ABSTRACT:
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.
