a rod (8), as well as a partition (4) which can move under the effect of a pressure difference and which develops a boost force.
The movable wall (4) is mounted slidingly with respect to the pneumatic piston (5) in order to act early on the master cylinder.
The device of the invention allows greater braking for small values of the travel of the control rod.
