Abstract: The present invention relates to a pedal command device with variable reduction for a master-cylinder type pressure emitter. The device includes a pedal articulated on a lever that is pivotally movable about a shaft and recalled by a spring. The pedal includes at one of its ends a cam that actuates a pusher articulated on the lever, which pusher commands a pressure emitter such as a vehicle brake master cylinder by means of a thrust member and a rod.

Abstract: A braking pressure limiter device in which an inertia responsive valve normally closes under deceleration of the vehicle but has its closing action impeded by a linkage connected to an anti-roll bar so as to be responsive to the loading of the vehicle, for example the vehicle suspension to sense loading of the rear axle.

Abstract: This invention relates to automobile braking systems of the kind that employ a device for limiting braking pressure and intended particularly for systems which have separate supply circuits for the front and rear-wheel brakes. Such limiting devices conventionally comprise a limiter body which has an inlet orifice and an outlet orifice with a valve mounted therein for cutting off the inlet orifice from the outlet orifice, a movable piston subject to the hydraulic pressure at the inlet orifice, an inertial mass which is capable of movement with respect to the body, load-sensitive means and elastic means for co-operation with the inertial mass and the piston.
