Summary:PCT No. PCT/FR95/01664 Sec. 371 Date Jan. 16, 1996 Sec. 102(e) Date Jan. 16, 1996 PCT Filed Dec. 13, 1995 PCT Pub. No. WO96/22208 PCT Pub. Date Jul. 25, 1996A boosted braking device for a motor vehicle having a master cylinder (200) and a pneumatic booster (100). The pneumatic booster (100) is capable of being operated by an operating rod (28) controlling the opening of a valve (26) in order to actuate a main hydraulic piston (34) in the master cylinder (200). The booster (100) has a rigid casing (10) divided in a leaktight fashion into first (12) and second (14) chambers by a moving partition (16) capable of driving a pneumatic piston (22) which can move relative to the casing (10). The main hydraulic piston (34) includes a hollow moving cylinder (38) having a secondary piston (40) which slides in a leaktight fashion in the interior thereof. The moving partition (16) is held fast to the moving cylinder (38) and is slidingly mounted on the pneumatic piston (22) so as to slide relative to the moving cylinder (38) in a forward direction over an axial distance (L) from an initial position of abutment against the rear of the pneumatic piston to a final position in which the moving cylinder (38) abuts the secondary piston (40). An annular piston (70) is held fast to the main hydraulic piston (34) when the travel of the annular piston (70) in bore (62,64) is less than the axial distance (L) while the annular piston (70) is capable of sliding over the main hydraulic piston (34) when the travel of the annular piston (70) in the bore (62,64) is greater than the axial distance (L) to obtain the maximum development of braking forces.
