An injection spraying system for mixing additives in controlled amounts to water
for spraying, which improves handling and calibrating of the concentration of the
mixture. The system includes a water tank, mixing globe, pump device, unloader
chamber and a worm reduction element for reducing pumping of one gallon of water
into one revolution of a drive shaft. The shaft extends through a clutch device
and a plurality of injection chambers. The injection chambers supply and meter
the amount of additives injected. Rotation of the shaft through the injection chambers
loads a set amount of additives for suction into a mixing globe. The unloader chamber
controls the spraying cycle and by-pass cycle of fluid flow through the system.
The present invention provides a versatile injection spraying system for multiple
tasks. The types and amounts of additives sprayed can be easily adjusted without
requiring adjustments to sensitive metering or measuring devices.
