    摘要： A water gun, having a trigger control, provides repeated discharge of metered volume stream of water, uses a sealed chamber containing a refillable reservoir of water pressurized by compressed air. The pressurized water supply is connected to a tubular housing, which transports the stream of water to a second end of the tubular housing to a nozzle assembly. A trigger controlled valve which is connected to a trigger mechanism, having an operator controlled trigger, initiating the flow of the stream. The initiated stream is volumetrically metered and terminated by a shuttle valve, which terminates flow upon reaching a valve seat which decelerates the velocity of the shuttle before it contacts the valve seat, which reduces stress on the seal. A method of sequential resetting is provided to reset the trigger valve, trigger mechanism and shuttle valve, enabling a repeated metered discharge.

    摘要： A toy water pistol having a detachably securable watercontaining cartridge which serves not only as a reservoir for a substantial amount of water, but also as a biasing means for the trigger. The cartridge is constituted as a multiply-pleated bellows which is retained in a simulated barrel portion of the pistol. This portion is open on one side, permitting the cartridge to be easily inserted and removed. The forward end of the bellows has an orifice through which water is ejected when the bellows is compressed by squeezing of the trigger. A plunger having longitudinally spaced transverse webs is guided by axially extending, circumferentially spaced ribs within the barrel.
