Claim 15:
16. The water gun of claim 15, wherein when the extended shaft of the shuttle valve is received within the nozzle and the discharge port of the integral housing, such that as shuttle valve approaches the shuttle valve engaged position, a first clearance between the diameter of the extended shaft and a diameter of an orifice of the nozzle in fluid communication with the discharge port provides a first impendence to flow of water discharged through the nozzle, and the transition segment and a diameter of the shaft segment of the shuttle valve provides a second impendence which decelerates movement of the shuttle valve resulting from a volume of water dissipated between the first impendence and the second impedance due to a difference in diameter of the shaft segment and the extended shaft diameter during movement of the shuttle valve to the shuttle valve engaged position prior to a termination of flow of water, such that dynamic stress on the elastomeric seal is decreased.
