摘要： A tribo-electric powder spray gun includes a diffuser for mixing powder with a conveying gas, a charging portion downstream of the diffuser, and a sprayhead at the outlet of the charging portion for dispensing the charged powder. The charging portion has an inner core removably positioned within a hollow outer cylinder with an annular gap formed between the outer cylinder and inner core providing a charging flowpath for the powder. The inner core and the outer cylinder have undulating or wavy charging surfaces made of an electrically insulating material, so that the annular gap provides a tortuous path for the powder, enhancing powder contact and the charge imparted to the powder. Grounding is provided by surface conduction of the electrically insulating contact material through a ground ring located outside the powder path at the inlet to the charging portion of gun where the greatest amount of charging occurs. By locating the ground ring outside the powder path, the ground ring is kept clean and the amount of charging surface is maximized. The inner core and the outer cylinder are longitudinally symmetrical to facilitate re-assembly.

摘要： A mounting assembly for adjustably mounting a spray gun onto a mounting bar comprises a ball-and-socket joint attached at one end to the bar and attached at the other end to the gun, and an adjustment sleeve extending along the exterior of the bar. The sleeve is attached to the ball-and-socket joint and adapted to tighten the socket around the ball when the sleeve is turned to retain the gun securely in a desired position with respect to the bar. The mounting assembly allows for positioning the spray gun in an almost limitless range of possible orientations, and allows the securing mechanism to be easily tightened and loosened by the operator by turning the adjustment sleeve. An anti-back-ionization probe is attached to the gun and extends externally to the gun along the top or side of the gun. The probe comprising an elongated rod, which is easily removable and easily adjustable in length.

摘要： A hand-held powder spray gun includes a wand type handle that extends from the top of the handle and away from the rear of the gun, which provides for ergonomic operation of the gun. The wand handle can be converted to a pistol handle by removal of the handle from the gun body. The parts of the wand handle and the pistol handle are interchangeable to facilitate conversion and repair. The wand handle can be used with a diffuser having hose connections extending from the rear of the spray gun to make the gun easier to operate when held from above. A diffuser having hose connections at the bottom is also provided for use with a pistol type handle.

摘要： A particle spray apparatus includes a spray gun having a deflector connected with a housing assembly. An electrode arrangement extends from the housing assembly into the deflector and is exposed to the flow of air with particles entrained therein to electrostatically charge the particles. The electrode arrangement is exposed to a flow of fluid to remove contaminants which may accumulate around components of the electrode arrangement. Accumulation of particles on an end surface of the deflector is discouraged by a flow of fluid from a chamber in the deflector through a porous member. The flow of fluid from the chamber is also conducted through a porous electrode sheet which extends along the porous member. Due to the relatively high voltage conducted through the electrode arrangement, an arc may tend to form in a passage along which fluid is conducted to the electrode arrangement. To prevent this from occurring, the passage through which fluid is conducted to the electrode arrangement is relatively long.
