Abstract
A throttle flap adjustment unit having a throttle flap fastened to a throttle flap shaft. The throttle flap shaft is rotatably journaled in a throttle flap end pipe. A servomotor is provided for adjusting the throttle flap shaft and is connected to the throttle flap shaft by a drive. A sensor unit is provided for determining a position of the throttle flap shaft. A cover is provided to be fastened onto the throttle flap end pipe, wherein the servomotor is positioned in the cover and controllable over an electrical coupling element, wherein the servomotor (6) has a front portion (12) oriented toward the throttle flap end pipe and formed as an end plate (13) for the drive shaft of the servomotor. The end plate (13) also serves to center the servomotor (6) with respect to the throttle flap end pipe (4) and also to center the servomotor (6) in the cover (7).
