Definitions

  • Such a turbocharger is known from EP 1 564 380 A1. To avoid weakening the adjusting ring this document proposes a stop which is integrally connected to the adjusting ring.
  • the projection of the stop of the known turbocharger limits the end positions by contact with mounting rings of the adjusting lever on the blades, which also makes precise adjustment of the end positions difficult, since the mounting rings of these blade adjustment levers are subject to manufacturing tolerances and on the other hand, as a result of the positioning (division) inaccuracies arise.
  • turbocharger specified in the preamble of claim 1, which allows a simplification of the assembly of the guide grid or diffuser, at least a simple and accurate adjustment of the minimum flow through the diffuser should be possible alone.

Grille fixieiL> ⁇ .i itsL, it is possible after the installation of the guide grille to rework this stop in a simple way for exact adjustment of the required stop position, since it is not integrally connected to the guide grille. If the need for a readjustment of one of the two end positions of the guide grid, it can be either simply selected and mounted a suitable fitment for the desired end position or adapted the intended stop member by reworking the projection and then mounted in the guide grille. Thus, it is possible to make a precise end position targeted, which is problematic in the generic turbocharger due to the integral formation of the stop.
  • the adjustment of the minimum flow is thus independent of turbine housing and other components of the turbocharger, such as e.g. the bearing housing. Also, the nozzle position between the bearing and turbine housing no longer has any influence on the minimum flow setting. Also, the wear of the adjusting lever and its engagement with the adjusting ring does not affect the minimum flow rate.
