An anti-lock hydraulic brake system comprising a master cylinder and a wheel brake, with a flow control valve being inserted into the brake line. A non-return valve is inserted into the brake line. A direct connection is established between the wheel brake and the master cylinder, with a non-return valve opening towards the master cylinder. A pump supplies fluid into the brake line between the non-return valve and the flow control valve. A high-pressure accumulator is provided on the pressure side of the pump.

An anti-lock hydraulic brake system, comprising: a master cylinder; a wheel brake; a flow control valve directly fluidly connected to the wheel brake, said flow control valve having an inlet chamber and an outlet chamber and having a piston operably connecting the inlet chamber with the wheel brake

An anti-lock hydraulic brake system, comprising: a master cylinder; a wheel brake; a flow control valve directly fluidly connected to the wheel brake, said flow control valve having an inlet chamber and an outlet chamber and having a piston operably connecting the inlet chamber with the wheel brake in a first piston position and operably connecting the output chamber with said wheel brake in a second piston position; a first brake line connecting said master cylinder to the inlet chamber of said flow control valve; a first non return valve disposed in said first brake line and adapted to close toward said master cylinder; a low pressure accumulator; a pump having a suction side connected to said low pressure accumulator and a pressure side; a first return line defined between said suction side of said pump and the outlet chamber of said flow control valve and including said low pressure accumulator; a proportional pressure limiting valve being electrically operated disposed in said first return line between said flow control valve and said low pressure accumulator wherein the wheel brake pressure is operably regulated to a pressure proportional to an electrical current through the proportional pressure limiting valve, said proportional pressure limiting valve being exclusive of other electrically operated valves with respect to the wheel brake; a pressure line connected between said pressure side of said pump and a portion of said first brake line between said first non return valve and said flow control valve; a high pressure accumulator connected to said pressure line, said high pressure accumulator having a shut off valve; a direct line connected between said high pressure accumulator and a portion of said first brake line between said first non return valve and said master cylinder with flow therethrough controlled by the shut-off valve; and a second non return valve disposed in a second return line directly connecting said wheel brake and the portion of said first brake line between said first non return valve and said master cylinder, said second non return valve adapted to open toward said first brake line.
