ILLUMINATED FOUNTAIN Russian patent published in 2006 - IPC B05B17/08 

FIELD: hydraulic structures, particularly decorative illuminated fountains with changeable spray and lightening.

SUBSTANCE: illuminated fountain is provided with body having opened top and bottom orifice, as well as control unit for liquid supply regulator arranged at liquid inlet of accumulation chamber. The accumulation chamber is arranged in lower body part, which communicates with elevated pressure chamber through annular transition member. The elevated pressure chamber is connected with annular slot-like liquid outlet defined by two conical surfaces. The first conical surface is arranged in upper body part, the second one is made as part of outer surface of liquid receiver formed as hollow truncated cone. The lesser base of the truncated cone is connected to hollow cylinder. Liquid receiver is inside the body and extends along body axis so that cylinder orifice coincides with the orifice formed in body bottom. Radius of annular slot-like outlet, angle of slot inclination relative device axis and width thereof are selected to provide acute angle between initial spray part and device axis, to provide following change in spray direction and falling thereof into funnel-shaped liquid receiver.

EFFECT: simplified structure, increased appearance due to possibility to combine fine spray shape and original illumination, possibility of fountain usage in the case of low stray light or in the absence thereof.
