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.

A toy weapon for firing a charge of water comprising: (a) a housing defining a body of a toy weapon; (b) a tube supported by the housing, the tube defining a firing chamber to hold a charge of water; (c) a pivotally mounted flap valve located at one end of the tube through which end a water charge exits under pressure upon firing of the charge, so as to effectively close the one end of the tube sufficiently to retain a static charge of water in the tube; (d) a water reservoir external to the tube; (e) a conduit coupling the reservoir to the tube in proximity of the flap valve; (f) a one-way valve located between the reservoir and the tube and oriented to permit water to be drawn from the reservoir into the firing chamber; (g) a piston mounted to reciprocate within the tube, such that the piston draws the charge of water from the reservoir into the firing chamber on a back stroke and pressurizes the charge in the firing chamber on a forward stroke and (h) a piston spring positioned to bias the piston in a forward stroke direction.
