Abstract

A valve control unit, especially for internal combustion engines, having a valve fixed on a valve spindle which is mounted for angular rotation in a valve body supporting a control motor for positioning the valve spindle. The motor is coupled to the valve spindle through a gear mechanism and is disposed in the valve body with a sensor unit for sensing an adjusted angular position of the valve spindle. A cover is provided to be fastened on the valve body and the cover supports an electric clutch element, a bearing for an end of the motor shaft of the control motor and functional parts of the control motor such that assembly of the control motor is completed upon mounting the cover on the valve body.
