Definitions

  • the invention relates to a fluid flow machine of the radial type according to the Generic term of patent claim 1.
  • the invention is therefore based on the object of applying both requirements at the same time meet without the structural effort goes beyond the scope.
  • the torsion of the guide vanes results in the recesses during axial movement the slot ring both to a change in the exit angle after the Leitapparat, as well as a change in the free flow cross-section. This results in an optimal adaptation of the turbomachine unsteady states, for example at the entrance to an exhaust gas turbine of an ATL.
  • Fig. 1 shows a longitudinal section through a turbomachine, shown here Example of an exhaust gas turbine from an ATL.
  • the exhaust gas turbine consists essentially of a spiral housing 1 for supplying the exhaust gas, an adjustable diffuser 2, an impeller 3 and a housing 4.
  • the adjustable diffuser 2 consists of guide vanes 5 with a Twist. The twist is clearly shown in Fig. 3.
  • the guide vanes (5) are rotatable on the one hand with pins 6, but axially fixed in one Sliding ring 7 mounted, on the other hand in a slot ring 8, which is fixed to the housing 4th connected is.
  • the sliding ring 7 is concentric with a running axis 9 of the impeller 3 arranged and can, as indicated by the arrow, together with the guide vanes 5 be moved axially.
  • the guide device 2 makes one without excessive construction effort optimal adaptation to a transient amount of exhaust gas and exhaust gas enthalpy Internal combustion engine possible.
  • Fig. 3 shows the slot ring 8 in a view from the output side of the exhaust gas turbine
  • the torsion of the guide vanes 5 can be seen 1 slide ring 7 shown in Fig. 1 move in the axial direction, they twist because of their twist around their pins 6, since they can be seen in FIG. 2 Recesses 10 are performed with play.
  • the outflow angle and the free flow cross section vary at the same time. The construction effort is kept within reasonable limits.
  • the adjustable guide apparatus shown using the example of an exhaust gas turbine can of course be used also apply to compressors to extract the kinetic energy from there Impeller gas flow emerging to be converted into static pressure energy with as little loss as possible.
