Lastverstellvorrichtungen der vorstehenden Art sind allgemein unter der Bezeichnung E-Gas zur Leistungsverstellung der Brennkraftmaschine von Kraftfahrzeugen bekannt. Durch den Einsatz einer einzigen Drehfeder als Notlauffeder und als Rückstellfeder ist die Lastverstellvorrichtung besonders kompakt aufgebaut und weist ein besonders geringes Gewicht auf.Load adjustment devices of the above type are generally under the Designation E-gas for power adjustment of the internal combustion engine from Motor vehicles known. By using a single torsion spring as The load adjustment device is special as an emergency spring and as a return spring compact design and particularly light in weight.
Aus der DE 195 24 941 A1 ist eine Lastverstellvorrichtung für ein die Leistung einer Brennkraftmaschine bestimmtes Stellglied bekannt, daß auf einer Stellwelle einen drehbar gelagerten Anschlaghebel aufweist. Dabei ist eine Drehfeder zwischen diesem Anschlaghebel und der Stellwelle gespannt. Hierzu umschließt ein annähernd U-förmig gebogenes Ende der Drehfeder einen Zapfen des Anschlaghebels teilweise. Ebenfalls eine Befestigung einer Drehfeder mittels eines annähemd U-förmig gebogenen Endes an einem festen Element beschreibt die DE 27 28 022 A1.From DE 195 24 941 A1 is a load adjustment device for the Performance of an internal combustion engine certain actuator known to an actuating shaft has a rotatably mounted stop lever.

Weiterhin können Vibrationen des Kraftfahrzeuges zu einem Lösen der Befestigungen der Drehfeder führen. Zur Befestigung der Drehfeder an der Stellwelle hat die Stellwelle in der Regel einen Schlitz, in den die Drehfeder eingesteckt wird. A disadvantage of the known load adjustment device is that the ends of the Torsion spring can be attached to the adjusting shaft and the support part must, since the torsion spring acting in both directions of rotation of the control shaft Actuates. Furthermore, vibrations of the motor vehicle can increase loosen the fastenings of the torsion spring.
