ABSTRACT:
Braking device including a master cylinder (2), a primary piston (3), a control member (4), a booster (6) coupled to the control member (4), and an assist valve (VA) defined by a reaction piston (17) with a bore (18) therein for receiving a ratio control member (24). The control member (24) has a piston (29) with a head (25) located in a chamber (26) between the reaction piston (17) and a bushing (27) retained in the bore (18). The bushing (27) has an axial passage (28) that receives a head (25) of piston (29) to form a valve (36) for closing an inlet to a passage (30) in the piston (29). The bushing (27) slides within bore (18) to limit a pressure difference between the chamber (26) and a front part (18a) of the bore (18) to a value below a pressure difference that causes the valve (36) to open.
