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.

Powder gun configurable for supply from venturi or dense phase pump

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.

Powder spray gun component

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.

Retrofit light assembly and powder spray gun with integrated or retrofit light

Control method and apparatus for a manual spray gun includes display that is disposed on the spray gun and that provides information to an operator about one or more coating operation parameters. An auxiliary trigger may be used that enables an operator to makes selections of one or more coating operation parameters. The display and auxiliary trigger together permit an operator to make selections without having to divert attention or field of view away from the spray gun or the coating area, especially during a coating operation.

Control function and display for controlling spray gun

Powder gun configurable for supply from Venturi or dense phase pump

A selectively configurable spray gun may include a gun body comprising a selectable forward section and a rearward section. The rearward section may be connected with either of two or more selectable forward sections so as to selectively configure the spray gun to operate either with a dense phase powder supply configuration or a with dilute phase powder supply configuration. The rearward section may include a selectable powder flow path that is connectable at an inlet end to a source of dense phase powder and at an outlet end to a selectable spray nozzle in the selectable forward section that may optionally include a diffuser. An adapter may be used to connect the rearward section with a selectable spray nozzle or air cap. A manual spray gun embodiment is also presented. A selectively configurable spray gun for use with a dense phase powder supply may include a smaller diameter powder tube that extends through a larger diameter powder tube.

Dense phase or dilute phase delivery through a powder gun

Control method and apparatus for a manual spray gun may include a second manually actuated trigger disposed on the spray gun handle, with the second trigger being operational to select one or more coating operation parameters.

Coating material spray gun

Purge method and apparatus for a manual spray gun or coating material application device, in which purge air is introduced into the device through a handgrip portion that is manually held during a coating operation. Purge air first enters the coating material flow path after the purge air enters the handgrip portion.
