Abstract: A light assembly coupled to a spray gun for spraying electrostatically charged coating material is disclosed. The spray gun includes a gun body comprising a barrel, a nozzle assembly extending from the barrel in a longitudinal direction, a voltage multiplier, and an actuator assembly configured to transition the voltage multiplier between an activated state and a deactivated state. The light assembly includes a light and circuitry electrically connected to the light. The circuitry is configured to supply electrical energy inductively obtained by the circuitry to the light when the voltage multiplier is in the activated state. The light assembly can also include a housing, a lens cover releasably attached to the housing, and a control member for changing a characteristic of the light.

Abstract: A spray nozzle assembly is provided with an electrode, a wear resistant member, and a compliant sleeve. The wear resistant member supports the electrode and is supported by the compliant sleeve. For coating operations that use abrasive powder such as porcelain enamel, the wear resistant member may comprise ceramic. The compliant sleeve may be made of an elastic material such as plastic, which allows one end of the compliant sleeve to receive an end of a glass powder tube. The wear resistant member may be in the form of a ceramic spider. The electrode may be installed in-line with a powder flow path defined by the powder tube, which extends through a spray gun body.

Abstract: A powder spray gun includes a powder flow path inlet and a powder flow path outlet, the powder flow path inlet being connectable in a first configuration to a dilute phase powder pump and in a second configuration to a dense phase powder pump, wherein the powder spray gun comprises a spray nozzle that is the same for the first and second configurations. The powder flow path is provided by a powder tube that extends through the gun, with the powder tube having a first diameter at an inlet portion of the spray gun and a second diameter at an outlet portion of the spray gun, with the second diameter being greater than the first diameter. The powder flow path may also include a conical transition portion, and a member for adding air to the powder flow.

Abstract: A nozzle assembly for a material application device includes an expansion chamber for slowing down the velocity of powder fed to the nozzle from a dense phase pump. The nozzle assembly includes a nozzle insert that forms the expansion chamber and provides air assist function. The nozzle includes an integral deflector, and further includes a passageway for a charging electrode so that the electrical path is routed away from the powder path, while permitting the electrode tip to be centered in the powder spray pattern from the nozzle. The nozzle also includes air wash for the electrode. The nozzle outlet orifice has a cross-sectional area that is equal to or greater than the inlet cross-sectional area so that a slow moving dense phase powder cloud is produced by the nozzle.
