A flow actuated pulsator for shooting water in consecutive pulses. The pulsator is powered by water flowing under pressure therethrough and includes a nozzle for ejecting water at high speed, a pulse valve which cycles through opened and closed states to effect on-off cycling of water flow and a sound effects generator for producing sound effects with each water pulse. The pulse valve is biased to an open state when the pulsator is not being actuated by flowing water so that an initial water flow initiates open-closed cycling. The pulse valve is biased to an open state following each closed cycle. The pulsator is built into a compressed air powered water gun designed to contain water and air under pressure and including an air pump for compressing air into the gun to pressurize water contained therein and a trigger coupled to a valve for manually shooting the gun by controlling flow of pressurized water to the pulsator.
A squirt gun for shooting a pulsating stream of water, said squirt gun comprising in combination a structure means for containing water and air under pressure, a pressurization pump means for compressing air into said structure means to pressurize water contained therein, a trigger means and a flow control valve means for facilitating manual control of shooting of said gun, a nozzle means for increasing the velocity of said water pulses as said water pulses are ejected from said gun when said gun is shooting, a flow actuated pulsator for controlling flow of pressurized water to said nozzle means when said gun is shooting and causing said water to flow in a pulsating manner and thereby causing said gun to shoot water pulses and a conduit means for fluidically coupling said nozzle means to said pulsator means, said control valve means being fluidically coupled to said pulsator means and controlling flow of pressurized water thereto, said pulsator means being mechanically actuated by water therethrough when said gun is shooting, said pulsator inturn controlling flow of water therethrough to said nozzle means.
A water pulsator for controlling the flow of water from a source and causing said water to flow as a sequence of pulses, said pulsator including in combination a pulse valve means for operating in a cyclic manner between opened and closed states to permit and inhibit water flow and a pulse flow responsive means for deriving operating power from water flowing through said pulsator and actuating said pulse valve means to effect open and closed states thereof, said pulsator further including a bias means for returning said pulse valve means to an open state to permit water flow whenever flow has been terminated, said pulse flow responsive means, said bias means and said pulse valve means being configured in combination such that water flowing through the pulsator actuates said pulse flow responsive means which in turn operates with said bias means to continuously open and close said pulse valve means causing said water flow to be periodic, said pulsator including in combination a nozzle means and a conduit means, said nozzle means functioning to increase the velocity of water pulses flowing from said pulsator and ejecting said water pulses at high velocity, said conduit means conducting water flow to said nozzle means, said pulsator further including a flow actuated sound generator means for producing audible sound effects, said sound generator including a sound flow responsive means for extracting operating power from flowing water, a mallet means and a diaphram means for producing sound, and a coupling means for operably coupling said sound flow responsive means to said mallet means to facilitate actuation of said mallet means by said sound flow responsive means, pressurized water flowing through said sound flow responsive means causing movement thereof and thereby actuation of said mallet means, said sound flow responsive means operating in a cyclic manner alternatingly causing said mallet means to move back and forth striking said diaphram in the process and producing audible sound.
