Summary: | PCT No. PCT/FR95/00537 Sec. 371 Date May 4, 1995 Sec. 102(e) Date May 4, 1995 PCT Filed Apr. 25, 1995 PCT Pub. No. WO96/00669 PCT Pub. Date Jan. 11, 1996An assembly of a pneumatic brake booster (100) and a master cylinder (200) for a motor vehicle. The pneumatic brake booster (100) has a casing (20) fixed to the bulkhead (10) of the vehicle. The casing is divided in leaktight fashion by a movable wall structure (22) into a front chamber (24) permanently connected to a source of partial vacuum and a rear chamber (26) connected selectively to the front chamber (24) or to the atmosphere by a valve means (16). The valve means (16) is actuated by a control rod (14) for actuating a push rod (28). The master cylinder (200) has a body (21) formed with at least first and second flanges (38, 38'; 40, 40'). The first and second flanges (38, 38'; 40, 40') interact with corresponding screws and nuts to fix the body (21) with the casing (20) of the booster (100). The body (21) has a bore (34) for slidingly receiving at least one piston (32) which is actuated by the push rod (28) of the brake booster (200). Linkage (60, 60') is provided so that a rotation of the master cylinder (200) with respect to the booster (100) in response to a rotational torque applied to the master cylinder (200) as a result of being pushed substantially breaks the mechanical link between the piston (32) of the master cylinder (200) and the push rod (28) of the booster (100). |
