<p>The nozzle has a block-shaped nozzle body (17) with a basic shape of cuboid and comprising broad longitudinal surfaces running on both sides of a central plane of the body. The central plane contains a central longitudinal axis of a nozzle channel, where a distance of the longitudinal surfaces is smaller than an inner diameter of an inlet (22) of an acceleration section (29) and is greater than an inner diameter of a cylindrical outlet section (31) of the channel. The longitudinal axis of the nozzle runs parallel to longitudinal edges (18-1, 18-2, 18-4) of the body.</p> |
