Abstract

The equipment controls distribution of liquids by spray vehicles application over a large and variable area being made at a constant rate per unit of area. The vehicle has a platform with spray nozzles. The control comprises two double-acting rams the movement of whose piston rods simultaneously determines the number of nozzles in use and the output of the hydraulic pump coupled to the liquid feed pump in proportion to this number. The rams are controlled from the vehicle or remotely.
