    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.

    Abstract: An automatically controlled braking system comprising a pneumatic vacuum servo and a pneumatic solenoid valve capable of selectively connecting the serov to first or second sources of pressure. The solenoid valve includes a flap valve which is subjected to a suction force proportional to the difference between the first and second source of pressured and acts in the same direction as an electromagnetic actuating force. Elastic means act on and apply a greater force to the flap valve to oppose the suction force. A current generator supplies a current having a predetermined maximum intensity to the solenoid to develop an actuation force overcome the elastic force and effect actuation of the vacuum servo.

    Abstract: A brake device having a pneumatic brake booster and a master cylinder. The master cylinder operates in response to a combined actuation force derived from a boost force and an input force. The input force is applied to a control rod for opening a valve to develop a pressure differential across a partition. The pressure differential acts on the partition to develop the boost force which is transmitted through a first hydraulic piston retained in the master cylinder. A movable pneumatic piston which carries the control rod is connected to the hydraulic piston and after an initial travel during which the valve is opened acts directly on the hydraulic piston to provide a portion of said actuation force. The input of the pneumatic piston to the hydraulic piston provides a way to operate a master cylinder in response to an input force in the event of a failure of a hydraulic circuit connected to the master cylinder.

    Abstract: The invention covers a brake-booster of the partial vacuum type comprising a direct braking control mechanism (hill-holder or traction control). In order to implement these functions, the piston (20, 22) of the booster is "double" through a partition (52) which is attached securely to the piston and defines with the piston a third chamber (50). This chamber is connected by a flexible pipe (66) and a double valve (72) either to partial vacuum (78) or to atmospheric pressure (76).
