Definitions

  • the present invention relates to a deflection bend for deflecting a waste water flow
  • Deflection bends have become known from the prior art.
  • deflection bends are typically a limiting factor with regard to the discharge capacity, because a stratified flow in a pipe running essentially in the horizontal direction has to be converted into a vertical ring flow in a pipe running in the vertical plane.
