A high pressure spray nozzle is provided having a central fluid stream that can be converted to a fan shaped fluid stream by rotation of a housing cap. Rotation of a second portion of the housing produces a cone shaped fluid stream which is coaxial with the central fluid stream.

High pressure coaxial flow nozzles

A multi-nozzle high pressure fluid sprayer which can be safely indexed to a selected nozzle while the sprayer is under high fluid pressure. The sprayer head contains an offset member having at least one fluid nozzle therein. The offset member can be rotated to align a selected nozzle with a source of high pressure fluid.

Central flow nozzle selector

A high pressure spray nozzle is provided having a central stream of fluid that can be changed to a coaxial flow of fluid by rotation of the housing cap to thereby produce an outer stream of fluid which is a coaxial to the central stream of fluid.

A multi nozzle high pressure fluid sprayer which can be safely indexed to a selected nozzle while the sprayer is under high fluid pressure. The sprayer contains separate seals at the inlet of each nozzle to permit a safe and effective indexing to either of the nozzles while the fluid is under high pressure or to provide a total shutoff of the fluid. The sealing arrangement includes a channel to provide back pressure to the seal area around each of the nozzles to prevent the seals from being disgorged or damaged as the sprayer head is indexed from nozzle to nozzle while under high pressure.
