  • Publication number: 20040035287
    Abstract: A servomotor for an assisted braking of a motor vehicle comprises a rear wall (20) in which an axial cylindrical shaft (48) is formed, an intermediate part of which exhibits an inner shoulder (56) limiting the axial rearward motion of the piston (28) and capable of resisting a pulling force exerted on the control rod (12) driven by the brake pedal.

  • Patent number: 5597012
    Abstract: A valve assembly having a body with a bore. The housing has an inlet for communicating pressurized fluid to the bore and an outlet for delivery of the fluid to a system. A piston located in the bore carries a valve element connected to a push rod. The push rod is mounted in the body and can retract into the body and open the valve element in a rest position of the valve to eliminate any shift between the inlet and outlet pressure when the pressure of the fluid is below a predetermined value.

  • Patent number: 5487452
    Abstract: The ball and revolving plate (1) clamping device uses guide cavities each comprising a housing (7a) which determines a single position for the ball (3), and a ramp (7b) which is connected to the housing (7a) by way of a plurality of points of intersection (7c) situated on a slope discontinuity. This arrangement enables the clamping force to be optimized.

  • Patent number: 5272958
    Abstract: The invention relates to a vacuum-operated servo-brake comprising, in a casing consisting of a shell (10) and a cover (12), a piston (20) separating leaktightly two inner chambers (22, 24), a valve means controlled by a rod (32) projecting from the casing in order to ensure the operation of the servo-brake, and a prestressed spring (34) for returning the piston (20) to its rest position substantially abutting the cover (12), the spring (34) bearing on the shell (10). According to the invention, the spring (34) comprises a mechanism enabling its extension to be limited when the shell (10) and the cover (12) are not fixed to each other.

  • Patent number: 5226694
    Abstract: A hydraulically controlled brake system for a motor vehicle, comprising a master cylinder, a corrector intended for reducing the pressure prevailing in the rear-wheel brakes in relation to that prevailing in the front wheels, and a wheel anti-lock device. The corrector is of the type with a controlled shift of the cut-off point. During the operation of the anti-lock device, the cut-off point has a specific value higher than that of a corrector equipping the vehicle without a wheel anti-lock device, while it is substantially equal to the latter in the event of a failure of the device.

  • Patent number: 5205621
    Abstract: A pressure reduction mechanism (10) is installed in a brake circuit of the rear axle of a motor vehicle, comprising a master cylinder (1) and at least one monitoring device, the mechanism executing the brake-pressure reduction only in specific circumstances and comprising a regulating piston (14) sliding sealingly in a bore (13) and stressed by at least one spring (16, 17) in the opening direction of a regulating valve (15). The spring (16, 17) is arranged in a sealed chamber filled with an incompressible fluid, and a solenoid valve (22) controls the opening or closing of communication between the chamber and a reservoir of the fluid under low pressure.

  • Patent number: 5201179
    Abstract: The invention relates to a brake subassembly for a vehicle having an engine compartment and a passenger cell separated by a bulkhead (46), the subassembly comprising: a pneumatic boost servomotor controlled by way of a pedal (28) and intended to be fixed to the bulkhead (46), the servomotor comprising, coaxially, a front shell (14), having a cylindrical wall, and a rear cover (16) and having, on the inside, two chambers (18, 20) separated in leaktight fashion by a piston (22) provided with a diaphragm (26) ensuring leaktightness between the two chambers, a master cylinder (10) fixed to the front shell (14) and at least one brake pedal (28).

  • Patent number: 5168966
    Abstract: A brake assembly with hydraulic boosting, comprises at least one disk brake having a fixed part (1), a caliper (3), a brake motor (82) actuated by a fluid under pressure, a master cylinder (48) and a device (15) for recovering the energy dissipated during braking. The device (15) comprises at least one energy-recovering cylinder (21) with its piston (19) which is associated with the fixed part (1) and with the caliper (3) and the working chamber of which is connected fluidly to the brake motor (82). A hydraulic booster/limiter is connected between the energy-recovering cylinder (15) and the brake motor (82), the hydraulic booster/limiter being controlled by the pressure of the fluid generated in the master cylinder (48).

  • Patent number: 5154492
    Abstract: The load sensing brake proportioning valve of a vehicle comprises a first piston (14) sliding in a stepped bore made in a body, and carrying a normally open shutter (18) arranged between a source of fluid under pressure and the associated brake circuit, the first piston (14) being moveable counter to a spring (16) under the effect of the pressure of the fluid which tends to close the shutter (18), a sliding rod (24) normally bearing between a pusher (20), the position of which is a function of the load of the vehicle, and the shutter (18). The proportioning valve comprises a locking mechanism immobilizing the sliding rod (24) as soon as the pressure of the fluid in the associated brake circuit exceeds a specific threshold.

  • Patent number: 4637747
    Abstract: Device for mounting a protective cap (18) on a support (12), the support (12) having a base surface (20) intended to be at least partially protected by the cap (18), and a first bearing surface (28, 38, 54), the device incorporating a first rigid component (22, 32, 44), joined to the periphery of the cap (18), and a locking component (26, 40) situated between the first rigid component and the first bearing surface, characterized in that the locking component (26, 40) is inserted by sliding laterally between the first component (22, 32, 44) and the first bearing surface (28, 38, 54) so as to fix the cap (18) in position bearing against the base surface (20) of the support.
