Abstract: An airbrush as used for a media delivery system comprises an air pressurizer, a power source and a media reservoir integrated into a single hand held device. The air pressurizer comprises a pump and motor assembly delivering pressurized air by way of first and second air conduits to a nozzle.

Abstract: In an aspirating and dispensing/spraying device, a holder is screwed onto a tube, connected to a liquid supply line, in such a way that it is displaceable along the tube by rotation. The tube is surrounded at a distance by a coaxial sleeve, which is solidly anchored in the holder, having a discharge opening on its front end, which is conically narrowed, whose edge surrounds the front end of the tube, which carries a outlet opening, separated by a narrow annular gap from the tube. The sleeve carries a connecting piece laterally, to which a pressurized gas supply line is connected and which discharges eccentrically into the space between the sleeve and the tube, so that pressurized gas flowing in receives angular momentum. When the gas flows out of the annular gap, it mixes intensively with the liquid coming out of the outlet opening and forms a discharge cone made of a fine, symmetrical aerosol with the liquid.

Abstract: An apparatus for adapting a blower system to the dispersing of liquid material is partially housed within an extension tube of a portable blower and includes a pressurizing tub with an inlet for accepting airflow discharged by the blower. The pressurizing tube discharges into a liquid container thus increasing pressure within the container. An extraction tube exits the container and meets a Venturi tube that also accepts airflow discharge by the blower. A vacuum is created in the extraction tube through first and second apertures that allow fluid communication between the Venturi tube and the extraction tube. The vacuum created in the extraction tube extracts liquid from the liquid container and the liquid is drawn out of the extraction tube through the Venturi hole into the Venturi tube mixing with air flowing there through and discharging into airflow by-passing the spray adapter apparatus.

The reservoir has a removable lid and is capable of standing, inverted, on its own so that it can be filled with fluid. The lid also functions to secure the liner in the reservoir and, at the end of a spraying operation, the lid and the liner are removed together from the reservoir and discarded, thereby simplifying the cleaning of the spray gun.
