Dispensing device for agricultural sprayer

A distribution device for an agricultural sprayer connected to a plurality of product sources and including a plurality of spraying members, the distribution device comprising:

• a supply manifold having at least two inlets and at least one outlet, each inlet adapted to be linked to one of said product sources and each inlet cooperating with a closing valve;
• a distribution manifold having at least one inlet and at least two outlets, each outlet adapted to be linked to one of said spraying members and each outlet cooperating with a closing valve;
• a distribution conduit linking the at least one outlet of the supply manifold to the at least one inlet of the distribution manifold;
• a control mechanism including at least one camshaft carrying a plurality of cams associated with the closing valves of the inlets of the supply manifold and the closing valves of the outlets of the distribution manifold, each cam acting on opening and closing of a corresponding one of said closing valves of the supply manifold and the distribution manifold, the at least one camshaft being rotatably mounted between several angular positions such that the closing valves of the outlets of the distribution manifold and the closing valves of the inlets of the supply valves are actuated simultaneously by the at least one camshaft to allow supply of one of said spraying members by at least one of said product sources;
• and
• an actuating device for actuating the camshaft.
