ABSTRACT:
Fast acting airpowered water displays which may be computer controlled to operate over a wide range of duration and timings and methods of operating the same are disclosed. The water displays are comprised of one or more nozzles directed upward, typically just above or just below the water level in a fountain pool. Each nozzle is connected to a water reservoir submerged, at least in part, in a fountain pool and coupled adjacent the bottom of the reservoir to the inlet for the nozzle. The water reservoir, which may be in the form of a pipe of a substantial diameter, is also coupled to a check valve submerged in the fountain pool to allow water to refill the reservoir but to prevent water from escaping therefrom through the check valve. A solenoid valve controllably connects the upper portion of the water reservoir to a supply of air under pressure. The solenoid valve is operative between a first condition coupling the supply of air under pressure to the upper portion of the water reservoir, and a second condition venting the upper portion of the reservoir to the atmosphere. This arrangement allows operation of the water display in various ways ranging from short repetitive bursts of water up to an explusion of all the water in the reservoir in a single burst. Various features and alternate embodiments, including computer control, are disclosed.
