ABSTRACT:
An anti-lock controlled/traction-slip controlled brake system operating according to the return delivery principle. A charging circuit is provided for charging an accumulator (20). In order to charge the accumulator, valves (21, 22 and 15) are switched over, thereby establishing a pressure fluid connection between the master brake cylinder as well as the regulating valves (11, 15) by way of the pump (14) to the accumulator (20). The pump delivers fluid out of the supply reservoir (4) connected with the master brake cylinder into the accumulator (20). Since the connection between the master brake cylinder (1) and the wheel brakes remains open when the accumulator is charged, a braking operation is immediately possible even during the charging operation.
