Filed:

Mar 9, 2000

Appl. No.:

09/521746

Inventors:

Ronald J. Hartle - Amherst OH
David L. Mancini - Westlake OH
George C. Ehrnschwender - Amherst OH

Assignee:

Nordson Corporation - Westlake OH

International Classification:

B05B 500

US Classification:

239691, 239705

Abstract:

A modular spray gun that can be configured and built to operate using a selectable spray process. The modular spray gun includes a gun body, an extension and a selectable spray atomizing component. The basic gun body and extension are used to configure a spray gun that can operate as an air spray gun, an airless spray gun, an AAA gun or an HVLP spray gun. The modular extension can be selected to allow circulating or non-circulating operation. The modular extension also permits a variety of spray nozzle assemblies to be mounted thereon depending on the selected spray process to be used with the specific gun. The modular gun body allows selective connection of an atomizing air supply and additional components specific to a particular spray process. An indicator device and/or a relief valve is provided for spray guns using an HVLP spray process to provide an indication that the spray gun is in compliance with the maximum nozzle air pressure limit, usually less than 10 psi. A new air valve seal assembly is also provided.
