Abstract: The present invention relates to a spray device which comprises a nozzle for ejecting a jet of fluid. According to the invention, the spray device comprises a nozzle holder which is adapted to be gripped manually when using the spray device and which is movable relative to the nozzle essentially in parallel with the direction of the jet of fluid. The spray device further comprises a valve which is connected in front of the nozzle and is adapted to open when moving the nozzle holder in the direction of the jet of fluid relative to the nozzle. The nozzle is biased in the direction of the jet of fluid relative to the nozzle holder and the relative position of the nozzle holder to the nozzle is affected by the reaction power of the jet of fluid.
