Abstract
A sealed, double valve assembly mounted on a vehicle body is connected to a source of pressurized air and controls the air pressure delivered to two auxiliary systems connected to it. The first auxiliary system is a brake force regulator and the second auxiliary system is a headlight beam adjustment mechanism which uses a pneumatic servo-member. Control rods connected to the axle change the degree of compression of a control spring in the double valve assembly, thereby opening or closing valves which admit or release compressed air so as to change the operating pressure of the associated auxiliary systems.
