Abstract:
A spray device comprising a nozzle having a front portion for ejecting a jet of fluid from the front portion of the nozzle in a direction, a nozzle holder which may be gripped manually when using the spray device and being movable relative to the nozzle essentially in parallel with the direction of the jet of fluid, the nozzle holder further forming a portion of a valve assembly which opens by moving the nozzle holder in the direction of the jet of fluid relative to the nozzle, the nozzle being biased in the direction of the jet of fluid relative to the nozzle holder, while the nozzle and nozzle holder are urged together by the reactive power of the jet of fluid in opposition to said bias, wherein the reactive power of the jet of fluid counterbalances the bias extended against the nozzle in the direction of the jet of fluid such that, once opened, the valve assembly remains substantially open as the nozzle holder is grasped by an operator.
