A water gun (10) is provided having a storage tank (18), a pressure tank (19), and a pump (32) for conveying liquid from the storage tank to the pressure tank. The conveyance of liquid from the storage tank creates a vacuum which is controller through a control valve (43) to refill the storage tank

A water gun (10) is provided having a storage tank (18), a pressure tank (19), and a pump (32) for conveying liquid from the storage tank to the pressure tank. The conveyance of liquid from the storage tank creates a vacuum which is controller through a control valve (43) to refill the storage tank with water in an efficient manner.

[ I claim:] [1.] A water gun comprising:first conduit means having one end open to ambience;a reservoir coupled to said first conduit means adapted to store a supply of liquid;a manual control valve coupled to said first conduit means between said reservoir and said open end, said control valve being manually operable between a closed position preventing the flow of fluid through said first conduit means with said reservoir maintained under a static vacuum pressure state and an open position allowing the flow of liquid through said first conduit means;second conduit means coupled to said reservoir for conveying the liquid from said reservoir; andpump means in fluid communication with said reservoir and said second conduit means for extracting liquid from said reservoir and depositing the liquid into said second conduit means;whereby with the control valve in its closed position the actuation of the pump means causes liquid to be drawn from the reservoir creating a static vacuum therein, thereafter the open end of the first conduit means may be submerged into a supplemental supply of liquid and the control valve actuated to its open position to allow the vacuum within the reservoir to draw at least a portion of the supplemental supply of liquid through the first conduit means and into the reservoir.
