More Information
Summary:Spray device 2 comprising an outlet 12 with an adjustable cross section, a cyclone chamber 4 connected to the outlet and at least one inlet (6,8 Fig.1) for connection to a fluid source. The cyclone chamber further comprises a cross sectional area which decreases in a direction away from the outlet and a closed base 10. In use, at least one fluid entering the chamber forms a reverse flow cyclone in which the fluid travels in a first direction away from the inlet(s) to the base of the chamber and thereafter reverses direction and travels towards the outlet, forming a spray. The spray is emitted from the outlet wherein the size of the cross sectional area of the outlet varies depending on the pressure of the fluid(s) entering the chamber. The outlet may be completely or partially formed of a flexible resilient material portion 14, 20. The outlet may comprise an outer rigid wall (18, fig.6) and a flexible resilient inner portion 14. The outlet cross section may have an hourglass profile. The chamber may be provided with an extended outlet with a fixed or adaptable cross sectional area similar to that of the outlet.
