Abstract: A spray gun includes a main body and a spray head. The spray head has an air cap, a hollow nozzle member having a nozzle tip for dispensing a liquid to be sprayed. The hollow nozzle member has a radially extending weir which together with a surface of the main body defines an air distribution chamber for receiving and distributing compressed air from a supply inlet. An annular sealing member is sealingly disposed between the radially extending weir and the surface of the main body, dividing the chamber, so that air passing into the chamber through an opening to one side of the annular wall is directed to a central aperture of the air cap and air passing into the chamber through an opening to the other side of the annular wall is directed to lateral apertures of the air cap.

Abstract: The invention provides a spray gun comprising a main body 2, a spray head 6, an inlet 12 for a liquid to be sprayed, and an inlet 10 for a supply of a compressed air;

Abstract: An improved spray gun having an aluminum gun body and a sprayhead made of a plastics material, preferably of polybutylene terephthalate. The sprayhead is permanently secured to the spray gun body, preferably with a swaged ring of stainless steel. The spray gun may be provided with a plastic handle which is preferably formed from polybutylene with 10% of a polyester elastomer. In one embodiment, the sprayhead is oriented relative to the gun body prior to securing to select either gravity feed or suction feed for the sprayed fluid.
