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 (110) coupled to the spindle (100), and a valve unit (200). The lever arm (110) has a connecting element (112), designed as at least partially spherical, and the valve unit (200) has an accommodation region (212) with at least one first conical accommodation surface (214) in which the connecting element (112) is arranged.

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: The invention relates to an exhaust gas turbocharger comprising a turbine housing (200), a bearing housing (300), a rotor (400) which is rotatably mounted in the bearing housing and defines an axis of rotation (500) of the exhaust gas turbocharger, and a heat shield (100) which is arranged between the turbine housing and the bearing housing. The heat shield has a central hole (110) for positioning in the exhaust gas turbocharger; the center of the hole is positioned eccentric to the axis of rotation to prevent a rotation of the heat shield.
