Abstract: A waste gate valve actuator, that may be used for an exhaust gas turbocharger of a motor vehicle, may have a flap with a base surface to be supported on an edge of an inlet or outlet opening of a waste gate channel and a channel-side elevation, which at least in one cross section along its axial direction exhibits an outer contour with a first section and an adjoining section facing away from the base surface. The outer contour in the first section may have at least one outer tangent that includes a first angle deviating from zero with the axial direction, and in the second section may have at least two outer tangents spaced apart from each other in an axial direction that include the same second angle angle deviating from zero and the first angle with the axial direction, and/or wherein the elevation exhibits in particular a flat front surface facing away from the base surface, which in relation to the base surface-side floor surface of the elevation is offset toward a rotational axis of the flap.

Abstract: An exhaust gas recirculation device for a motor vehicle is disclosed with includes an unburnt gas line for guiding an unburnt gas flow and at least one exhaust gas feed line for supplying exhaust gas into the unburnt gas line. At least two discharge openings offset relative to each other in the circumferential direction of the unburnt gas line are provided in the unburnt gas line, by way of which the exhaust gas can be or is supplied to the unburnt gas line.

Abstract: An air intake device for an internal combustion engine of a vehicle is provided. The air intake device includes a cylinder head of a cylinder, an inlet port, which is connected to the cylinder head, and a guiding system. The guiding system includes a separating wall element that divides at least one portion of the inlet port with respect to the cylinder head into a first upper part port and second lower part port. The guiding system has a flap element for opening and closing the first upper part port.
