Turbo spray nozzle and spray coating device incorporating same

A spray coating system, comprising:

• a spray gun coupleable to a source of pressurized air and to a source of pressurized coating material;
• and
• a turbo spray nozzle coupleable to the spray gun to enable the turbo spray nozzle to receive pressurized air and pressurized coating material from the spray gun, the turbo spray nozzle comprising:
• a rotatable shaft having a center bore, wherein the rotatable shaft is driven into rotation by the pressurized air from the spray gun and the spray gun is configured to direct the pressurized coating material into the center bore as the rotatable shaft rotates.

A kit for converting a spray coating device that utilizes pressurized air to atomize a coating material to a spray coating device that does not use pressurized air to atomize a coating material, the kit comprising:

• a rotatable shaft comprising:
• a center bore extending axially though at least a portion of the rotatable shaft and;
• a plurality of grooves located on an outer surface of the rotatable shaft and in fluid communication with the center bore;
• and
• a movable sleeve selectively securable to the rotatable shaft over the plurality of orifices.

A method of atomizing a liquid, comprising:

• rotating a shaft having an axial passageway extending through a portion of the shaft;
• directing a flow of liquid to the axial passageway of the rotating shaft to induce a helical flow in the flow of liquid;
• and
• directing the flow of liquid from the axial passageway to a plurality of grooves located on an outer surface of the shaft through a plurality of orifices extending outward from the axial passageway to the plurality of grooves.
