<p>Apparatus for spraying a range of mixtures of two or more fluids, comprising: a body defining a passageway for conveying gas flowing through the body from an inlet to an outlet, the outlet comprising at least two apertures; at least two fluid supplies (120A, 120B,...), one for each aperture, with each configured to deliver fluid to a respective entrainment region (R) where it will become entrained in gas flowing from its respective aperture, at least one fluid supply being configured to receive fluid from a reservoir (22A, 22B, ...) comprising a wick (70) extending to or immediately adjacent the entrainment region (R); and a regulator for regulating gas flow through each of the apertures, whereby relative quantities of fluid from the respective fluid supplies (120A, 120B, ...) entrained in gas flowing from the outlet is dependent upon regulation of gas flowing through the apertures.</p> |
