Claim Text:
1. A nozzle, comprising: a nozzle wall having an inner face and an outer face, and one or both of the following: a turbulence-generating and/or vortex-generating structure disposed on said inner face of said nozzle wall and projecting radially inwardly from said nozzle wall, said turbulence-generating and/or vortex-generating structure, which is disposed on said inner face of said nozzle wall, having in a radially inward direction, a height being constant along an inner periphery of said nozzle wall, said turbulence-generating and/or vortex-generating structure, which is disposed on said inner face of said nozzle wall, extending along an entire amount of said inner periphery of said nozzle; and/or a turbulence-generating and/or vortex/generating structure disposed on said outer face of said nozzle wall and projecting radially outwardly from said outer face, said turbulence-generating and/or vortex-generating structure, which is disposed on an outer face of said nozzle wall, having a height being constant along an outer periphery of said nozzle wall, said turbulence-generating and/or vortex-generating structure, which is disposed on an outer face of said nozzle wall, extending along an entire amount of said outer periphery of said nozzle wall; wherein at least one structure selected from the group consisting of said turbulence-generating and/or vortex-generating structure disposed on said inner face of said nozzle wall and said turbulence-generating and/or vortex/generating structure disposed on said outer face of said nozzle wall is a zigzag-shaped structure.
