Abstract
This brake-booster device comprises a pneumatic brake-booster (1) associated with a master cylinder (2). The booster comprises a movable pneumatic piston (5) bearing a valve (7) and functions according to a hydraulic reaction principle, the hydraulic piston (11) of the master cylinder comprising in fact a hollow movable cylinder (13) receiving a boost force, and a secondary hydraulic piston receiving an input force, these two forces constituting the total actuation force. A helical spring (22), exerting an adjustable resilient force, is disposed between the secondary hydraulic piston and the movable cylinder so as to permit the adjustment of the non-zero minimal value of the actuation force.
