ABSTRACT:
A fluid pressure braking system for an articulated vehicle includes a pair of manually operated, push-pull control valves and a pressure differential responsive dual supply valve. The inlet of one of the manually operated valves is connected to the fluid pressure source, and the outlet is connected to the parking brakes on the power portion of the articulated vehicle and also to one inlet of the dual supply valve. Another inlet of the dual supply valve is connected directly to the fluid pressure source. The outlet of the dual supply valve is connected to the inlet of the second manually operated control valve, the outlet of which is connected to the parking brakes on the towed or nonpowered portion of the articulated vehicle. Application of the spring brakes on both portions of the vehicle is effected by actuation of one of the valves, but release of the spring brakes on both portions of the vehicle requires actuation of both of the manually operated valves.
