ABSTRACT:
A load-sensing valve for an air pressure braking system comprises a diaphragm responsive to a signal pressure, as from a brake valve, and actuating through a rockable beam a two stage valve for controlling flow of pressure air to the brakes, the beam fulcrum being displaceable in accordance with vehicle load, and a further diaphragm having operable connection with the two-stage valve and responsive to delivery pressure, the two-stage valve consisting of a pilot valve operable alone where air usage is small to provide high sensitivity and a main inlet valve which is brought into operation with increased inlet pressure and larger air flow.
