A hydraulic unit for wheel slip control, which is located between a master cylinder and wheel brake cylinders. Reflection damping devices are installed in main brake lines located between the hydraulic unit and the master cylinder which damp pressure waves that originate at control valves of the hydraulic unit. When the control valves are triggered in the wheel slip control mode the pressure waves are largely kept away from the master cylinder. By the means of length adaptation of the main brake lines, the brake lines can also contribute to the damping.

A hydraulic brake system for a vehicle, having a master brake cylinder, at least one wheel brake, a hydraulic unit that for wheel slip control includes at least one pump and at least one control valve, at least one damping device connected in the hydraulic vehicle brake system for damping pressure waves rising in the hydraulic pressure fluid in the vehicle brake system, at least one main brake line between the master cylinder and the hydraulic unit, and at least one wheel brake line between the hydraulic unit and the at least one wheel brake, the at least one damping device is embodied as a reflection damping device (17, 18, 19, 20; 17a, 17b) and is installed between the master cylinder (3) and the at least one wheel brake (6, 7, 8, 9), said reflection device (17a, 17b, 17c) has an outer damper line (50, 50a, 50b) with a length of substantially 500 mm and with an inside diameter that is larger than the inside diameter of the brake line (11, 12, 13, 14), and a substantially coaxially disposed inner damper line (51, 51a, 51b) with a length of substantially 400 mm and a diameter that substantially matches the diameter of the brake line, and, a reflector (52) installed in a pressure-tight fashion between ends (60, 61) of the inner damper line (51), in such a manner that two chambers (53, 54) are formed, one on each end of the reflector (52, 70, 71, 86 ) between the outer damper line (50) and the inner damper line (51).
