    Abstract: A fluid supply and reservoir is proved which may be used in conjunction with a clothes refreshing appliance. A fluid cartridge has a top wall to which the nozzle assembly may be secured, and a supply of pressurized air is connected to the nozzle assembly to draw fluid from the reservoir into the nozzle assembly through a siphon tube by a venturi action. The air supply may be provided through an air supply arrangement which includes guide walls for positioning the nozzle assembly relative to the air supply, and a resiliently mounted air supply tube for mating with an air supply opening in the nozzle assembly. An arrangement may also be provided in the reservoir to assure a constant fluid pressure therein to provide a constant flow of fluid through the nozzle assembly.
