Abstract: The invention relates to a valve assembly (10) for a charging device, in particular for a wastegate of an exhaust gas turbocharger, comprising a spindle (100), a lever arm (300) coupled to the spindle (100), and a valve disk (200). The valve disk (200) is coupled to the spindle (100) via the lever arm (300) in such a way that the valve disk (200) can be tilted about a first axis (610) and about a second axis (620).

Abstract: A wastegate assembly for controlling flow of exhaust gas includes a valve element having a valve body and a valve shaft. The wastegate assembly further includes a spindle having a head defining an opening and including a flat surface. The wastegate assembly further includes a washer coupled to the valve shaft and spaced from the spindle for securing the spindle to the valve shaft. The washer defines a bottom washer surface facing the flat surface of the spindle head, with the bottom washer surface including a flat region and a beveled region. A biasing member is disposed between the flat surface of the spindle and the flat and beveled regions of the washer. The beveled region extends oblique relative to the flat region for minimizing contact between the washer and the biasing member beyond the flat region.
