Abstract:
A toy gun is disclosed that may have a pressurized elastomeric supply bladder in fluid communication with an elastomeric pulse bladder via a trigger valve. The pulse bladder may also be in fluid communication with a pulse nozzle via a pulse valve that is operatively connected to the pulse bladder so that the pulse valve moves from a closed position to an open position when the pulse bladder expands. When the supply bladder is filled with pressurized liquid and the trigger valve is opened, pressurized liquid from the supply bladder is forced into the pulse bladder. As the pulse bladder expands, the expansion eventually causes the pulse valve to open and cause a burst of liquid to be discharged from the pulse bladder through the pulse nozzle. As the pulse bladder contracts during the burst of liquid, the pulse valve returns to the closed position so that the pulse bladder can continuously cycle through the sequence of filling with pressurized liquid and opening the pulse valve to release a burst of liquid as long as the trigger valve remains opened and the supply bladder forces pressurized liquid to the pulse bladder.
