Abstract
Abstract A water distribution apparatus employs a self-positioning water flow actuated rotor for serially channeling water flow into each of a plurality of outlet conduits from a common source of water under pressure. The rotor, housed within an encapsulating cavity, includes a hollow hub closed at an end and having the other end in fluid communication with the source of water under pressure. A plurality of jets eject water from within the hub intermediate a pair of hub mounted discs and provide motive power for rotating the rotor. Opposed apertures in the discs provide fluid communication between the jets and serially with a selected pair of opposed outlets connected with one of the outlet conduits; the rotational positioning of the rotor corresponding with a pair of outlets is regulated by a timed solenoid. Axial centering of the rotor within the cavity intermediate the opposed pairs of outlets is provided by the water pressure acting on the closed end of the hub in conjunction with bearing members defining the limits of the hub's axial movement.
