ABSTRACT:
A spraying device comprises a nozzle casing surrounding an interior which holds a nozzle block and a conduit coupler therein. The nozzle block and the coupler are axially aligned, a front wall of the coupler facing a rear wall of the nozzle block. The nozzle block and the coupler are relatively rotatable, enabling the front wall of the coupler to rotate relative to the rear wall of the nozzle block. A plurality of spray pattern forming apertures pass through the nozzle block, from the rear to the front wall thereof. A fluid passage in the coupler has a liquid outlet on the front wall of the coupler that is sealingly disposed against the rear wall of the nozzle block, eccentrically to the axis of rotation of the coupler in a manner which permits the liquid output to be brought into fluid communication with any one of the spray generating apertures. A comparatively large cylindrical bore which extends along the axis of the nozzle block forms a chamber which is open to the front wall of the nozzle block and is in fluid communication with one of the apertures. The chamber is designed to interchangeably hold therein either a nozzle insert which serves to generate one particular type of spray or a turbo assembly for generating a turbo or rotating liquid jet.
