Abstract

1278138 Spray producers ATLAS COPCO AB 25 Sept 1970 [6 Oct 1969] 45690/70 Heading B2F A hand held spray gun has spraying material supplied to it through a hose 16 from a receptacle 19 including an ejector 24, the ejector tube 20 being supplied with compressed air via a pressure reduction valve 18, the degree of pressure reduction being controlled by a trigger 14 on the gun via a second pressure reduction valve 31 in the gun, this being supplied with compressed air by a conduit 15 and connected to a balance chamber 29 in the first pressure reduction valve by a conduit 17. The first pressure reduction valve 18 is supplied with compressed air from a conduit 22, a valve body 25 connected to a diaphragm 21 urged against a valve seat 26 by a spring 27, preventing the flow of gas to chamber 28 and the ejector 24 unless there is compressed air in the balance chamber 29 acting against the diaphragm 21 to open this valve. The pressure of air from the conduit 17 in the chamber 29 also determines the size of chamber 28 as a result of the movement of the diaphragm 21 and consequently controls the amount of pressure reduction in valve 18 and so controls the pressure of air supplied to the ejector. The pressure of air in conduit 17 is controlled by the trigger 14 acting through an adjusting spring 6 and a valve lifting finger 18 on a valve body 8, the degree of compression of this adjusting spring 6 determining the pressure of air delivered from conduit 15 to conduit 17 and thus the trigger 14 determines the flow of spray material from the ejector 24. A fine pressure equalisation opening 30 in balance chamber 29 allows the release of pressure from this chamber. In the embodiment described the spray material is charged electrostatically, this being by way of a high voltage supply cable 9 to the gun. The gun may be used to spray such materials as paint powder, concrete, fiber cuttings, sand and steel blasting grit. When the gun is not adapted for electrostatic spraying the spray may be assisted by auxiliary pneumatic spray nozzles at the tip of the gun.
