ABSTRACT:
The present invention is a toy water gun which is operated by selectively releasing water from a water reservoir that is pressurized with air. The gun has amanually operated air pump which pressurizes a water reservoir and consequently pressurizes any water therein. The pressurized water has an avenue of release that is regulated by a trigger mechanism. When no force is applied to the trigger, the pressurized water is held at bay with no means of release. When force is applied to the trigger, water is released from the pressurized reservoir and is channeled through a narrow nozzle. The escape of the pressurized water through the narrow nozzle creates a stream of propelled water that lastas as long as the trigger is engaged or until the pressure on the water in the reservoir equals the ambient air pressure. Water is added to the present invention via at least one fill opening on the water reservoir. The reservoir itself is non-detachable from the gun housing. There is an orifice on the water reservoir separate from the fill opening which is connected to the housing and serves as both the entrance point of pressurized air from the air pump, and the exit point of the pressurized water.
