Abstract

The spray painting gun includes an electric supply allowing air and paint to be simultaneously heated. A diffuser includes a removable part forming the jet, and a second part enabling the jet to be adjusted to a range of angles. The jet has an independent supply of air. The gun includes a valve driven alternately by the axle of a motor, and by a pawl mechanism. A reservoir is attached to the body of the spray gun. The heater comprises a chamber with a central hub and a number of vanes attached to the hub. These serve as supports for resistance heating elements, air passing through the channels formed between the vanes and the wall of the chamber. A thermostat bulb housing a bimetallic strip controls the power supplied to the heating resistances.
