DUAL AIR BRAKE SYSTEM

The Westinghouse Brake and Signal Company, Ltd. has developed a simple dual brake system, which is claimed to represent an advancement in modern vehicle braking technique. The provision of independence peneumatic storage and control for front and rear brake systems ensures that, in the event of any part of one system being rendered inoperative, braking is obtained from the unaffected system. A typical layout is shown in which a common air compressor, controlled by a single unloader and safety valve, supplies air to two main reservoirs; each of these provides independent, air storage for one part of the dual system, and is isolated from the other by inclusion of check valves in the supply from the compressor. The supply and release of air from the reservoirs to the piston type brake cylinders' or diaphragm brake chambers is by means of a lightweight dual control valve.
