Definitions

  • the insert 30 is a flat annular piece, of the same dimensions as the wing-holding ring.
  • the fin ring is kept spaced from the insert by means of several spacers 34 of selected height so that the top of the fins makes a predetermined functional play with it.
  • FIG. 5 shows a turbocharger without insert.
  • the fin ring 22 is fixed to a wall 28 of the passage which communicates the volute chamber 14 with the turbine wheel 16.
  • the fins 24 make a nominal functional clearance e with the other face 46 or U-shaped face which delimits said passage.
