Abstract:
1. A final control element for a control unit, in particular for a throttle body located in a gaseous medium-carrying conduit of an internal combustion engine, having a control shaft carrying the control unit in a manner fixed against relative rotation, having a power takeoff member, seated on the control shaft in a manner fixed against relative rotation, of a final control element gear that rotates the control shaft, and having an error sensor, detecting the rotary position of the control shaft, which error sensor has a rotor part, connected to the control shaft in a manner fixed against relative rotation, and a spatially fixed stator part, the improvement wherein the error sensor is a rotary angle sensor which measures without contact, and whose rotor part is embedded by material and positive engagement in the power takeoff member of the final control element gear.
