ABSTRACT:
A paint cup adapted to be carried by a spray gun for use with coating materials requiring stirring to prevent separation. A reservoir is closed by a cover member which is mounted on the spray gun and, which in turn, mounts an agitator which projects into the reservoir. The agitator is driven by compressed air admitted to an impeller housing on the cover member. The reservoir is sealed except for means to introduce air to replace the coating material used in operation, and in this invention the air is introduced primarily through a separate check valve. Discharge ports in the impeller housing are made sufficiently large to assure at least atmospheric pressure in the reservoir. A separate check valve is provided to maintain the pressure within the reservoir at atmospheric pressure while preventing material leakage from the reservoir. The design of the cover assembly and its controls ensures easy flushing of the components with or without disassembly.
