Abstract: A compressor is disclosed for a charging device of an internal combustion engine. An iris diaphragm mechanism is arranged upstream of the compressor wheel. An actuator is mechanically coupled to an adjusting ring of the iris diaphragm mechanism for transmitting torque of an actuator shaft to the adjusting ring for rotating the adjusting ring. A pivotable coupling pin is arranged eccentrically on the actuator shaft and has a bearing bush which is displaceable along a longitudinal axis of the coupling pin. The bearing bush is mounted between two fingers of an adjusting lever of the adjusting ring so as to be displaceable along the fingers. An outer contact surface of the bearing bush is spherical. Inner contact surfaces of the two fingers are cylindrical to correspond to the spherical outer contact surface of the bearing bush and are in sliding contact with the outer contact surface of the bearing bush.
