Abstract
A plural component air spray gun is characterized by a spray head assembly that has a pair of hemispherically shaped fluid outlet orifices, the straight sides of which are facing, parallel and separated by a relatively thin wall. Each orifice receives a respective one of two liquid materials delivered through associated liquid supply passages, and the passages are inclined so that streams of liquid emitted from the orifices come together a short distance beyond the orifices. Air emitted from an atomizing air orifice surrounding the two fluid orifices mixes and breaks up the liquid material streams into an atomized conical spray. To form the conical spray into a fan-shaped pattern, an air cap directs air jets against opposite sides of the spray.
