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. 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.
