Abstract:
A pneumatic control system for a water cannon that has a barrel for holding a body of water, the barrel having an open end through which a body of water is driven by the application of a fluid-related force and a substantially closed end, the pneumatic control system comprising:first pneumatic control means for producing a pneumatic safety-on signal after a body of water has been expelled from the open end of the water cannon to place a pneumatic trigger in a disabled state and producing a pneumatic safety-off signal after a sufficient amount of water has been loaded into the barrel of the cannon to place a pneumatic trigger in an enabled state; and second pneumatic control means, responsive to a pneumatic fire signal from the pneumatic trigger, for producing a pneumatic firing signal for causing a valve to allow a fluid related force to be applied to the sufficient amount of water in the barrel of the water cannon.
