ABSTRACT:
A spray arrangement including means to form and direct a spray of liquid droplets and means to apply an electrostatic charge to droplets in said spray, said charge applying means including an insulating body to support a spray-charging electrode in association with the spray-forming means, the spray-forming means [10] forming the spray hydraulically, the body [20] having a smoothly-constricted bore [26, 27, 28] for the free passage of spray with the electrode [23] housed to expose only inward-facing electrode surface [28] as the constriction to passing spray [40] for the acquisition of charge therefrom, the bore surface turning back upon itself [29] as it expands beyond the constriction to form an end of the body, the end of the body where the surface turns back upon itself [29] and the part of the bore remote from said end being formed to assist the shedding of liquid [22, 51, 52]. The arrangement is suitable as a dairy sprayer to direct charged spray upwardly from said turned-back end on to the teats and udder of a dairy animal such as a cow, ewe or goat.
