Hydraulic braking circuit fitted with a wheel-antilock device for a motor vehicle

A hydraulic braking circuit including a master brake cylinder controlled by a brake pedal and with a wheel-antilock device, for a motor vehicle, the device comprising a pressure generator, which is started up at the beginning of an antilock-braking sequence, for selectively supplying at least one wheel brake, a member for automatically isolating the wheel brake from the master brake cylinder when the pressure generator is activated, a member bringing the wheel brake into communication with means for storing hydraulic fluid, means for limiting the pressure of the hydraulic fluid provided by the pressure generator to a value equal to a jamming pressure increased by a predetermined pressure, and a pressure-memorization device connected to the wheel brake, the limiting means comprising a slide distributor having a movable slide which can move between first and second pressure chambers which are connected to the pressure generator and to the pressure-memorization device, respectively, so that the movable slide is displaced between first and second positions under the influence of a differential pressure established between the first and second pressure chambers in order to establish communication between the pressure generator and the means for storing hydraulic fluid.
