Abstract
A toy weapon for firing a charge of water includes a housing, water reservoir and a reciprocating piston mounted within a tube in the housing. The tube has a spring-biased, hinge mounted flap valve located at one end of the tube to effectively close the tube end. This valve also creates a sufficiently air-tight seal to allow the water charge to be suctioned from the reservoir into the tube. The tube holds the water charge, which is drawn into the tube on a back stroke of the piston, through a one-way valve in a conduit that connects the reservoir with the tube. The weapon is fired on a forward piston stroke, the water charge being pressurized in the tube and released as a single slug or burst of large droplets when the flap valve opens under increasing pressure of the water charge. A nozzle is provided downstream from the flap valve to help keep the water charge together and increase the velocity of the water as it is discharged from the weapon. A mechanical sound generator can be provided operated by movement of the piston shaft.
