ABSTRACT:
A load adjustment device is provided with a throttle valve (9) which determines the output of an internal combustion engine and is fastened, fixed for rotation, to a throttle-valve shaft (32), which is mounted in a throttle-valve housing (30). In idle operation, the throttle-valve shaft (32) is adjusted by an electric motor (14) and a four-link gearing (16) connected behind it. This includes a pinion (14) which is arranged on an output shaft of the electric motor (14) and meshes with a gear segment (50) which is connected for drive via a second link (53) to a rotor (54) which drives the throttle-valve shaft (32). Due to the advantageous arrangement of the four-link gearing (16), a very large transmission ratio can be achieved between the output shaft (40) of the electric motor 14 and the throttle-valve shaft (32), so that a very small, cost-efficient electric motor is sufficient.
