Abstract
The circuit comprises a primary circuit (2) feeding brake motors (5) and (7) and a secondary circuit (3) feeding a brake motor (9). In normal operation a valve (11) isolates the brake motor (22) from the secondary circuit (3). The pressure in the primary circuit then controls the pressure prevailing in the brake motor (22) with the aid of a pressure balancing device (25) installed between the feed lines of the brake motors (7 and 22). In the event of the failure of the primary circuit (2) the valve (11) establishes communication between the brake motor (22) and the secondary circuit (3) to effect the braking of the wheel associated with the brake motor despite the fact that the balancing device (25) is put out of action in this situation. Application to a brake circuit equipped with an anti-wheel-lock device.
