  • Patent number: 5323968
    Abstract: A water spray gun has a barrel, the front of which includes a nozzle which is operable to eject water in a chosen one of a number of different patterns. At the rear of the barrel there is provided a handle having a passage for water supplied to the gun. The admission of water through the handle and thence into the barrel is controlled by a trigger which is squeezable against the handle. In use, the pattern of water ejected by the nozzle is selected using a rotatable valve member within the rear end of the barrel. The annular position of the valve member is selected using a control element at the rear end of the barrel. The valve directs water either to a central passage or to an outer annular passage extending through the barrel to feed water to respective alternative areas of the nozzle.
