| Abstract: |
A pneumatic/hydraulic wave generator is associated with the deep end of a swimming pool and includes a pneumatic system with a pair of inner caissons and a pair of outer caissons. The caissons communicate with the swimming pool through a submerged passage. A pneumatic system includes a motor-driven fan which communicates selectively with duct lines to the caissons through a pair of two-position air directional valve assemblies. When the caissons are actuated with pressurized air from the fan, the water levels therein are driven down, creating waves in the swimming pool.

What is claimed and desired to be secured by Letters Patent is as follows:
1. A pneumatic/hydraulic wave generator, which comprises:
- (a) a hydraulic system including first and second caissons each having:
- (3) an open passage at said lower end; and
- (b) a pneumatic system including:
- (2) a manifold communicating with said blower means;
- (3) a first duct line communicating with said first caisson;
- (4) a second duct line communicating with said second caisson;
- (5) an air directional valve assembly having a first position communicating said manifold with said first duct line and a second position communicating said manifold with said second duct line;
- (6) said air directional valve assembly including actuating means adapted for moving said air directional valve assembly between its first and second positions; and
- (7) a relief valve assembly selectively communicating one of said caissons with the atmosphere.
