    • 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 (10) with a piston located therein. The piston has a hub (22,22') with a tubular part (24,24'), a portion of which extends in a sealed fashion through the casing (10). The hub (22,22') has an annular groove (29) which receives an internal peripherial bead (19) of a rolling seal (18) which holds a skirt (16) against a shoulder. The rolling seal (18) engages the casing (10) to define a front chamber (12) which is permanently connected to a source of depression and a back chamber (14) selectively connected to the front chamber (12) and to atmosphere via valve apparatus (22a,32a,36). The valve apparatus (22a,32a,36) is actuated by a control rod (34) capable of pressing, by way of a front face on a plunger (32), on a first face of reaction disk (40) secured to a second face on a push rod (42). The tubular part (24') of the piston is connected to the hub (22) by clipping.

    • 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.
