Abstract: A method of detecting the braking of a vehicle comprising a push rod (200) intended to transmit an amplified braking command to a master cylinder. A plunger (220), arranged parallel to the primary piston (200) so as to reproduce the movements of this piston, and a sensor (230) which senses the movements of the plunger (220), this sensor (230) being fastened to the booster (250), are used to detect a braking operation by detecting a movement of the plunger (220).

Abstract: Our problem relates to a master cylinder with a U-shaped seal. Our goal is to avoid defective bleeding of hydraulic braking systems. The defects arise out of the fact that the vacuum causes the lips of the seal (21) to stick together and to stick against the wall (41). To achieve this, reliefs (42) will be created on one wall (44) of one lip (28) facing the other lip (27) and on the edge face (50) of this same lip. These reliefs will prevent the lips from sticking tightly to one another and to the wall facing the edge face of the lips. This lack of sticking will prevent a vacuum from being created between the two lips and between the edge face of the lips and the wall (41). As a result, the seal will be able to return to a position in which bleeding can be performed effectively.

Abstract: Braking device including a master cylinder (2), a primary piston (3), a control member (4), a booster (6) coupled to the control member (4), and an assist valve (VA) defined by a reaction piston (17) with a bore (18) therein for receiving a ratio control member (24). The control member (24) has a piston (29) with a head (25) located in a chamber (26) between the reaction piston (17) and a bushing (27) retained in the bore (18). The bushing (27) has an axial passage (28) that receives a head (25) of piston (29) to form a valve (36) for closing an inlet to a passage (30) in the piston (29). The bushing (27) slides within bore (18) to limit a pressure difference between the chamber (26) and a front part (18a) of the bore (18) to a value below a pressure difference that causes the valve (36) to open.

Abstract: A pneumatic brake booster for a motor vehicle, of the type in which the movements of a control rod (38) are able to determine the openings and closings of at least one axial intake valve (52) which is inserted between a pressure source subjected to the pressure (Pa) higher than the first pressure (P1) and a rear chamber (18) of the booster, and of at least one axial equalizing valve (50) which is inserted between a front chamber (16) and the rear chamber (18), to actuate a moving partition (14) inserted between the front chamber (16) and the rear chamber (18), characterized in that it comprises a tubular element (76) of which axially offset transverse faces (78, 80) comprise first elements (82, 84) for sealing the axial intake and equalizing valves (50, 52) and that the control rod (38) is able to operate via two concentric springs (40, 122) having different stiffnesses.

Abstract: In order to connect a pneumatic booster (S) to a brake pedal (F), it is necessary to fix a control rod (1) of the booster (S) to the brake pedal (F). This fixing is made difficult because of the location of the booster which is located in the engine compartment and because of the location of the brake pedal (F) which is located in the cabin of a vehicle. In order to make it easier to fix the booster (S) to the brake pedal (F), a method for the rigid and blind fixing of the brake pedal (F) to the control rod (1) of the booster is provided. This result is obtained by nesting two nesting portions (2, 3) of a control rod (1) which are connected respectively to the booster and to the brake pedal. The two portions are held one inside the other using a spring clip (25) housed in a circular groove (26). This elastic attachment device also allows play to be taken up and allows the mounting to be stabilized.
