ABSTRACT:
The spraying device comprises: a tubular body which defines a chamber connected to a supply of water under pressure, a nozzle (1) with atomizer and a constriction organ in the form of a valve (6) in order to form a thin-walled hollow jet. The orifice (7) of the nozzle comprises a surface shaping the jet which is arranged to produce at the level of this latter an asymmetry of rotation. The spraying device preferably comprises two nozzles centered in the same plane and forming between them an angle which is of the order of 80°. The valves of these two nozzles are controlled simultaneously by appropriate elements.
