Abstract:
1. A device for generating a jet stream of air entrained water, comprising: a water inlet adapted to receive a water flow from a reservoir; an air inlet adapted to admit entrance of air stream; a water and air mixing body defining: first and second pumps respectively having first and second internal ports which are communicated respectively with said first water and air transit chambers, and which are disposed respectively downstream of said first water and air inlet ports and upstream of said first water and air outlet ports, said first and second pumps being configured to sequentially pump in and out of said first and second internal ports respectively, the water flow and the air stream respectively, thereby accelerating the speeds of the water flow and the air stream respectively so as to generate raised water and air pressures, respectively; first and second valves disposed respectively between said first water inlet port and said first internal port, and between said first air inlet port and said second internal port, each of said first and second valves being further disposed to be movable between third and fourth valves disposed respectively between said second water inlet port and said second water outlet port, and between said second air inlet port and said second air outlet port, each of said third and fourth valves being further disposed to be moved by the respective one of the raised water and air pressures from a second closed position, where
