<p>Power braking system comprising a pneumatic servo (19) associated with a master cylinder (2), the servo operating on a hydraulic reaction principle. Said servo comprises a movable pneumatic piston (5) carrying a control valve (7) actuated by a rod (8), and a partition (4) movable under the effect of a pressure difference and generating boosting power. The movable partition (4) is slidingly mounted in relation to the pneumatic piston (5) to act at an early stage on the master cylinder. The device of the invention provides enhanced braking power for a short control rod stroke.</p> |
