Pressure vessel for voltage block material supply system

A pressurizable supply vessel to receive and retain a supply of electrically conductive liquid material and for use in a high voltage electrostatic paint spray system including a supply system provided with means to prevent electrical current passage therethrough, said vessel characterized by

• a. a cylindrical body supported in vertical axial orientation,
• b. a pair of end caps comprised of electrically insulating material disposed in fluid sealing engagement with said body at the top and bottom ends thereof,
• c. inlet means in said top end cap for receiving said electrical conductive material,
• d. said inlet means including a tube comprised of electrical insulating material, said tube extending lengthwise of said body, downwardly into said vessel,
• e. said tube terminating in a discharge opening spaced at predetermined minimum distances from the walls of said cylindrical body, and said top and bottom end caps, whereby said discharge opening is spaced beyond the arcing distance for voltages utilized in said electrostatic paint spray system, and
• f. outlet means in said bottom cap.
