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： An electrostatic spray gun apparatus includes a spray gun housing and a nozzle attached to a spray end of the housing, and a powder path that extends in a substantially straight line along an axis of the housing from the powder inlet to the powder outlet. The powder path is in the form of an enclosed smooth powder passage that is substantially continuous and uninterrupted from the powder inlet to the powder outlet to eliminate substantially all recesses or gaps that could capture or trap powder. The powder passage is formed by a plurality of tubular segments that are aligned along the housing axis and abut end to end, that when assembled in the housing axially compress the segments together to substantially eliminate dead spots or recesses to form the continuous smooth powder path. A gun purge function is provided that allows a purge line to be installed on the gun assembly. A cartridge valve and conductor assembly is provided between the gun electrode in the nozzle and the output of the voltage multiplier. The cartridge includes a conductive path to provide electrical continuity from the multiplier to the gun electrode, and also includes valve, preferably in the form of a stem check valve, that closes when the gun electrode is removed or at least unseated from the nozzle. The gun also includes a tube mount arrangement wherein the tube mount is rigidly held together with the gun housing in axial compression by a tie bar.

摘要： Electrostatic liquid spray coating apparatus including a rotary atomizing cup of insulative material driven by an air turbine, is provided with a semi-conductive charging device extending through the cup, the inner portion of which is proximate the inner surface of the cup for contact charging liquid coating material supplied to the rear of the cup as it flows forwardly and outwardly over the rotating cup interior and contacts the charging device prior to atomization at the forward edge of the cup. A generally cylindrical insulative support body, housing a turbine and its associated air bearing and cup drive shaft, has a reduced diameter intermediate section which provides an annular cavity in which are located liquid coating and solvent valves for controlling the flow of liquid coating and solvent to the cup. The charging means in the cup is energized via a stationary conductor which terminates in closely spaced proximity to the outer portion of the charging device on the cup exterior which is electrically connected to the inner portion of the charging device on the cup interior via a series of semi-conductive posts which form the portion of the charging device extending through the wall of the cup between its inner and outer surfaces.

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.
摘要翻译： 颗粒喷雾装置包括具有与壳体组件连接的偏转器的喷枪。 电极布置从壳体组件延伸到偏转器中并且暴露于夹带有颗粒的空气流中以对颗粒进行静电充电。 电极装置暴露于流体流中以去除可能积聚在电极装置的组件周围的污染物。 通过流体从偏转器中的腔室流过多孔构件而阻止在偏转器的端面上的颗粒的积聚。 来自腔室的流体流也通过沿着多孔构件延伸的多孔电极片进行。 由于通过电极布置传导的相对较高的电压，可能趋于在流体被导向电极装置的通道中形成电弧。 为了防止发生这种情况，流体通过其传导到电极装置的通道相对较长。

摘要： An improved apparatus for applying coating material includes a spray head having a housing which encloses a deflector. The deflector and housing cooperate to form a plurality of coating material flow channels which diverge in a direction of flow of coating material through the spray head. The deflector and housing cooperate to define a long thin outlet with relatively wide channel outlet sections at opposite ends of the outlet. An electrode assembly includes an electrode element having a long thin surface area which extends between opposite end portions of the long thin outlet and is exposed to the flow of coating material through the outlet. A wear tube encloses a portion of the electrode assembly and connects the deflector with the housing. The electrode element may be a plate which is molded into the deflector with a minor edge portion of the plate exposed to the flow of coating material.
