Abstract
An improved paint spray gun with a regulated pressure feed paint cup. High pressure air is supplied through a hose and a fitting to the spray gun handle. The air pressure is reduced to a low pressure high volume flow within the gun for atomizing the paint. The inlet of a pressure regulator is connected through a quick connect fitting directly to the gun handle for receiving high pressure air. The regulator outlet is connected through a flexible hose to a barbed fitting on a check valve on a paint cup lid for applying a controlled paint feed pressure to the cup. The location of the regulator does not adversely affect the maneuverability or balance of the gun during use and the regulator can be quickly disconnected from the gun to facilitate cleaning the gun.
