Abstract
The invention relates to an apparatus for varying the position of a fuel control device that controls the output of an internal combustion engine and is connected to an operating element via a transmission device. In such an apparatus, a control motor can be operatively connected via a gear with a first rotary element connected to the control device and rotatably supported relative to a coaxial second rotary element connected to the operating element. The two rotary elements are prestressed by a spring that forces an arm each to contact one another at stops facing one another. To limit the control motor intervention to the regulated operating state, the invention provides a gear assembly that has at least one drive wheel operatively connected to the control motor, which drive wheel can be shifted from a position of repose, in which the operative connection with the first rotary element is interrupted, into a working position, in which the operative connection with the first rotary element is established to control the fuel control device.
