Abstract
An apparatus for controlling the angular displacement of a throttle valve for an automotive vehicle includes a return spring attached to the rotational axis of the throttle valve which biases the rotational axis of the throttle valve towards its fully closed position, and which automatically moves the throttle valve to its fully closed position without excessive wear on the throttle valve or on a throttle chamber.
