Abstract: In a powder spray device for the electrostatic coating of workpieces with powder at least partly comprising electrically conductive particles and having a powder channel (10) for delivering the powder to an outlet directed towards the workpiece the powder channel contains a local cross-sectional reduction. The cross-sectional reduction brings about a velocity increase of the powder in the powder channel, thereby preventing an adhesion of the powder to the inner wall of the powder channel.

Abstract: A diffuser comprises a conduit having a cross-sectional area that increases in a direction fluid flow. In one embodiment, the diffuser is used to reduce the incidence and severity of flow fluctuations that occur in an electrostatic deposition apparatus. In some embodiments, the diffuser includes one or more flow control features. A first flow-control feature comprises one or more appropriately-shaped annular slits through which fluid having a greater momentum than a primary fluid moving through the diffuser is injected into the “boundary layer” near the wall of the diffuser. A second flow control feature comprises one or more annular slits or, alternatively, slots or holes that are disposed at appropriate locations around the circumference of the diffuser through which a portion of fluid flowing in the boundary layer is removed. Boundary-layer flow removal is effected, in one embodiment, by creating a pressure differential across such annular slit or slots. Among other benefits, such flow control features reduce any tendencies for flow separation of the primary fluid in the diffuser.

Abstract: 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. The gun may further include a nozzle that provides a directional spray pattern to one side of the nozzle thereby allowing the gun to easily spray non-vertical surfaces.

Abstract: The invention relates to a high-voltage powder spray gun, in particular for spraying metallic powders. The rear terminal segment (60) of a powder tube (38) and the front terminal segment (58) of a hookup tube (56) are inserted far enough in axial and sealing manner to subtend between their overlap ends (69, 78) a powder-tight, electrically insulating expanse (76) to preclude electrical leakage currents. An electrically conducting bush (42) runs over the outer overlap end (78) of the hookup-tube/powder-tube connection to shunt any electric charges that might issue at the outer overlap end (78) between the hookup tube (56) and the powder tube (38). This powder spray gun preferably also is fitted with an electrically grounded shielding sheath (90), preferably a helical compression spring, which is configured radially away above the outer overlap end (88), said sheath being configured between the rear terminal segment of the hookup tube (56) and the front end of powder hose (84) slipped over said rear terminal segment. This configuration prevents arcing on the hand of an operator in the event electric charges were to issue between the powder hose (84) and the hookup tube (56).
