The machine consists of a motor/blower assembly, a nozzle system, nozzle

housing, a formulation tank and a metering valve. The various components are

identified in a diagram below. The blower is a single stage/centrifugal

impeller/axial flow driven by a universal motor operating at a speed of about

20,000 RPM. The blower moves a large amount of air through the nozzle system

consisting of three individual nozzles, each of which has two sets of directing

vanes. One vane set causes the air to be rotated clockwise and the other causes

the air to be rotated counterclockwise. The intersection action of the circula r

forces shears the material being dispensed into small particles. Further, the ai r

rushing by the specially shaped liquid tubes creates a negative pressure in the

liquid tube. This negative pressure causes the liquid to be drawn from the

formulation tank through the control valve and into the nozzle system where it is

pneumatically sheared into aerosol or mist size droplets. After break-up, the

droplets are driven away from the machine by the air passing through the nozzle

system.

Generally, the size of the output droplets increases with increasing

flow rate and with increasing viscosity.
