Summary:PCT No. PCT/FR99/00266 Sec. 371 Date Feb. 26, 1999 Sec. 102(e) Date Feb. 26, 1999 PCT Filed Feb. 8, 1999 PCT Pub. No. WO99/41124 PCT Pub. Date Aug. 19, 1999The invention relates to a pneumatic booster using, by way of reaction members, a number of balls (15) trapped between three bearing faces (12, 13, 14), the first bearing face (12) consisting of a projecting and at least partially conical surface of the booster plunger (9). According to the invention, the first bearing face (12) has at least two different slopes (P1, P2) to allow a decrease in the reaction force in the event of quick actuation of the booster.
