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.

Device for limiting brake pressure according to vehicle load and

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. In accordance with the present invention, the load sensitive means co-operate via a group of elastic members with the inertial mass and with the piston in the direction in which the valve opens: moreover, the force of the pressure at the inlet orifice is exerted against a working face of the movable piston in opposition to the contrary force exerted by a load, and the valve itself is arranged to be closed as a result of the effect of hydraulic pressure and inertial force.
