ABSTRACT:
A hydraulically assisted high volume low pressure air spray gun has an airless tip for hydraulically emitting a fan-shaped pattern of liquid coating material, an atomizing air orifice for emitting air to pneumatically break up the pattern of coating material into a fan-shaped atomized spray and opposed side port air orifices for emitting jets of air that impinge against opposite sides of the spray. The gun received coating material at pressures in the range of about 25 to 1000 psi and air at pressures up to about 60 psi. An air flow restrictor limits the pressure of air at a spray head of the gun and a valve for controlling the flow rate of air to the side port orifices also simultaneously controls the flow rate of air to the spray head to limit the pressure of air at the spray head to no more than a selected maximum pressure, despite changes in the flow rate of air to the side port orifices. By virtue of the coating liquid being hydraulically emitted from the airless tip in a fan-shaped pattern, less pneumatic energy is required to fully atomize the coating and improved atomization is obtained for a given pressure and volume flow rate of air at the spray head.
