    • A pneumatic brake booster having a casing (10) with an axis of symmetry (X-X') divided in a leaktight fashion by a movable wall structure (12) into a front chamber (14) permanently connected to a source of low pressure, and a rear chamber (16). The rear chamber (16) is connected selectively to the front chamber (14) or a source of high pressure by a three-way valve means (36). The three-way valve means (36) is actuated by a control rod (30) capable of pressing, via a front face of a plunger (28), on a rear face of a push rod (56) secured to a reaction disc (58) when a plunger (28) slides in a bore (26) of the movable wall (12). The three-way valve (36) includes a valve element (36) located in a tubular rear part (22) of the movable wall (12) and interacts via of an annular front face (40) with a first annular valve seat (28a) formed on the plunger (28) and with a second annular valve seat (20a) formed on the movable wall (12). The first valve seat (28a) is concentric with the second valve seat (20a) and a smaller diameter. The annular front face (40) of the valve element (36) is able to move in the tubular rear part (22) of the movable wall (12) and sealed therein by outer and inner edges. The annular front face (40) of the valve (36) has a least one opening (46) causing a chamber (44) to be situated behind the annular front face (40) of valve (36) to communicate with a space (35) situated between the first valve seat (28a) and the second valve seat (20a). The resultant of forces generated by the low pressure and high pressure exerted on the plunger (28) is permanently and essentially negligible.

    • A pneumatic brake-booster having a casing with a piston located therein consisting of a hub and a skirt to define a front chamber and a rear chamber. The front chamber is connected permanently to a vacuum source and the rear chamber is connected selectively through a bore in the hub to one of the front chamber and atmosphere by a control valve. The control valve is actuated by a control rod capable of pressing through a front face of a plunger on a back face of a reaction disk fastened securely to a thrust rod. A return spring for the control rod is located between the piston and the plunger. The control valve includes a shutter valve which interacts with a first circular valve seat formed on the plunger and a second circular valve seat formed on the piston. The shutter valve is characterized by a flexible membrane having a first bead fixed in a leaktight manner to a peripheral edge of the hub and a second bead connected in a leaktight manner to an internal peripheral edge of a rigid tubular component. The rigid tubular component is slidably located in a leaktight manner in the bore of the hub and moves to engage the first and second valve seat to control the communication of atmosphere to the rear chamber.

    • 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).
