Abstract

A throttle-valve setting device has, for idle adjustment, a motor setting lever (10) which displaces a throttle valve (3) and is connected via a path-dependent controlling movement-reversal device (15) to a setting member (13) of a setting motor (12). Thereby, upon activation of the setting motor (12), the setting lever (10) first swings slightly in one direction and then in the other direction to the full-load position of the throttle valve (3).
