| Abstract: |
Method and apparatus for creating in a water pool a wave for surfing, the pool having a reservoir at one end open to the pool beneath the undisturbed water level of the pool, a fan connected to the reservoir for expelling air from it and drawing water from the pool into the reservoir to store water above the undisturbed water level of the pool, and a valve for selectively sealing the reservoir against the intrusion of air and rapidly ventilating the reservoir so that the stored water flows into the pool by gravity at a velocity near its theoretical limit.

We claim:
1. Apparatus for producing a surfing wave above the undisturbed level of water in a pool having a floor, said apparatus comprising:
- a reservoir having an interior volume disposed partially above and partially below the level of undisturbed water in a pool, generally opposed front and rear walls, and generally opposed side walls to form with said front and rear walls a first horizontal cross sectional area, each said wall terminating in a lower extremity to establish communication between said reservoir and said pool below said level of undisturbed water in said pool, said reservoir including a first aperture for admitting air, said first aperture having a second cross sectional area at least one third that of said first horizontal cross sectional area;
- suction means in communication with said reservoir for evacuating air from said reservoir; and
- valve means for selectively sealing said reservoir against the intrusion of air and rapidly opening said first aperture to ventilate said reservoir to the atmosphere.
