Patent ID: 7429087

Claim:
A pneumatic system for supplying compressed air to an agro-industrial vehicle and/or agro-industrial machinery, the system comprising: an air compressor, at least one filter connected to said air compressor, wherein the air compressor takes air from the atmosphere through the filter; a governor valve connected to the air compressor, wherein the governor valve controls air pressure through the system; an air decanter connected between the compressor and the governor valve; a dual circuit foot valve connected to the air compressor, the dual circuit foot valve having a) a first chamber, b) a second chamber, c) a first main outlet and a second main outlet, and d) a two-way device to connect the agro-industrial vehicle with a hose on the agro-industrial machinery; each chamber having an air inlet and an air outlet, wherein the air outlet of each chamber is connected to a pressure measurement device; at least two air storage tanks connected to said dual circuit foot valve, wherein one of the storage tanks is connected to the air inlet on each chamber; wherein the first main outlet is connected to a rear circuit having a first air chamber and the second main outlet is connected to a front circuit having a second air chamber, wherein the dual circuit foot valve sends air pressure to the rear circuit and the front circuit independently; wherein the operation of the dual circuit valve establishes an air pressure link from the storage tanks to the first air chamber, as well as to the second air chamber, wherein the movement of the dual circuit foot valve activates a vehicle's air brake device, wherein the agro-industrial machinery is chosen from harvesters, crop-sprayers, sewers, hoppers, grain augers, wagons, carts, towing vehicles, or combination thereof; wherein the system is adapted to work in parallel with a brake system of the agro-industrial vehicle and at the same time provide pneumatic pressure to the agro-industrial machinery.
