A turbocharger (1) with variable turbine geometry (VTG) having a guide grate (18) which surrounds a turbine wheel (4) radially at the outside, which has an adjusting ring (5) operatively connected to the guide blades (7) via associated blade levers (20) which are fastened to blade shafts (8) at one of the ends thereof. Each blade lever (20) has a lever head (23) which can be placed in engagement with an associated engagement recess (24), which has a base wall (26), of the adjusting ring (5), and which has a stop (25) at least for setting the minimum throughflow through the nozzle cross sections formed by the guide blades (7). The stop is a first support point (25) on the base wall (26), wherein, in the minimum throughflow position, the lever head (23) makes contact, via a wall surface (27) facing toward the base wall (26), with said first support point. |

1. A turbocharger (1) with variable turbine geometry (VTG)
a turbine housing (2) with a supply duct (9) for exhaust gases; having a turbine wheel (4) which is mounted rotatably in the turbine housing (2); and a guide grate (18)
which surrounds the turbine wheel (4) radially at the outside,which has a blade bearing ring (6),which has a multiplicity of guide blades (7) which have in each case one blade shaft (8) mounted in the blade bearing ring (6),which has an adjusting ring (5) operatively connected to the guide blades (7) via associated blade levers (20) which are fastened to the blade shafts (8) at one of the ends thereof, wherein each blade lever (20) has, at the other end, a lever head (23) which can be placed in engagement with an associated engagement recess (24), which has a base wall (26), of the adjusting ring (5), andwhich has a stop (25) at least for setting the minimum throughflow through the nozzle cross sections formed by the guide blades (7),wherein the stop is a first support point (25) on the base wall (26), wherein, in the minimum throughflow position, the lever head (23) makes contact, via a wall surface (27) facing toward the base wall (26), with said first support point.
