Abstract A swimming pool system including an inlet conduit around the walls of the pool having spaced apart outlet openings directing fountains of water upwardly and inwardly for cooling in the night air and for providing a decorative fountain affect around the periphery of the pool. The inlet conduit is comprised of a plurality of sections each of which is connected to a control flow valve having a continuously rotatable valve element. The valve element is cylindrical and hollow and includes a series of peripheral rows of openings registerable with the inlet conduit sections. Each of the successive openings in the rows are different in shape and size to provide a continuously varying pattern of fountain activity. A reciprocal power means may be provided for reciprocating the cylindrical valve element such that different peripheral rows of openings register alternately with the sections of inlet conduit to further vary the pattern of fountain activity. A vane structure may be provided on the inlet end of the cylindrical valve element to cause the inlet water pressure to continuously rotate the valve element.
A control flow valve assembly comprising, a housing having an inlet opening and a plurality of outlet openings, a hollow cylindrical valve element in said housing and said inlet opening being in communication with the interior of said hollow cylindrical valve element, said valve element being completely open along its entire axial length, means for continuously rotating said valve element, a plurality axially spaced apart rows of peripheral openings in said valve element and a row of openings being successively registrable with each of said outlet openings, reciprocal power means being provided for moving said valve element longitudinally such that each outlet opening is alternately aligned with different rows of openings, said openings in adjacent rows being successively different in shape and size to provide different flow patterns, and said means for continuously rotating said valve element comprising a vane means being provided at the inlet end of said valve element and connected directly thereto to react with an inlet pressure source to turn said valve element and vane as a unit about a common longitudinal axis.
