Abstract: The present technique provides a system and method for improving a tip assembly for a spray coating device. An exemplary spray coating device of the present technique has a twist tip with air-assist channels. The twist tip may be applied to a spray gun and provides a portion of the fluid flow passage of the gun. Rotation of the twist tip alters the fluid flow path, resulting in increased operator control.

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. Furthermore, the system includes a lid removably coupled to the pressure vessel. The system also includes a first fluid pathway extending through the lid, and configured to deliver the first fluid to the first chamber while the lid is coupled to the pressure vessel. In addition, the system includes a second fluid pathway extending through the lid, and configured to deliver the second fluid to the second chamber while the lid is coupled to the pressure vessel.

Abstract: The present technique provides a system and method for improving atomization in a spray coating device. An exemplary spray coating device of the present technique has a fine finish tip with an atomization section comprising a first fluid impingement orifice, i.e., a pre-orifice, angled toward an expansion chamber and a subsequent second fluid impingement orifice. The fine finish tip is provided as a unitary assembly that may be applied to a spray gun and that provides a fixed relationship between the pre-orifice, the expansion chamber, and the second orifice, which results in refined spray characteristics, such as uniform particle distribution and uniform fan pattern shapes.

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 fluid pressure regulator, for controlling the pressure of fluid in accordance with the pressure of an air signal, is characterized by a housing having a chamber divided into fluid and air chambers by at least two flexible diaphragms. The fluid chamber has a valved inlet for connection with a supply of fluid at an elevated pressure, and an outlet. The air chamber has an inlet for receiving an air signal at a selected pressure. A valve is moved by flexure of the diaphragms to open and close the fluid inlet, so that the pressure of the air signal regulates the pressure of fluid in the fluid chamber and at its outlet. A space is defined between the diaphragms, and vents extend from the space to exterior of the housing. Should the diaphragm on the fluid compartment side rupture, fluid entering the space will flow through the vents and provide a visible indication of diaphragm failure, but the diaphragm on the air chamber side will prevent fluid from entering that chamber.
