A pressure-medium brake system with division into two or more brake circuits is proposed. A relay valve is incorporated into each brake circuit. Control medium and working medium of each relay valve are supplied by the same pressure-medium source. For each brake circuit a single valve is provided in a service brake valve, which additionally has an electrical supply, with which the actuation of all relay valves can be controlled. The pressure-medium brake system is perferably embodied as an air-brake system and is intended for utility vehicles, such as trucks and buses. |
