Swimming pool water circulation system

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.
