Abstract
A pneumatic wave-generator for a wave pool, comprising a caisson divided into a plurality of wave-generating chambers, a ventilator space provided with a powered source of forced air, and a system of conduits coupled to an air-directional valve which is capable of effecting forced aspiration and expiration above the water surfaces in the wave-generating chambers. The air-directional valve efficiently and selectively directs air into and out of a chamber, as desired, provides a seal against the unwanted flow of air, has a reduced number of moving pieces, is mechanically efficient, and has limited wear points.
