    • A brake actuation apparatus includes a pneumatic booster and a master cylinder. A control rod in the booster responds to an input force for actuating a valve in the brake booster to develop an actuation force which is applied to a main hydraulic piston located in the master cylinder to pressurize fluid and effect a brake application. The main hydraulic piston includes a cylinder member with a bore therein for retaining a secondary hydraulic piston connected to the control rod. The cylinder member has at least one opening whereby pressurized fluid is communicated between the master cylinder and bore as function of a flow-rate reducer located in the one opening. The communication of fluid between the master cylinder and bore is always from the higher fluid pressure toward the lower fluid pressure. The fluid pressure in the bore acts on the secondary hydraulic piston to oppose the input force and thereby modify the time the valve remains opened by the input force and correspondingly the development of the actuation force for the pressurizing of fluid in the master cylinder.

    • The present invention relates to an assembly comrising a bulkhead (10) separating an engine compartment from a passenger compartment of a vehicle and a pneumatic booster (12) assisting the braking of the vehicle and comprising essentially a tube into which an operating rod (16) actuated by a brake pedal situated in the passenger compartment penetrates and a closed casing defining the pneumatic chambers of the booster disposed in the engine compartment. According to the invention the tube (14) is fastened to a collar (18) which has a diameter substantially smaller than that of the opening; the collar (18) is shaped in such a way as to have, at least in part, an end wall (20) parallel to the bulkhead; the collar (18) has a peripheral groove housing a ring (22); the ring (22) has, at least in part, an elastic edge (24) projecting outwards. Thus, when the booster is in position in the opening, the end wall (20) of the collar abuts against that face of the bulkhead (10) which is situated in the engine compartment and the elastic edge (24) of the ring forms a spacer between the other face of the bulkhead (10) and the groove.

    • A pneumatic servo for assisting braking. The servo has a casing with an axis of symmetry which is divided in leaktight fashion by a movable wall structure into a front chamber and a rear chamber. The front chamber is permanently connected to a source of partial vacuum while the rear chamber is connected selectively to the front chamber and to air in the surrounding environment by a three-way valve. A sleeve divided an annular bore located in a projection that extends through the movable wall through the casing into a static volume and a concentric annular volume. The sleeve engages the projection to position the three-way valve in the bore. A return spring located in the static volume engages the control rod while an end plug engages the sleeve to seal the static volume from the surrounding environment. The annular volume being is respectively connected by first and second openings to the surrounding environment and bore. In response to an input from the control rod, air flows from the environment past the three-way valve to the rear chamber. Fins located in the annular volume engage air in the annular volume creating a circular flow path for the air on moving from the first opening toward the second opening so as to reduce any abrupt change in direction of the moving air on being presented to the three-way valve that may create noise.

    • An 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).

    • A pneumatic brake booster having a piston which slides in a casing with a portion that extends outside of the casing. A tubular protective bellows has a first end connected to the casing and a second end that engages an input rod through which an operational signal is communicated to a valve retained the valve.
