Abstract
A hydraulic brake system for automotive vehicles comprising a brake master cylinder (1) connected to an unpressurized reservoir (12) and a brake line communicating with a working chamber (4, 5) of the brake master cylinder (1) and leading to pressure control valves (17, 18) of a brake slip control apparatus (19), connected downstream of which valves is at least one wheel brake. The working chamber (4, 5) of the brake master cylinder (1) on activation of the brake slip control apparatus (19), is connectable to a pressure-fluid source (30) by way of a throttling non-return valve (15, 16) closable in the direction of the wheel brake. The pressure of the fluid source is controlled to correspond to at least the pressure in the working chamber (4, 5) of the brake master cylinder (1). Thus, the brake system requires little structural and monitoring efforts and affords an energy supply for the brake slip control apparatus which is independent of the actuating system of the brake master cylinder.
