Abstract
A water discharge device, particularly a toy water gun, includes a portable housing containing a reservoir for a quantity of water; a discharge control device for controlling the discharge of water from the housing; and a hand-operated pump for manually pumping water from the reservoir through the discharge control. The discharge control device includes an expansible chamber having an inlet connected to the pump, an outlet through which the water is discharged, and a pressure-responsive valve controlling the outlet. The valve is normally closed to permit expansion of the reservoir and a build-up of water pressure during the pumping of water by the pump into the reservoir, but automatically opens when a predetermined pressure is reached in the chamber to discharge water through the outlet.
Claims20
A water discharge device, comprising:
- a portable housing containing a reservoir for a quantity of water;
- a discharge control for controlling the discharge of water from the housing;
- and a hand-operated pump for manually pumping water from the reservoir through the discharge control;
- said discharge control including an expansible chamber having an inlet connected to said pump, an outlet through which the water is discharged, and a pressure-responsive valve controlling said outlet;
- said valve being normally closed to permit expansion of said reservoir and a build-up of water pressure therein during the pumping of water by said pump into said reservoir, but automatically opening when a predetermined pressure is reached in said chamber to discharge water therefrom through said outlet.
