A valve device for a turbine of an exhaust gas turbocharger includes a valve element for at least partial fluidic shutting of a bypass line via which a turbine wheel of the turbine can be bypassed by exhaust gas. The valve device also has an actuating arm which is coupled in an articulated manner to the valve element and via which the valve element can be pivoted and has at least one spring element via which the valve element is supported on the actuating arm. The valve element has at least one uneven supporting surface via which the spring element is supported on the valve element.

A method operates a particulate filter through which exhaust gas can flow in a vehicle, in which ash is introduced into a filter body of the particulate filter, wherein at least one ash former or at least one ash component is arranged on at least one carrier material upstream of the filter body in the direction of flow of the exhaust gas.

A device for actuating a flap, in particular a wastegate flap in an exhaust gas turbocharger for an internal combustion engine, includes a control rod, which can be moved by an actuator substantially in an axial direction and is guided in a fist gate via a first pin at the side thereof facing away from the actuator. A carriage is articulated on the first pin and is guided in the first gate via a second pin on the side facing away from the first pin, wherein a pivot lever is articulated on the second pin and, on the side facing away from the second pin, the pivot lever is rotatably mounted in a machine housing, preferably a turbine housing, and the flap is arranged on the pivot lever on the side facing away from the second pin. By way of the articulated design, a non-linear adjustment of the flap is possible.
