Abstract

In an air atomising electrostatic spray gun having a coating material conduit 100, an air hose 40 and a high voltage charging wire 54 connected thereto, the charging wire 54 is housed within the air hose and protected thereby. The wire may be introduced into the hose through tubular fittings attached to the hose and having lateral holes for the ingress and egress of compressed air. A pneumatically operated switch may be provided near the high voltage supply to connect the supply with the charging wire when the compressed air is flowing, e.g. a switch operated by a deformable membrane the opposite faces of which are exposed to pressures in the air conduit on either side of a constriction therein, so that there is a pressure differential across the membrane only when compressed air is flowing to the gun. A helically channelled insert may be provided in the air passage in the gun, and flow of spray material to an annular nozzle 105 controlled by a needle valve which, with a valve in the air passage, is controlled by trigger 76.
