Abstract (en)
A pneumatic/hydraulic wave generator for a swimming pool includes a plurality of caissons communicating with the deep end of the pool through a submerged passage. A pneumatic system includes a motor-driven impeller fan housed horizontally within a manifold housing and communicating with duct lines to the caissons through pneumatic valve assemblies. Each valve assembly includes a pendulum sleeve having a butterfly valve mounted therein that is actuated by swinging movement of the sleeve between an open and a closed position. Disposed within an upper air chamber portion of each caisson below an associate caisson valve assembly is a dispersion grate for evenly distributing air from the valve assembly across the upper surface of water disposed within the caisson. <IMAGE>
