ABSTRACT:
This disclosure relates to a manually operated, self-cleaning, aerosol valve that is adapted to maintain separation of fluids while they are within the valve body. The valve is internally separated by a sealing gasket that cooperatively engages a valve seat, and an outwardly projecting discharge passageway stem member. When the valve is in a nonoperating state, engagement of the gasket with respect to the valve seat prevents discharge passage of a first fluid to the stem passageway, and engagement of the gasket with respect to the stem prevents discharge passage of a second fluid. In cofluid dispensing state, first and second ports into the stem discharge passageway are positioned on opposite sides of the gasket. This allows first and second fluids to separately enter the stem passageway, and maintains separation of fluids awaiting discharge. When the valve is operated in positions intermediate the shut and cofluid dispensing state, both first and second fluid ports are positioned to receive first fluid only. Thus, in intermediate operating positions of the valve, first fluid can purgingly pass through both fluid ports and stem passageway to effect self-cleaning, and separation of fluid awaiting discharge can still be maintained.
