ABSTRACT:
A load adjustment device is provided with a throttle valve (9) which determines the output power of an internal combustion engine and is connected, fixed for rotation, to a throttle-valve shaft (32) which is mounted in the throttle valve housing (30). The throttle-valve shaft (32) has an accelerator-pedal-side, mechanical articulation side and a setting-motor-articulation-side, with which there is associated a coupling element for the mechanical uncoupling of the throttle valve from an electric motor (14), as well as means for reporting the instantaneous position of a throttle-valve lever (21) arranged on the throttle-valve shaft (32) and of a driver element (25) to an electronic control device (17). The report device has a first transmission member which is arranged fixed for rotation on the throttle-valve shaft (32) and cooperates with a first potentiometer (23) as well as a second transmission member which is mounted for free rotation on the throttle-valve shaft (32) and cooperates with a second potentiometer (24). All parts of the device for the reporting are arranged in a dust-protected housing ( 36) so that a very compact arrangement is obtained.
