A nozzle which produces a wide liquid jet includes a housing open on one side with two longitudinal edges, one of which forms one edge of the nozzle aperture with the other edge of the nozzle aperture formed by the free end of a wall connected to the other longitudinal edge of the housing. Bolts are distributed over the width of the nozzle aperture outside the nozzle aperture for adjusting the wall over the nozzle width to slightly deform the wall and change the thickness of the nozzle aperture.
