Abstract
A power-assisted hydraulic braking system includes a main brake line into which a setpoint brake pressure can be introduced via a brake valve actuated by a brake pedal, and from which a plurality of wheel brake lines branch off, each leading to an actuating unit of a wheel brake, and a valve arrangement of an ABS controller, comprising an inlet valve disposed between the main brake line and one of the wheel brake lines and an outlet valve disposed between the relevant wheel brake line and a pressureless return line. The inlet valve and the outlet valve are embodied as pressure-controlled 2/2-way switching valves with suitably sized switching cross-sections. At least one pilot control valve is associated with each of the inlet valve and the outlet valve, via which a control connection can be alternately subjected to a low or high control pressure to change over.
