Abstract
A brake unit having a brake line extending between a master brake cylinder and a wheel brake. A changeover valve is included in the brake line on the master brake side and a valve arrangement for the brake pressure modulation is on the wheel brake side. A return line extends from the valve arrangement to a high-pressure pump for feeding a pressure medium into the brake line. Connected to the return line is a storage chamber for the pressure medium taken from the wheel brake. A suction line starts from the brake line on the master brake cylinder side, with a hydraulically switchable check valve connected to the return line. A non-return valve is arranged between the connection of the suction line and the storage chamber. The high-pressure pump can draw pressure media from the master brake cylinder. The entry of the pressure media into the storage chamber from the suction line is prevented by the non-return valve. The hydraulic brake unit is suitable for motor vehicles.
