Abstract
A powder spray gun which, in the presently preferred embodiment, is particularly adapted for spraying a particulate powder spray onto the interior surfaces of containers and other target objects in a confined area. The apparatus includes a rigid tubular support member and a flexible powder transport tube. The rigid support member carries a high voltage cable having a charging electrode at one end. The flexible tube terminates in a discharge nozzle which may be adjustably mounted to the support member adjacent the charging electrode so as to permit variation of the angle at which the powder is released from the nozzle relative to the longitudinal axis of the support member. Intermediate the discharge nozzle and an upstream portion of the powder transport tube which is connected to the support member, the flexible tube is smoothly curved so as to prevent any sharp corners in the transport tube or the nozzle within which powder could collect and interrupt smooth, even discharge of powder from the gun.
