Title:
BRAKING DEVICE USING AN INTEGRATED MASTER-CYLINDER BRAKE BOOSTER
Document Type and Number:
WIPO Patent Application WO/2003/013925
Kind Code:
A1
Abstract:
The invention concerns a braking device essentially comprising a pneumatic brake booster (1) and a master cylinder (2), the brake booster including in particular a rigid shell (10), a mobile partition (11), front and rear chambers (101, 102), and a pneumatic piston (12), and the master cylinder (2) including in particular primary and secondary pistons (221, 222) defining primary and secondary pressure chambers (241, 242), and an actuating rod (23) controlling the primary piston (221). The invention is characterised in that the master cylinder is integral with the pneumatic piston (12) and mounted sliding in the front chamber (101), while the actuating rod (23) is hollow, integral with the rigid shell (10), and communicates with the primary pressure chamber (241), and the secondary piston (222) is sealingly traversed by a conduit (25) communicating with the secondary chamber (242), passing through the primary chamber (241) and the actuating rod (23), and fixed relative to the rigid shell (10).
