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.

Spray gun

A multi-component feed system to feed two fluid materials from a feed tank to a spraygun is described. The combined pressure feed tank comprises a pressure feed tank with a lid. Inside the tank is a removable support structure having a cone-shaped member with a central chamber supporting a second container closed by a lid. A splash-proof membrane extends between the inner wall of container and the outer wall of container to protect a second fluid component, e.g. a catalyst from entering the lower chamber of tank. Air is fed to containers and via a regulator, a regulator pipe and through an aperture in the lid. Pressure air feeds the fluid components via tubes to a spray gun, where the components combine to be sprayed.
