  • Patent number: 4079893
    Abstract: An airbrush includes a body at the forward end of the airbrush and a plume at the rear end, the plume being for balancing the airbrush and supporting it in the user's hand. A source of fluid is included in the airbrush to be dispersed therefrom, and a needle valve through which fluid from the source flows is mounted on the body portion and the source of fluid is also connected to the needle valve. Air in an air passage passes over the needle valve to create a partial vacuum thereover to draw fluid from the source of fluid out of the needle valve and into the stream of air and out of the airbrush. An air valve on the body portion controls the flow of air through the air passage. An air supply provides air to the air passage from a source of air, and the air supply is mounted to the air passage on the plume so that the air valve is spaced from the air supply mounting to minimize the distance from the air valve to the needle valve to decrease the pressure drop between them.
