Definitions

  • the second outlet angle measured against the diffuser axis is very particularly advantageously greater than the first outlet angle measured against the diffuser axis, whereby a particularly smooth transition of the fluid from the diffuser into the delivery tube is ensured, because the distance between the outlet sector of the diffuser and the inner wall of the diffuser section gradually becomes larger toward the delivery pipe.
  • the first outlet angle is advantageously at most 15 degrees, preferably in the range of 6 degrees and 12 degrees, and in particular at 10 degrees
  • the second outlet angle is preferably at most 30 degrees, advantageously in the range between 12 degrees and 24 degrees, and more specifically 18 degrees.
  • a difference angle between the first outlet angle and the second outlet angle in the range of 6 degrees to 12 degrees, preferably selected at 8 degrees.
  • FIG. 2b is for better understanding additionally an imaginary line L 'located, which illustrates the comparison of the course of the outlet sector 52', the gem.
  • Fig. 1a respectively.
  • Fig. 1b in the form of a single truncated cone with an angle of inclination ⁇ 1 ', as it is formed in a known from the prior art diffuser 5'.
