ABSTRACT:
A dual-circuit pressure medium brake system is equipped with relay valves disposed ahead of the brake cylinders. Each brake circuit is equipped with a control also acting in the other circuit and overlapping each other, and a primary brake circuit is designed in such a way that it contains all control elements necessary for optimal brake pressure adaptation, while a secondary brake circuit is merely an auxiliary brake circuit without control elements. In this manner each brake pressure metering can be simultaneously adjusted. During the loss of the primary brake circuit, the secondary brake circuit guarantees a minimal brake pressure. Such a pressure medium brake system is preferably used in air brake systems of motor vehicles.
