ABSTRACT:
An actuator unit including a step-up which varies over an adjustment path, between a control motor and a wheel connected to the throttle body in a manner fixed against relative rotation offers the advantage that in certain positions of the throttle body, the required increased torque can also be brought to bear by a relatively low-torque control motor. The actuator unit is intended in particular for internal combustion engines for motor vehicles.
