Abstract
A pressure medium brake system for motor vehicles is proposed in which a high-pressure-producing apparatus and a normal-pressure brake apparatus are provided. The brake pressure is reduced with the aid of pressure limiters from high pressure to normal pressure. In order to attain rapid filling of the brake cylinders, one relay valve is disposed before each group of brake cylinders, the relay valves being triggered with normal pressure and very rapidly directing the high pressure into the brake cylinders with a large pressure drop. Upon attaining the maximum pressure level of the normal pressure, the supply of high pressure in the relay valve is cut off. The pressure medium brake system is preferably used as a compressed-air brake system for trucks and trailer-trucks.
