<p>SPECIFICATION SPRAYING APPARATUS AND ADAPTOR WITH EXPENDABLE VALVE ASSEMBLY A valve assembly which mixes two components for delivery to a spraying apparatus. The assembly is comprised of a core valve mounted in a housing or body which is secured in a chamber in a manner which provides passageways between the housing and the chamber. A fluid is delivered to the core valve by a first conduit attached to the housing, while air is delivered to the chamber by a second conduit coaxial with the first attached to the chamber. The core valve is operated by a plunger or push rod which opens the valve permitting the fluid to enter the chamber and causing it to be mixed internally with the air for delivery to a spraying nozzle device. The valve assembly is operated simultaneously with the valves of the spraying device and may be incorporated into the spraying nozzle device or provided as an attachment thereto. The valve is also incorporated into a spraying apparatus with an internal fluid mixing chamber which simultaneously mixes two fluids, then delivers mixture to a nozzle for blending with another fluid component. The spraying apparatus is comprised of a gun body with an integral fluid mixing chamber, a nozzle body attached to the gun body, and a nozzle configured to blend two fluid components coming from the nozzle into a uniform spray. The nozzle body is connected to the gun body by a hollow tubular nut, having a threaded nipple as a conduit for delivery of a fluid. The nozzle body has a passageway in communication with the hollow nut for delivering the fluid to a chamber and valve connected to a central aperture of a nozzle removably attached to the nozzle body.</p> |
