Abstract
The correcting valve comprises two identical parallel pistons which control the opening or closing of two valves which are disposed between two inputs and two outputs of two braking circuits. Two thrust members which are subjected to a control pressure urge the pistons in the direction for opening the valves. Two reaction springs co-operate with two transmission members for urging the thrust members in the opposite direction. When the two brakes circuits are supplied, the correcting valve has an identical cut-off pressure for the two circuits. In the event of failure of one of the circuits, the transmission members come into mutual engagement, resulting in a doubling in the cut-off pressure in the circuit which is still intact. The invention is used for dual-circuit braking systems for motor vehicles.
