Abstract: The present technique provides a system and for improving control of a needle valve in a spray coating device. An exemplary spray coating device of the present technique has a needle valve assembly that controls entry of a fluid to a fluid delivery tip. The needle valve assembly includes an adjustment element that is at least partially located on an exterior of the spray coating device such that the adjustment element is accessible by an operator. The adjustment element may be actuated to improve a seal around the needle so that fluid does not leak from around the needle valve assembly.

Abstract: A system, including an electrostatic spray system, including an electrostatic tool configured to spray a material with an electrostatic charge, and a controller and wherein the controller is configured to change modes of the electrostatic tool, and wherein the modes are different processes that change the rate of material discharge, how much electrical charge is applied to the material, and when electrical charge is applied to the material.

Abstract: A system is provided for venting a container used to supply a liquid to a spray coating device. The system may include a container cover having a liquid conduit configured to extend into a liquid container, at least one wall surrounding a buffer chamber configured to separate the interior volume of the container from the exterior environment, a first vent conduit that extends into the buffer chamber, a second vent conduit that extends from the buffer chamber to the liquid container, and at least one check valve coupled to either conduit.

Abstract: An electrostatic spray tool is provided to output an electrostatically charged spray. The electrostatic spray tool includes a portable power module. The portable power module includes an air flow switch configured to regulate air flow within the portable power module and a turbine generator configured to generate a voltage from the air flow.

Abstract: A power module of electrostatic tool is provided with an air flow switch. The air flow switch receives an air flow through one passage and outputs two portions of that air flow through two other passages when the air flow exceeds a threshold pressure.

Abstract: A system includes a pressure vessel configured to receive a pneumatic flow, and to supply pressurized fluid to a spray coating device. The system also includes a first chamber disposed within the pressure vessel, and configured to store a first fluid, and a second chamber disposed within the pressure vessel, and configured to store a second fluid.
