ABSTRACT:
An air distribution valve comprises a gimbal mounted flow directing nozzle connected to a feed conduit and selectively and pivotally advanceable about at least two intersecting and perpendicular axes into alignment with one of four outlet openings in a base plate each opening to an outlet conduit. The gimbal includes an outer gimbal ring supported in horizontal alignment above the base plate and an inner gimbal ring pivotally mounted to and inside the outer gimbal ring and rotatable about a first axis. The flow directing nozzle is pivotally mounted on mounting arms pivotally connected to the inner gimbal ring and pivotal about a second axis which intersects and extends perpendicular to the first axis. When used in a wave generating system, each outlet conduit communicates with one of four caissons at one end of the wave pool for selectively delivering pressurized air to the caisson from a centrifugal fan to force water out of the caissons in a selected order to create a desired wave pattern.
