Abstract
A four-way air directional valve assembly is disclosed in combination with apparatus employed for pneumatically generating waves in a wave pool having a plurality of wave generating chambers arranged side-by-side and extending across the width of a pool at one end thereof. Each of these wave chambers has a below the water passageway in communication with the pool and a sealed portion located above the normal water level of the pool. Each chamber has an inlet-outlet passageway above the water level with the passageway serving in one mode as an inlet for directing forced air into the wave chamber and in a second mode as an outlet for exhausting air therefrom. The air directional valve assembly provides communication between a source of forced air and with associated pair of inlet-outlet passageways communicating with adjacent wave chambers so that the valve assembly can direct air into both chambers simultaneously or direct air into one chamber while exhausting the other chamber or exhaust both chambers while blocking air from the source of forced air.
