FLAP ARRANGEMENT FOR A TURBINE OF AN EXHAUST-GAS TURBOCHARGER
Last updated:
Abstract:
The invention concerns a flap arrangement 10 for a turbine 2 of an exhaust-gas turbocharger 2, in particular for a wastegate valve of the turbine, having a spindle 100 for rotatable mounting of the flap arrangement 10 in a turbine housing 3, a lever arm 200, the lever arm 200 being coupled to the spindle 100, and a flap plate 300, the flap plate 300 being coupled to the lever arm 200. The flap plate 300 has a flexible part 330 in a radially outer region of the flap plate 300, such that by applying a closing force to the flap arrangement 10 when the flap plate 300 is in contact with a flap seat 500 in the turbine housing 3, elastic and/or plastic deformation of the flexible part 330 of the flap plate 300 can be caused to compensate for thermal deformation of the turbine housing 3, exhaust deposits and/or wear.
