摘要： Power braking device comprising a pneumatic brake servo (1) associated with a master cylinder (2). The servo comprises a movable pneumatic piston (5) carrying a valve (7) and operates on a hydraulic reaction principle, the hydraulic piston (11) of the master cylinder comprising a hollow mobile cylinder (13) receiving an input force. The hydraulic reaction generated by the boosting force is delayed by means of a non-return valve (22) located between the master cylinder (2) and the movable cylinder (13).

摘要： Silent pneumatic brake servo comprising a shell (10) with an axis of symmetry (X-X') sealingly divided by a movable wall structure (12, 20) into a front chamber (14) permanently linked to a vacuum source, and a rear chamber (16) selectively linked to the front chamber (14) or the outer air by a three-way valve (36) actuated by a plunger (28) sliding in a bore (26) of the movable wall (12, 20) and secured to an axial control rod (30) acted on by a return spring (68) housed in an annular space (32) between the control rod (30) and a rear tubular part (22) of the movable wall structure (12, 20) projecting outside of the shell (10), the three-way valve (36) being arranged in said rear tubular part (22) and including a valve element (36) cooperating through a first annular surface (A) with a first valve seat (28a) formed on the plunger (28) and through a second annular surface (B) with a second valve seat (20a) formed on the movable wall (20). According to the invention, the first (A) and second (B) annular surfaces are located in different annular planes, the first (A) and second (B) annular surfaces being linked by a surface (C) with a generally truncated shape for guiding moving air downstream of the first valve seat (28a) when it is remote from the first annular surface (A).

摘要： Power braking system comprising a pneumatic servo (19) associated with a master cylinder (2), the servo operating on a hydraulic reaction principle. Said servo comprises a movable pneumatic piston (5) carrying a control valve (7) actuated by a rod (8), and a partition (4) movable under the effect of a pressure difference and generating boosting power. The movable partition (4) is slidingly mounted in relation to the pneumatic piston (5) to act at an early stage on the master cylinder. The device of the invention provides enhanced braking power for a short control rod stroke.

摘要： Pneumatic brake servo comprising a casing (10) housing a piston which includes a hub (22, 22') having a rearward extension in the form of a tubular part (24, 24') sealingly passing through the casing (10) and supporting a skirt (16). The hub comprises an annular groove (29) which receives the inner peripheral bead of a rolling diaphragm (18) defining a front chamber (12) continuously linked to a vacuum source and a rear chamber (14) selectively connected to the front chamber (12) or to the atmosphere by a valve means (22a, 32a, 36). Said valve means is actuated by a rod (34) capable of engaging, through the front face of a plunger (32), the first face of a reaction disk (40) integral with the second face of a thrust rod (42). According to the invention, the rear tubular part (24') of the piston is snap-locked onto the hub (22').
