The first valve seat (28a) is concentric with the second valve seat (20a) and a smaller diameter. The annular front face (40) of the valve element (36) is able to move in the tubular rear part (22) of the movable wall (12) and sealed therein by outer and inner edges. The annular front face (40) of the valve (36) has a least one opening (46) causing a chamber (44) to be situated behind the annular front face (40) of valve (36) to communicate with a space (35) situated between the first valve seat (28a) and the second valve seat (20a).

    • A boosted braking device for a motor vehicle having a master cylinder (200) and a pneumatic booster (100) operated by applying an input force to an operating rod (26). The booster (100) has a rigid casing (10) which is divided by a partition (16) into at least first (12) and second (14) leaktight chambers. The partition (16) is acted upon via a difference in pressure between the first (12) and second (14) chambers on the opening of a three-way valve (24) to allow pressurized fluid to be communicated to the second chamber (14). A main hydraulic piston (30) which is located in the master cylinder (200) has a hollow cylinder (32) which is in communication with an interior volume (V) of the master cylinder (200). A secondary hydraulic piston (34) slides in a leaktight fashion inside of the hollow cylinder (32). The secondary hydraulic piston (34) includes a two-way valve (56) which is normally open but interrupts communication between the interior volume (V) of the master cylinder (200) and an interior volume (35) in the hollow cylinder (32) when a variation in an input force is greater than a predetermined value. The secondary hydraulic piston (14) is composite and includes a first part (50) and a second part (52). In a rest position, the first part (50) abuts the hollow cylinder (32) under the effects of a first elastic force from a first elastic member (46) while the second part (52) is capable of sliding with respect to and abut the first part (50) under the effects of a second elastic force from a second elastic member (54,92).
