Abstract

Eine Lastverstellvorrichtung für eine die Leistung einer Brennkraftmaschine eines Kraftfahrzeuges bestimmende Drosselklappe (3) hat eine aus einem elastischen Material gefertigte Notlauffeder (17). Eine Rückstellfeder (12) ist als Stahlfeder gestaltet und spannt einen über die Notlauffeder (17) mit der Stellwelle (2) verbundenen Hebel (13) gegen einen gehäusefesten Anschlag (15) vor. Die Lastverstellvorrichtung ist hierdurch besonders einfach aufgebaut und läßt sich kostengünstig fertigen.

Figure 00000001
A load adjusting device for a throttle valve (3) which determines the performance of an internal combustion engine of a motor vehicle has an emergency running spring (17) made of an elastic material. A return spring (12) is designed as a steel spring and biases a lever (13) connected to the actuating shaft (2) via the emergency running spring (17) against a stop (15) fixed to the housing. As a result, the load adjustment device is particularly simple in construction and can be manufactured inexpensively.
