A water gun which utilizes a piston movable within a piston cylinder by a manually operated handle. Movement of the piston to a retracted position within the piston cylinder will result in supplying water from a water reservoir into the piston cylinder. Moving of the piston in an inward position within the piston cylinder will result in expelling water from the piston cylinder into an elastic bladder. The quantity of water being expelled from the piston cylinder within the elastic bladder will cause the elastic bladder to expand substantially, and at the point of full inward motion of the piston, the handle will come into contact with a discharge valve which will be moved to cause release of the water that is confined within the elastic bladder. This water is to be expelled through a nozzle to be emitted into the ambient in a form of a stream.

[ What is claimed is:] [1.] A water gun comprising:a housing;a reservoir mounted on said housing, said reservoir to contain a supply of water;a piston cylinder formed in said housing, an inlet passage connecting with said piston cylinder, a one-way valve normally closing said inlet passage relative to said piston cylinder, an outlet passage connecting with said piston cylinder;a piston movably mounted within said piston cylinder;a handle connected to said piston, said handle being movable between a retracted position and an extended position, said piston being manually moved within said piston cylinder by said handle during movement of said handle between said retracted position and said extended position, said piston being movable in an inward direction and an outward direction, movement of said piston in said outward direction opens said one-way valve and permits water to flow into said inlet passage and into said piston cylinder, movement of said piston in said inward direction causes water to flow from said piston cylinder into said outlet passage with said one-way valve being closed; andan elastic bladder connected with said outlet passage, said elastic bladder having a discharge passage, said discharge passage being normally closed by a discharge valve assembly, said elastic bladder to receive water from said outlet passage which will cause said elastic bladder to expand due to a quantity of water contained within said elastic bladder where said quantity of water exceeds the volume of said elastic bladder in its unexpanded state, said handle to contact said discharge valve assembly causing said discharge valve assembly to move to an open position resulting in discharging of said quantity of water into the ambient.
