Abstract (en)
Adjusting device for adjusting a throttle valve of an internal combustion engine with progressive force/path transformation between an operating device and the throttle valve comprises a first restoring spring. Compensation of the increase in operating force is achieved. Preferred Features: A first (12) and a second spring (13) produce a restoring force. At least part of the increase in operating force induced by the first spring is equalized by the second spring. The sum of the restoring forces of the first and second springs is sufficient in the region of small throttle valve angles to cause complete closure of the throttle valve. The first spring is a torsion or flat spiral spring. The second spring is a tension or compression spring.
