Nozzle with baffles

The nozzle has first and second guide devices (10, 20) arranged on a nozzle housing surface (4) and a nozzle rim (9) in a circumferential direction. The first guide device is provided with a first azimuthal guidance wall (11) and two wall elements (30). The second guide device is provided with a second azimuthal guidance wall (21). The wall elements are provided with two trailing edges (13, 23), where one of the edges is diverged to the other edge in an axial direction. The guidance walls have different axial lengths such that diverting edges (12, 22) have different axial positions.
