Abstract

A spray gun includes several atomizer and a plurality of conduits communicating therewith for supplying different coating materials. A valve needle is disposed in each supply conduit, such needles being individually controlled by pneumatic cylinders. In one embodiment the supply conduits are oriented at an acute angle relative to the axis of the gun barrel. In a second embodiment the supply conduits curve away from such longitudinal axis, with the valve needles formed of elastic material. In a third embodiment the supply conduits extend parallel to the longitudinal axis of the barrel, with the pneumatic cylinder oriented at a right angle relative to the valve needle and connected thereto by means of a knee joint.
