Abstract
A hydrodynamic converter has a working chamber through which an operating medium can flow. A pump wheel is connected to a drive shaft and a turbine wheel is connected to a driven shaft. At least one positioning blade can be adjusted by an adjustment device. In order to provide a compactly formed and robust hydrodynamic converter of this type, having a hard-wearing adjustment device for adjusting at least one positioning vane, the adjustment device includes an actuating drive with ring elements. Each ring element is disposed coaxially in relation to the drive shaft. A first ring element is connected to the at least one positioning blade for transmitting a positioning force or a positioning torque via a diverting device. The first ring element can be rotated relative to a second ring element in the circumferential direction of the drive shaft.
