<p>An hydraulic braking system of the brake-by-wire type has an hydraulic pressure source comprising an hydraulic accumulator (32) adapted to be charged by a pump (30). An accumulator isolating valve (34) is so positioned and biased to correspond to the direction of flow from the accumulator to a solenoid-operated proportional valve (12). The valve (34) is biased into a closed position in opposition to the flow from the pump to the accumulator.</p> |
