  • a pressureless fluid store for gaseous or liquid fluids can also be used, with an optional additional compressor and in particular a fluid pump then being provided.

  • At least one inlet and / or at least one chamber 2; 302 and in particular the primary fluid inlet 100 and / or the secondary fluid inlet 200 have at least one fluid line means 102 and in particular at least one primary fluid line means 102 or secondary fluid line means, via which they are in fluid connection with a fluid reservoir 104 or a fluid pump.

  • a guide in or on the closure means is also conceivable.
  • the fluid reservoir 104 is optionally fed via the fluid line 102 to the nozzle 10 or in the inlet area 8 to the main mixing chamber 2, where the fluid and in particular the primary fluid runs in a spiral around the main mixing chamber 4 and is guided to the closure part 12.

  • An active delivery of the quaternary fluid and / or the primary fluid via the respective inlet 400 is, of course, also optional; 200 can be implemented, for example using appropriate pressure reservoirs or feed pumps.
  • Fig. 5 shows an embodiment in which the tertiary fluid inlet 300 is optionally designed to be pivotable about a pivot axis A S300 running orthogonally to the main flow direction R X2 in the confluent chamber 4, here the main mixing chamber 4, in a pivot direction counter to the main flow direction R X2 in a range of 90 to 150 degrees is.

  • the tertiary fluid is introduced tangentially further in the direction of the main flow direction R X2 of the main mixing chamber 2 and to that extent the fluid flow is accelerated, in particular in the outlet region of the chamber.
  • the pivot angle ⁇ is represented here by the pivot angle ⁇ 1 of 90 degrees and the further pivot angle of ⁇ 2 with 150 degrees, always starting from the main axis of extension Ax.
  • the Venturi vortex tube effect and the flow velocity in the axial direction, in particular in the direction R X500 of the fluid mixing device, can be influenced via the size of the pivoting angle.
