Abstract
The invention relates to a turbocharger (1) in which, for damping the wastegate flap/wastegate lever system, an axially acting spring element is provided in order to reduce wear. The turbocharger (1) comprises a compressor (2) and a turbine (3) which has a turbine housing (4) and a wastegate device (6) with a regulating flap (7). The flap plate (7′) of the regulating flap (7) is arranged, via a lever (5), on a regulating flap shaft (9) which is guided in the turbine housing (4) by means of a bush (8). Here, the flap plate (7′) is preloaded against the lever (5) by means of a spring element (10).
