Claim Text:
1. A nozzle comprising: a nozzle surface area and a nozzle rim, first and second guiding devices alternatingly provided on the nozzle rim in a circumferential direction, a plurality of wall elements, wherein the first guiding devices have a converging shape in a flow direction, wherein the second guiding devices have a diffusing shape in the flow direction, wherein the first guiding devices each have a first guide wall circumferentially extending between two first adjacent ones of the wall elements, with the first guide wall forming a first trailing edge and two first edges to the two first adjacent ones of the wall elements, wherein the second guiding devices each have a second guide wall circumferentially extending between two second adjacent ones of the wall elements, with the second guide wall forming a second trailing edge and two second edges to the two second adjacent ones of the wall elements, and wherein each wall element connects a first guiding device and a second guiding device while forming part of both guiding devices, with each wall element having a first edge to one of the first guide walls, a second edge diverging from the first edge in an axial direction toward one of the second guide walls and a trailing edge, wherein at least some of the first guide walls of the first guiding devices and at least some of the second guide walls of the second guiding devices have different axial lengths, so that the first and second trailing edges have different axial positions; wherein the wall elements have a curved course in the axial direction.
