<p>The invention concerns a nozzle arrangement (2) for generating a water jet (3), comprising a nozzle plate (4) having a nozzle opening. In order for the nozzle arrangement (2) to be able to generate a water jet (3) that provides improved utilization as a light guide also in bodies of water with wave motion and that is constructively simple and producible in an inexpensive way, it has a nozzle sleeve (8) that surrounds the nozzle opening (6) at least partially and is arranged on the nozzle plate (4) and is provided with an inner sleeve wall surface (10) that surrounds a water jet (3) exiting from the nozzle opening at a safety spacing (S) that prevents unwanted contact with the water jet (3).</p> |
