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.

A water spray gun comprising a barrel having a front end and a rear end; nozzle means at said front end and having two different water discharge areas; selectable direction means for selectively directing the water to at least a chosen one of said two different water discharge areas so as to select a pattern of water discharged by the nozzle means, said selectable direction means comprising two water flow passages in the barrel and a control element disposed at the rear end of the barrel and operative to select the water flow passage to which the water is directed; a handle having an internal passage for supplying water to the barrel; and a trigger member movable with respect to the handle to control the flow of water to the barrel through the handle. the front end of the barrel is formed with an outer tubular part and an inner tubular part, the water flow passages comprising an inner passage, leading to a jet-producing aperture means of the nozzle means, defined within the inner tubular part and an outer passage, leading to a spray-producing perforated plate of the nozzle means, defined between the two tubular parts; the selectable direction means comprises a rotatable valve member having a hollow stem and an oblique oval sealing flange mounted on the stem and the inner tubular part of the barrel has a read end which constitutes a sealed bearing for a front end portion of a stem of the valve member; proximate said bearing the rear end of the inner tubular part is externally stepped to form a rear terminal portion of increased diameter at which the inner tubular part is joined to the outer tubular part, and said portion of increased diameter is apertured to permit water flow into the outer passage between the two tubular parts; behind said rear terminal portion of the inner sleeve, the valve stem has a region of increased diameter at which the valve member is located against axial displacement in the barrel, and said increased diameter region of the valve member is also apertured to permit forward water flow, from the aforementioned chamber in the barrel behind it, into an intermediate space from which the water can enter the apertures in the increased diameter portion of the inner tubular part of the barrel.
