Water well with fountain and two superimposed discs

摘要

The lower disc (14) is fitted with through nozzle bores for pressurised water flow from underneath to generate upwards directed water jets. The shape of the two discs so coincides that at least a part of the bores (40) is alternately covered and released for generating the fountain effect on the top disc (12) rotation. At least a part of the other bores (30) generates water jets lifting the top disc. Pref. both discs are of the same basic shape, with the top disc contg. a recess for forming the water fountain. The discs may be circular, or both of a shape differing from the circular one.
